盘符切换（盘已满）​

在解压 android 源码过程中，发现 windows 宿主机的 C 盘空间急剧减少，说明当时安装 virtualbox 的默认位置在 C 盘，但是我的 C 盘只有 200 多 G。

查询了一点文章后，发现只要把vdi文件转移即可。

于是我找到了 C 盘目录下的 virtualbox 文件夹，然后将它整体移到 D 盘，并且修改 virtualbox 中所有和路径相关的属性。

✅ 分辨率切换​

在虚拟机内，点击设备 | 安装增强功能，装完之后，在桌面上会有个挂载，实际上是在/media/mark/下。

然后进入文件夹，sudo sh VBoxLinuxAdditions.run，就能自动安装相关增强工具，接着在虚拟机右上角点击重启即可。

之后虚拟机的界面就可以手动拉升了，并且不损失分辨率，否则基于系统内置的显示，只可以缩放，会很模糊。

✅ Fixed: Develop on a Linux computer that supports VT-x or SVM​

Solution: 关闭虚拟机，然后启用 virtualbox 里的虚拟选项即可：

Evidence: 打开 Android studio 里的 avd，已经不提示虚拟化报错了：

You should download one emulator first, such as in the android studio AVD.

ProbeKVM: This user doesn\'t have permissions to use KVM (/dev/kvm).
The KVM line in /etc/group is: [kvm:x:998:mark]

If the current user has KVM permissions,
the KVM line in /etc/group should end with ":" followed by your username.

If we see LINE_NOT_FOUND, the kvm group may need to be created along with permissions:
    sudo groupadd -r kvm
    # Then ensure /lib/udev/rules.d/50-udev-default.rules contains something like:
    # KERNEL=="kvm", GROUP="kvm", MODE="0660"
    # and then run:
    sudo gpasswd -a $USER kvm

If we see kvm:... but no username at the end, running the following command may allow KVM access:
    sudo gpasswd -a $USER kvm

You may need to log out and back in for changes to take effect.
