1 00:00:06,540 --> 00:00:08,280 - [Dave] Hey, Dave here with another video. 2 00:00:08,280 --> 00:00:12,210 We're gonna talk about CPU and RAM analysis 3 00:00:12,210 --> 00:00:15,330 on my virtualization host here. 4 00:00:15,330 --> 00:00:19,960 So I'm running VMware Workstation on my AV editor computer 5 00:00:21,510 --> 00:00:23,010 I have a lot of virtual machines here; 6 00:00:23,010 --> 00:00:24,303 we've shown these before. 7 00:00:25,890 --> 00:00:28,260 The most monstrous of these 8 00:00:28,260 --> 00:00:31,560 is this Windows 10 virtual machine. 9 00:00:31,560 --> 00:00:32,393 So it's kind of funny. 10 00:00:32,393 --> 00:00:34,890 I'm running Windows 10 Pro on this system, 11 00:00:34,890 --> 00:00:38,760 but this virtual machine is also a Windows 10 Pro. 12 00:00:38,760 --> 00:00:40,710 Now, if you look, you can see 13 00:00:40,710 --> 00:00:44,310 that I set it up as 8 gigabytes of memory 14 00:00:44,310 --> 00:00:45,870 and six processors. 15 00:00:45,870 --> 00:00:48,960 Really, it's one processor with six cores. 16 00:00:48,960 --> 00:00:52,890 So I wanted to see how massive a virtual machine 17 00:00:52,890 --> 00:00:53,823 I could make. 18 00:00:54,660 --> 00:00:56,523 And these aren't the defaults. 19 00:00:57,510 --> 00:01:02,400 You can go less than this, and normally you would, 20 00:01:02,400 --> 00:01:04,200 but I wanted to see how powerful this is. 21 00:01:04,200 --> 00:01:06,390 This is a pretty powerful guy. 22 00:01:06,390 --> 00:01:09,150 Now, if we go to the Virtual Machine Settings here, 23 00:01:09,150 --> 00:01:11,010 you'll see processors, six. 24 00:01:11,010 --> 00:01:15,840 Really, it's one processor, number of core is six, 25 00:01:15,840 --> 00:01:17,550 so total processor core is six. 26 00:01:17,550 --> 00:01:19,470 But when you're dealing with virtualization, 27 00:01:19,470 --> 00:01:22,500 they just look at that as x amount of CPUs 28 00:01:22,500 --> 00:01:25,560 or x amount of processors, in this case, six. 29 00:01:25,560 --> 00:01:28,593 8 gigs of memory, 60 gigs for the hard drive. 30 00:01:29,670 --> 00:01:34,670 Current size is 14 gig that I can use out of that 60 gigs. 31 00:01:34,950 --> 00:01:36,090 So, really, I could have gotten away 32 00:01:36,090 --> 00:01:38,223 with 20 or maybe 30 gig, 33 00:01:39,300 --> 00:01:41,940 not really necessary to have it 60 gig. 34 00:01:41,940 --> 00:01:46,200 But not all that space is used on the local system, 35 00:01:46,200 --> 00:01:48,540 so you gotta keep that in mind. 36 00:01:48,540 --> 00:01:51,270 Anyways, I wanna boot this up to take a look 37 00:01:51,270 --> 00:01:56,270 at the resources that are being used on this computer. 38 00:01:56,760 --> 00:02:01,200 So right now, if we look, I have a lot of apps running, 39 00:02:01,200 --> 00:02:04,620 but if we look here, we see the CPU's at about 4% usage. 40 00:02:04,620 --> 00:02:08,343 This is my actual system, the AV editor computer. 41 00:02:09,240 --> 00:02:11,880 So we're at CPU 4% usage, 42 00:02:11,880 --> 00:02:16,880 and we're using 4.6 gigabytes of the memory. 43 00:02:18,030 --> 00:02:20,400 If we boot up the virtual machine, though, 44 00:02:20,400 --> 00:02:22,020 this is gonna skyrocket. 45 00:02:22,020 --> 00:02:26,910 So let's leave this open here, put this in the corner, 46 00:02:26,910 --> 00:02:30,483 and we'll power on this Windows 10 virtual machine. 47 00:02:31,590 --> 00:02:36,183 And when we do that, you'll see these resources go up. 48 00:02:38,220 --> 00:02:41,430 Okay, you can see it was booting in the background. 49 00:02:41,430 --> 00:02:45,330 Yeah, CPU 42%. 50 00:02:45,330 --> 00:02:47,610 Memory's going up, up, up, up, up. 51 00:02:47,610 --> 00:02:51,930 Well, it's gotta use that 8 gigs of RAM, right? 52 00:02:51,930 --> 00:02:54,840 So that's gonna go higher and higher as this gets booted up. 53 00:02:54,840 --> 00:02:57,210 And it's a little bit slow, by the way, 54 00:02:57,210 --> 00:02:59,673 'cause it's such a monstrous virtual machine. 55 00:03:00,750 --> 00:03:04,050 All right, still at 43%, 9.2 gig. 56 00:03:04,050 --> 00:03:05,853 Here we go. We're in. 57 00:03:07,230 --> 00:03:08,970 All right, that number's just gonna go up 58 00:03:08,970 --> 00:03:10,680 farther and farther. 59 00:03:10,680 --> 00:03:12,970 So I'm gonna actually log in 60 00:03:14,370 --> 00:03:17,223 to that Windows 10 virtual machine. 61 00:03:19,200 --> 00:03:22,020 And you use more memory when you're logged in 62 00:03:22,020 --> 00:03:25,740 and you have an actual user profile loaded up, okay? 63 00:03:25,740 --> 00:03:29,370 So that is the virtual machine. 64 00:03:29,370 --> 00:03:30,597 Just can't see it all. 65 00:03:30,597 --> 00:03:33,870 All right, now let's look at the... 66 00:03:33,870 --> 00:03:36,630 Here we go. CPU is still at 30%. 67 00:03:36,630 --> 00:03:38,100 It's gonna hover pretty high 68 00:03:38,100 --> 00:03:39,930 as this virtual machine is running. 69 00:03:39,930 --> 00:03:43,230 And the memory is now at 12.9 gig. 70 00:03:43,230 --> 00:03:44,220 What was it before? 71 00:03:44,220 --> 00:03:46,680 It was at the 4 or 5 gig 72 00:03:46,680 --> 00:03:50,250 and we have to use that 8 gigs of memory 73 00:03:50,250 --> 00:03:53,850 'cause I assigned that to this virtual machine. 74 00:03:53,850 --> 00:03:58,833 So you could see the resources that are used are massive, 75 00:03:59,790 --> 00:04:02,130 massive amount of resources, 76 00:04:02,130 --> 00:04:04,260 and that can really bog down a system. 77 00:04:04,260 --> 00:04:06,690 So in some cases you may need 78 00:04:06,690 --> 00:04:08,850 to kind of tone it down a little bit 79 00:04:08,850 --> 00:04:12,510 and you might not need that much. 80 00:04:12,510 --> 00:04:14,463 So I'm gonna shut down. 81 00:04:16,050 --> 00:04:17,940 I'm gonna shut down that guest. 82 00:04:17,940 --> 00:04:21,630 And when we do so, immediately, the CPU goes down to 4%, 83 00:04:21,630 --> 00:04:25,110 the memory goes down to 4.6 where we were at before. 84 00:04:25,110 --> 00:04:28,170 So we can edit these virtual machine settings, 85 00:04:28,170 --> 00:04:29,070 and we'll change it. 86 00:04:29,070 --> 00:04:32,400 We'll change the memory down to say 2 gig, 87 00:04:32,400 --> 00:04:36,573 and the processors, we'll just set that to one core. 88 00:04:38,730 --> 00:04:40,050 Click OK. 89 00:04:40,050 --> 00:04:43,203 That changes that guy, and I'll power it back on. 90 00:04:44,130 --> 00:04:47,403 Let that boot, and we'll check the difference here. 91 00:04:49,410 --> 00:04:54,150 Now my system's at about 15% CPU usage, 92 00:04:54,150 --> 00:04:55,900 and the memory only went up to 6.4. 93 00:04:57,120 --> 00:05:00,600 So the throttling of resources is important. 94 00:05:00,600 --> 00:05:04,200 And, really, it logged in at about the same speed. 95 00:05:04,200 --> 00:05:05,550 It's a little slow. 96 00:05:05,550 --> 00:05:07,110 Bringing up the apps is a little slow 97 00:05:07,110 --> 00:05:09,120 'cause Windows 10 is a monster by itself, 98 00:05:09,120 --> 00:05:11,160 but this is a big virtual machine 99 00:05:11,160 --> 00:05:13,500 to be running Windows 10 inside a Windows 10, 100 00:05:13,500 --> 00:05:15,750 even with a powerful CPU 101 00:05:15,750 --> 00:05:18,180 like the one I have on this computer. 102 00:05:18,180 --> 00:05:19,890 But it runs. It's going. 103 00:05:19,890 --> 00:05:24,540 And it's really not going much slower than it was before 104 00:05:24,540 --> 00:05:27,150 with the higher amount of resources. 105 00:05:27,150 --> 00:05:29,970 And this frees up a lot for my main system. 106 00:05:29,970 --> 00:05:33,960 So you have to be ready to turn down the resources 107 00:05:33,960 --> 00:05:35,820 or bring them up if necessary, 108 00:05:35,820 --> 00:05:38,400 let's say if you're running a server. 109 00:05:38,400 --> 00:05:40,743 So you have to be ready to modify those. 110 00:05:41,640 --> 00:05:43,593 But it still uses a lot of power, 111 00:05:44,880 --> 00:05:48,390 13, 14, 15% CPU power, 112 00:05:48,390 --> 00:05:49,980 another couple gigs of memory, 113 00:05:49,980 --> 00:05:51,180 and it adds up over time. 114 00:05:51,180 --> 00:05:52,080 And that's one of the reasons 115 00:05:52,080 --> 00:05:55,170 I increase the memory on my system. 116 00:05:55,170 --> 00:05:56,340 But the better way to do this 117 00:05:56,340 --> 00:05:59,193 is to run these virtual machines off of a server. 118 00:06:00,360 --> 00:06:05,100 So if we look here, we have the ESXi server that I built. 119 00:06:05,100 --> 00:06:06,720 And if we look in Virtual Machines, 120 00:06:06,720 --> 00:06:11,720 what I did was I uploaded that same Windows 10 OS, 121 00:06:13,380 --> 00:06:15,600 that same virtual machine. 122 00:06:15,600 --> 00:06:17,733 Okay, and this is currently running, 123 00:06:18,720 --> 00:06:22,320 and it's currently using 4 gigahertz of our CPU 124 00:06:22,320 --> 00:06:24,990 and 8 gigabytes of memory. 125 00:06:24,990 --> 00:06:27,240 But this will throttle up and down. 126 00:06:27,240 --> 00:06:28,893 It'll go down quite often. 127 00:06:31,620 --> 00:06:36,093 So if we look here, we see currently used, 4 gigahertz, 128 00:06:37,350 --> 00:06:40,740 free, 10.8 gigahertz on the server. 129 00:06:40,740 --> 00:06:45,740 So this looks at the CPU that we have as four cores, 130 00:06:45,840 --> 00:06:49,740 so it multiplies the maximum frequency, which is 3.7, 131 00:06:49,740 --> 00:06:53,313 it multiplies that by four to get the total. 132 00:06:54,570 --> 00:06:57,480 And that capacity is 14.8, 133 00:06:57,480 --> 00:07:00,300 we're using 4 gigahertz of that right now. 134 00:07:00,300 --> 00:07:02,550 But actually this number throttles down a lot, 135 00:07:02,550 --> 00:07:05,043 depending on what the virtual machine is doing. 136 00:07:06,570 --> 00:07:08,910 And so the beauty of doing it from the server 137 00:07:08,910 --> 00:07:10,380 and having the virtual machines 138 00:07:10,380 --> 00:07:12,690 on an actual type 1 hypervisor 139 00:07:12,690 --> 00:07:15,540 is that we can connect to them from anywhere, 140 00:07:15,540 --> 00:07:18,930 and it's the server's CPU and memory that's used, 141 00:07:18,930 --> 00:07:20,463 especially the memory. 142 00:07:21,810 --> 00:07:23,250 And then we can access them 143 00:07:23,250 --> 00:07:27,180 from something like a VMware Workstation client. 144 00:07:27,180 --> 00:07:29,403 And, in fact, I have it running here. 145 00:07:30,667 --> 00:07:34,290 Here's the server, 10.252.0.108, 146 00:07:34,290 --> 00:07:36,120 and here's that client inside there 147 00:07:36,120 --> 00:07:37,230 that we were just looking at, 148 00:07:37,230 --> 00:07:38,830 I'm just looking at it remotely. 149 00:07:40,350 --> 00:07:42,840 And so we can log in here. 150 00:07:42,840 --> 00:07:45,060 There we go. We're in. 151 00:07:45,060 --> 00:07:47,433 I'm actually gonna shut down the local one. 152 00:07:48,270 --> 00:07:50,070 But this one is actually running, 153 00:07:50,070 --> 00:07:52,440 and this is running off of the server, 154 00:07:52,440 --> 00:07:54,663 and it's running fairly well. 155 00:07:55,980 --> 00:07:56,813 Looks good. 156 00:07:59,070 --> 00:08:01,650 You might have saw that I need to install VMware Tools. 157 00:08:01,650 --> 00:08:03,780 That's important to install as well. 158 00:08:03,780 --> 00:08:04,680 But it runs well, 159 00:08:04,680 --> 00:08:06,750 and this is actually all coming over the network 160 00:08:06,750 --> 00:08:07,953 from the server. 161 00:08:09,570 --> 00:08:10,920 That is this guy right here. 162 00:08:10,920 --> 00:08:13,770 And you can see where I'm at, right here in this snapshot. 163 00:08:13,770 --> 00:08:16,113 You can run this from here as well, 164 00:08:17,310 --> 00:08:20,130 but that uses a lot of power on the server, 165 00:08:20,130 --> 00:08:23,160 so you really wanna do that from a client. 166 00:08:23,160 --> 00:08:23,993 There we have it. 167 00:08:23,993 --> 00:08:25,860 And like I say, this will throttle up and down, 168 00:08:25,860 --> 00:08:28,620 depending on what the virtual machine is doing 169 00:08:28,620 --> 00:08:29,853 and what it's using. 170 00:08:31,170 --> 00:08:33,030 It could be doing things behind the scenes, 171 00:08:33,030 --> 00:08:36,120 and that's gonna use more processing power on the server. 172 00:08:36,120 --> 00:08:39,240 But if we go back to our Task Manager on the client, 173 00:08:39,240 --> 00:08:41,280 there's virtually nothing being used. 174 00:08:41,280 --> 00:08:43,860 We're back down to that 4.7 gigabyte memory, 175 00:08:43,860 --> 00:08:45,870 which all the other apps I'm running, 176 00:08:45,870 --> 00:08:47,670 that's what's making up that usage, 177 00:08:47,670 --> 00:08:49,860 and the CPU's at 4%. 178 00:08:49,860 --> 00:08:53,250 So we're really not taxing our local CPU at our workstation 179 00:08:53,250 --> 00:08:57,453 because we're running these VMs off the server. 180 00:08:58,410 --> 00:09:00,600 That's the efficient way to do it. 181 00:09:00,600 --> 00:09:02,820 The server will handle these much better 182 00:09:02,820 --> 00:09:07,350 and make much more efficient usage of the CPU and RAM. 183 00:09:07,350 --> 00:09:10,830 In fact, in some cases, 184 00:09:10,830 --> 00:09:13,440 this CPU throttles all the way down to 1 gigahertz 185 00:09:13,440 --> 00:09:16,380 with this virtual machine running. 186 00:09:16,380 --> 00:09:18,060 So that's the way to do it. 187 00:09:18,060 --> 00:09:21,360 And this actually is the higher level. 188 00:09:21,360 --> 00:09:23,970 This one has the 8 gigabytes of RAM 189 00:09:23,970 --> 00:09:26,100 and the six CPU cores. 190 00:09:26,100 --> 00:09:26,933 We don't need that. 191 00:09:26,933 --> 00:09:30,720 We can completely reduce that for this virtual machine, 192 00:09:30,720 --> 00:09:32,520 and I probably will. 193 00:09:32,520 --> 00:09:34,830 So that's what you have to know though, 194 00:09:34,830 --> 00:09:35,760 you really have to know 195 00:09:35,760 --> 00:09:39,600 how to modify these virtual machines. 196 00:09:39,600 --> 00:09:41,010 If you're gonna run them locally, 197 00:09:41,010 --> 00:09:45,800 especially in VMware Workstation, Hyper-V, and VirtualBox, 198 00:09:47,760 --> 00:09:50,730 you have to be able to edit those virtual machine settings. 199 00:09:50,730 --> 00:09:53,730 And by the way, it has to be shut down. 200 00:09:53,730 --> 00:09:54,870 The guest has to be shut down 201 00:09:54,870 --> 00:09:57,690 before you can modify those settings 202 00:09:57,690 --> 00:10:00,720 and throttle those as necessary for the memory 203 00:10:00,720 --> 00:10:02,460 and for the CPU. 204 00:10:02,460 --> 00:10:04,053 So that's about it. 205 00:10:05,730 --> 00:10:07,740 Got lots of virtual machines here. 206 00:10:07,740 --> 00:10:09,990 We've got VMware Workstation running, 207 00:10:09,990 --> 00:10:12,510 and we've got our ESXi server running 208 00:10:12,510 --> 00:10:14,460 where I'm gonna be moving all these. 209 00:10:14,460 --> 00:10:16,980 And, in fact, this one came from here. 210 00:10:16,980 --> 00:10:21,360 I just uploaded it by going to Manage and Upload. 211 00:10:21,360 --> 00:10:23,640 You can also do an export, 212 00:10:23,640 --> 00:10:26,100 but you can upload directly to the server, 213 00:10:26,100 --> 00:10:27,270 and it didn't take long. 214 00:10:27,270 --> 00:10:28,920 It's pretty good stuff. 215 00:10:28,920 --> 00:10:31,410 Okay, so definitely check out some of these tools, 216 00:10:31,410 --> 00:10:36,410 VMware Workstation, Hyper-V for the client, and VirtualBox. 217 00:10:37,080 --> 00:10:39,540 And learn how they work a little bit 218 00:10:39,540 --> 00:10:41,730 and learn how to create virtual machines 219 00:10:41,730 --> 00:10:44,310 and edit those virtual machine settings, 220 00:10:44,310 --> 00:10:48,270 especially the memory, processors, and hard drive. 221 00:10:48,270 --> 00:10:50,760 And remember for the exams 222 00:10:50,760 --> 00:10:55,270 that the virtualization computer 223 00:10:56,310 --> 00:10:58,440 or virtualization server 224 00:10:58,440 --> 00:11:00,270 needs to have a pretty powerful processor 225 00:11:00,270 --> 00:11:03,510 but especially needs lots of memory 226 00:11:03,510 --> 00:11:08,040 'cause every VM that's running will use that amount 227 00:11:08,040 --> 00:11:12,360 that you've assigned from the physical RAM on that computer. 228 00:11:12,360 --> 00:11:15,630 All right, so that's about it for this video. 229 00:11:15,630 --> 00:11:17,043 I'm Dave, signing off.
