disk storage​

500G. Since the size of AOSP is about more than 200G, so 500G, which is double, is reasonable for that need.

⚠️ However, we'd better pre-allocate the disk space for speed, and if we set it later, the machine transfer time would be costly!

Update at 2022-01-24:

picture 2

You see, the 500G pre-allocated disk takes up more than 600G, when I just download the AOSP mirror, how could it be?

The answer becomes clear: The so-called pre-allocated disk size doesn't mean the full size of the disk to be used, but to be only the core running disk size of virtual machine, so that it's unnecessary to pre-allocate a huge size (such as 500G) for it!!!

Hence, I would just delete the mirror, and re-install one, with no option for pre-allocated size, since I remembered on stackoverflow or anywhere other it said there has no or slight efficiency effect on whether we enable or disable the option pre-allocate.

⚠️ And after I just did nothing to the vmware settings (i.e. 20Gb for vmware), and tried to install the AOSP, it warns me that the disk space is not enough. So We still need to allocate a big enough disk space, but not a pre-allocated one!

FIXME: Space not enough!

但是就很奇怪，因为我重新分配过磁盘大小，理论上来说应该是够的：

算了，暂时没时间研究这个问题了，我先同步再创建一个更大的新的镜像试试吧，顺带验证默认的 shell 支持不支持# xxx和# !IMPORTANT xxx.

disk type​

I searched the difference between different bus types, and it seems that it's better for me to use the default choice of scsi.

vmware best practice​

retina solution​

!!!tip 1. 有些帖子说要安装vmware tools，但我看我的 vmware 里应该是已经有了，因为当我想点那个按钮的时候，显示的是reinstall vmware tools，此外，这个按钮必须是启动了虚拟机后才会可点，而且启动后也不一定可点…… 2. 忘了。。

First, check the use full solution for retina display, otherwise the screen is 模糊的（像素化）了。 picture 2

However, the cost is that all the text or icons then look too tiny, so that can't be used.

The solution is to set the solution of the system and the display scale:

picture 3

Then the screen looks real!

But there is still a drawback, that is each time switch the view, the scale would goes back. To solve this, if the virtual machine is a Mac, then adjust the solution via:

// mac terminal
sudo defaults write /Library/Preferences/com.apple.windowserver DisplaysolutionEnabled -bool true

However, if it's a ubuntu, I don't know how to realize it now. PR: ubuntu solution.

At last, the retina solution under full-screen mode:

explain why ubuntu conflicts with the retina since it's not for high-dpi screen.

it's useful when start a mac vmware on a mac.

config keyboards​

1. ✨ mac host key​

We can specify whether to enable mac host keyboard shortcuts. picture 1

However, before we do that, we should consider about it carefully that should you sacrifice your ubuntu experience for the mac multi-tasks or to sacrifice your mac experience for a pure ubuntu use.

Although there is one option for us to specify which command key for ubuntu, I failed to let it work.

A possible resolution is to config file place: ~/.vmware/preference.ini, see: 1. not found config file: sanbarrow.com 2. not found config file: How to change or disable hotkey for VMware Player? - Super User

However(updated@2022-02-12):

不需要替换文件！（也很难找到）

只要在 vmware 的键盘中，添加一个 Command -> Ctrl 的映射即可！

然后一切都是如此的丝滑！

妙啊！（折磨了我一个月了 😢）

2. copy paste​

!!!warning OUTDATED: use command -> ctrl map ! Since the copy paste in linux, are default triggered by the combined key of ctrl + shift, so we can specify the key map:

<img alt="picture 2" src="https://mark-vue-oss.oss-cn-hangzhou.aliyuncs.com/notes-1642344159090-57a3cfb0715bd2f3e9bdc354eb4e34a77b668719d9b0a1084423e9823b10c794.png" />

And in fact, since the default select / copy / paste actions in ubuntu is triggered by `ctrl` by default, I can accept to use `ctrl A/C/V` in vm to avoid annoying different problems caused by command.

Only need to map Command to Ctrl! (updated@2022-02-12)

vpn proxy​

In normal circumstance, the net is okay.

However, since I use clashx, I can visit outer net in my mac, which is a problem that the virtual machine can not share with the foreign net with the host.

1. know what's your ip and vpn port of host machine​

2. ensure the net type in vm​

3. specify the vpn manually in vm​

share files between host(mac) and guest(ubuntu)​

BEST-PRACTICE: use vmhgfs-fuse and auto-complete supported​

sudo mkdir -p /mnt/hgfs
sudo vmhgfs-fuse .host:/ /mnt/hgfs -o subtype=vmhgfs-fuse,allow_other

ref:

resolution 1. use /mnt/~​

there are a few of disadvantages:

  1. Every time, it needs to re-activate using sudo vmhgfs-fuse .host:/ /mnt/ (although we can config it in the zsh/bash rc file)
  2. It only supports to fetch the host files within the vmware, which means it's uneasy to directly operate on host (not equally designed, or maybe there is another way)
  3. FIXME: When using in the vmware, I found there is no auto-completion for files on host.

mount host user folder to guest (transfer file from guest to host)​

After a little of search, I found the easiest way is:

sudo vmhgfs-fuse .host:/ /mnt/

After this, there is one directory (my mac user folder mark) merging up under the ubuntu /mnt folder.

And then I can easily to transfer files from vmware to mac.

ref:

umount user folder in guest​

sudo umount /mnt

Then the folders under /mnt would go.

vmware​

感觉这个官方解决方案 "An error occurred while consolidating disks" when deleting one or more snapshots or consolidate disks (2150414) 是合适的，就是不知道具体怎么弄：

resolution 1. Free up space on the datastore(s) holding the virtual machine configuration files and virtual disks.

resolution 2. Alternatively, increase the size of the datastore on which the virtual machine is located. For more information, see the vSphere Storage guide.

run emulator on ubuntu vmware​

FIXME: unable to run emulator after building AOSP​

A possible resolution may be to lunch full-eng && m which is suggested in Unable to run emulator after building AOSP, and now I am testing this solution.

ref:

 emulator -partition-size XXX # XXX is the desired size(MB)

However, maybe my system is limited since when the size exceeds 2048MB, another problem would arise up....
