Use diskutil for Change the EFI partition:

/images/2023_04_12_10_41_07_510x533.jpg

Copy from iso’s EFI to disk’s EFI:

% cp -r /Volumes/EFI/EFI /Volumes/EFI\ 1/
% sudo sync
% sudo shutdown -h now

Enable ssh:

Then we could use ssh via:

# ssh test@192.168.1.129

System Installation

Ubuntu 22.04.2 iso, Install with HWE Kernel Selected.
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

System Configuration

Kernel and modules:

# sudo vim /etc/default/grub
......
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on intel_iommu=pt kvm.ignore_msrs=1"
......
# sudo update-grub2
# sudo vim /etc/initramfs-tools/modules
......
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
# update-initramfs -u -k all
# sudo reboot

Use mate for desktop session:

$ sudo apt install -y mate

libvirt hook should be the same.
