1 00:00:01,370 --> 00:00:11,570 That we create a machine we need to give IT resources in order to run our Sebille memory story and all 2 00:00:11,570 --> 00:00:14,220 other parts of our computer. 3 00:00:14,880 --> 00:00:22,360 That an operating system relies on and to give the resources to our guest machine. 4 00:00:22,780 --> 00:00:31,150 We need to bake or otherwise designate resources on the host your whole system has one or more Scipio's 5 00:00:31,230 --> 00:00:39,790 on processors that take care of running software and doing the math that makes almost everything on 6 00:00:39,790 --> 00:00:41,320 the system work. 7 00:00:41,670 --> 00:00:49,200 But we create a virtual machine we need to tell what toolbox home and the processor the guest operating 8 00:00:49,200 --> 00:00:52,400 system has to do. 9 00:00:52,500 --> 00:00:58,600 This does not need to exactly match what the whole system has. 10 00:00:58,610 --> 00:01:04,830 In fact it's usually a good idea to give the guest fewer places than the host has. 11 00:01:05,880 --> 00:01:13,530 Telling a guest that it has set the number up to secert does roadblock or persists from the rest of 12 00:01:13,530 --> 00:01:14,570 the system. 13 00:01:16,190 --> 00:01:22,440 The virtual box that we're scared of sending commands from the guest to the processor as they need to 14 00:01:22,440 --> 00:01:33,600 be executed on an older horse that don't support what Tula's Ishan box will Mullett possessor. 15 00:01:33,660 --> 00:01:41,880 Instead it will appear to the first operating system that it has given amount of persisting resources. 16 00:01:43,100 --> 00:01:47,430 Though that's not strictly strictly true. 17 00:01:47,470 --> 00:01:54,960 It's really competing with the host and other guest for the time running instructions on the process. 18 00:01:55,740 --> 00:02:05,320 Typically you can get by just fine with one processor but if you are a guest will be doing more combinational 19 00:02:05,430 --> 00:02:09,340 interesting things you can add more processor. 20 00:02:09,360 --> 00:02:10,730 If they are available 21 00:02:13,290 --> 00:02:21,450 allocating memory to against them all the memory against CVS but the memory is not taken up all at once 22 00:02:21,510 --> 00:02:28,410 on the host get started using them the host memory gets taken up. 23 00:02:28,450 --> 00:02:36,680 And as things go out of memory on our guest the host of memory is released as well. 24 00:02:36,910 --> 00:02:44,020 So the number that we set for the memory I guess to the present the large amount of memory that it can 25 00:02:44,020 --> 00:02:52,570 take on the host most of the time guest needs storage in order to install them running the system or 26 00:02:52,720 --> 00:02:58,260 work with data you really it will create a virtual hard drive. 27 00:02:59,380 --> 00:03:03,930 As a file on the host and for that we have two options. 28 00:03:05,280 --> 00:03:06,210 Two options. 29 00:03:06,220 --> 00:03:14,250 We can create a dynamic image on a fixed image file both title file provides a hard disk Unforgiven 30 00:03:14,380 --> 00:03:17,730 size to a great guest operating system. 31 00:03:17,920 --> 00:03:27,620 And the difference lies in hold the file is managed on the host or that image only takes up space on 32 00:03:27,620 --> 00:03:37,040 the host as data is added to it and a fixed image file takes all of the space for the guest hard drive 33 00:03:37,580 --> 00:03:39,760 right from the beginning. 34 00:03:39,830 --> 00:03:44,720 Reading and writing data from the fix we need is a little bit faster. 35 00:03:44,990 --> 00:03:50,540 But to fix the image takes up a lot of space but it helps you to 36 00:03:54,450 --> 00:03:58,210 conserve space on the host. 37 00:03:58,230 --> 00:04:07,170 It does not take up tens or hundreds of gigabyte to store a mostly empty guest hard drive for networking. 38 00:04:08,380 --> 00:04:17,980 Video Audio and chipset virtual boss creates a series of emulated devices devices which looks to the 39 00:04:17,980 --> 00:04:24,890 guest as though they are real devices but which in reality are virtual. 40 00:04:26,110 --> 00:04:33,430 What you want takes the information sent to these little devices and translates it to the host computer. 41 00:04:35,240 --> 00:04:36,120 Real hard. 42 00:04:36,170 --> 00:04:43,170 How did the devices are pretty generic and most of us just don't have built in support for them. 43 00:04:44,310 --> 00:04:51,070 Usually we don't need special drivers or anything to get them working on a common labelling system. 44 00:04:53,910 --> 00:04:55,490 As you will see later on. 45 00:04:55,530 --> 00:04:59,450 A big exception here is the video device. 46 00:04:59,790 --> 00:05:08,310 The vulnerable toolbar use a very generic device and many object system like a fallback or the lowest 47 00:05:08,310 --> 00:05:10,990 common denominator. 48 00:05:11,220 --> 00:05:17,690 So we need to install a driver with a guest and the Shanes in order to get a better experience. 49 00:05:18,760 --> 00:05:22,140 More reservation's options and so on. 50 00:05:22,160 --> 00:05:25,140 I look at the resources between the host and Gerster machine. 51 00:05:25,150 --> 00:05:34,730 Is all these are Bello's you need to make sure you give your guests enough resources but not at the 52 00:05:34,730 --> 00:05:39,950 expense of the host usability or stability. 53 00:05:39,950 --> 00:05:49,000 Taking too much processor time are limited and can slow down the host to the point of load running very 54 00:05:49,000 --> 00:05:55,570 well and piggin too much disk space can cause problem when the host needs to see files. 55 00:05:55,580 --> 00:05:56,330 Two days.
