VirtualBox 7.0.4安装macOS High Sierra
硬件要求
Intel E3-1230 v3 可以成功安装， AMD Ryzen 5900 CPU 在 Linux 系统上，需要配置 CPU 模仿 Intel CPU 的特性。并且 CPU 部分，不要启用 嵌套VT-x/AMD-V 。
生成系统安装镜像
在 macOS (实验使用的系统是 macOS Big Sur (11.7.1))系统上，执行如下命令，生成系统安装镜像

Windows 10系统VirtualBox无法进入系统，日志报错“HM: HMR3Init: Attempting fall back to NEM: VT-x is not available”
在Windows 10上使用 Linux 子系统的时候，无法成功启用。根据官方文档 旧版 WSL 的手动安装步骤 之后，依旧没效果，反倒是VirtualBox无法进入系统了。
观察日志，报错信息如下：
Intel CPU
|
1 2 |
{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work... |
AMD CPU
|
1 2 |
{timestamp} HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available {timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work... |
解决方案如下：
1.使用管理员启动命令行.
2. 执行如下命令:
|
1 |
bcdedit /set hypervisorlaunchtype off |
某些电脑需要额外执行如下命令:
|
1 |
DISM /Online /Disable-Feature:Microsoft-Hyper-V |
3. 重启电脑

增加VBox显存到256M
Virtual Box supports up to 256 MB of video RAM. This can not be set using the slider of the Virtual Box Manager.
To make full use of all supported memory we can issue the following command in a terminal:
|
1 |
$ VBoxManage modifyvm "Name of VM" --vram 256 |
Before we change settings such as the video RAM a pre-existing virtual machine has to be shut down.
Note that for 3D video hardware acceleration from the guest addition’s video driver the physical RAM of the host graphics card will be passed through. The video RAM settings of the virtual machine will not affect this.

How to mount Virtualbox drive image(vdi) on Ubuntu 16.10/20.04
This tutorial will explain How to mount Virtualbox drive image(.vdi) on Ubuntu 16.10.First we need to install QEMU tools using the following command
sudo apt-get install qemu-kvm
Now we need to load the network block device (nbd) module using the following command
sudo modprobe nbd
run qemu-nbd, which is a user space loopback block device server for QEMU-supported disk images.
qemu-nbd -c /dev/nbd0 [vdi-file]
Note:- vdi-file :- Your vdi file location for example /home/test/ubuntu.vdi
Example
qemu-nbd -c /dev/nbd0 /home/test/ubuntu.vdi
You can check the partitions in the image using the following command
sudo fdisk -l /dev/nbd0
The above command will check the entire image as a block device named /dev/nbd0, and the partitions within it as subdevices. For example, the first partition in the image will appear as /dev/nbd0p1.
If you want to mount the first partition use the following command
sudo mount /dev/nbd0p1 /mnt
Now you can check all the contents of /mnt partition and copy all the required files.
After completing your work you can unmount the partition using the following command
sudo umount /mnt
Shutdown nbd services using the following command
sudo qemu-nbd -d /dev/nbd0
