English-> Ubuntu Server(mimimized) -> Skip Ubuntu Pro -> Install OpenSSH server.

sudo apt update
sudo apt install -y vim sddm libvirt-daemon qemu libvirt-daemon-system-systemd libvirt-daemon-driver-qemu libvirt-daemon-system libvirt0

Examine the version:

$ qemu-system-x86_64 --version
QEMU emulator version 6.2.0 (Debian 1:6.2+dfsg-2ubuntu6.6)

# update-initramfs -u -k all
# sudo reboot

Use mate for desktop session:

$ sudo apt install -y mate

libvirt hook should be the same.

sddm autologin :

# mkdir -p /etc/sddm.conf.d
# vim /etc/sddm.conf.d/autologin.conf

4. issue

On rocky linux, we got following issues:

[idv@rockyIDV ~]$ ./test_10thFV_win10.sh 
2023-03-28T05:53:46.994085Z qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,x-igd-gms=2,id=hostdev0,bus=pci.0,addr=2,rombar=0,x-igd-opregion=on: IGD device 0000:00:02.0 does not support OpRegion access,legacy mode disabled

Now change back to Ubuntu22.04.

Also spice-server is removed for rhel9, so got lots of time for building spice related libs.

Install virt-io drivers:

Then the amd gpu:

Get the driver:

Copy the file into :

Then add it into shutdown items:

Edit its sequence:

eject script:

Function Check-RunAsAdministrator()
{
  #Get current user context
  $CurrentUser = New-Object Security.Principal.WindowsPrincipal $([Security.Principal.WindowsIdentity]::GetCurrent())
  
  #Check user is running the script is member of Administrator Group
  if($CurrentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator))
  {
       Write-host "Script is running with Administrator privileges!"
  }
  else
    {
       #Create a new Elevated process to Start PowerShell
       $ElevatedProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";
 
       # Specify the current script path and name as a parameter
       $ElevatedProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
 
       #Set the Process to elevated
       $ElevatedProcess.Verb = "runas"
 
       #Start the new elevated process
       [System.Diagnostics.Process]::Start($ElevatedProcess)
 
       #Exit from the current, unelevated, process
       Exit
 
    }
}
 
#Check Script is running with Elevated Privileges
Check-RunAsAdministrator
 
#Place your script here.
     $deviceName="AMD Radeon(TM) Graphics"
foreach ($dev in (Get-PnpDevice | Where-Object{$_.Name -eq $deviceName})) {
  &"pnputil" /remove-device $dev.InstanceId 
}
# sleep for 8 seconds
Start-Sleep -Seconds 8

RecoveryFromUEFI

Use archlinux installation disk for entering the command line, then:

mkdir /mnt/arch
mount -t auto /dev/sda2 /mnt/arch
mount -t auto /dev/sda1 /mnt/arch/boot/
arch-chroot /mnt/arch

Re-install grub:

grub-install --efi-directory=/boot/efi --target=x86_64-efi /dev/sda

Then reboot the machine we could see the archlinux reback again.
