Basic System Configuration Steps

Install some necessary packages:

$ sudo vi /etc/apt/sources.list.d/ubuntu.sources
$ sudo apt update -y
$ sudo apt upgrade -y
$ sudo apt install -y virt-manager vim ovmf
$ qemu-system-x86_64 --version
QEMU emulator version 8.2.2 (Debian 1:8.2.2+ds-0ubuntu1)
Copyright (c) 2003-2023 Fabrice Bellard and the QEMU Project developers
$ sudo reboot

OS infos:

idv@idv-P860:~$ uname -a
Linux idv-P860 6.8.0-40-generic #40-Ubuntu SMP PREEMPT_DYNAMIC Fri Jul  5 10:34:03 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
idv@idv-P860:~$ cat /etc/issue
Ubuntu 24.04 LTS \n \l

Unset some configuration under gnome:

set Autologin
auto sleep, off
auto lock , off

Virtualization Steps

Configure as following steps:

# vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=pt amd_iommu=on initcall_blacklist=sysfb_init pcie_acs_override=downstream,multifunction"
# vim /etc/initramfs-tools/modules 
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
# vim /etc/modprobe.d/vfio.conf
options vfio-pci ids=1002:6611,1002:aab0
options vfio-pci disable_idle_d3=1
# update-initramfs -u -k all && update-grub2 && reboot

VM Preparation(Win7-bios-q35)

Image creation:

# qemu-img create -f qcow2 win7_bios_q35.qcow2 60G
Formatting 'win7_bios_q35.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=64424509440 lazy_refcounts=off refcount_bits=16

Install windows 7 as the default configuration.

VM Preparation(Win7-uefi-q35)

Create the disk via:

# qemu-img create -f qcow2 win7_uefi_q35.qcow2 60G
Formatting 'win7_uefi_q35.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=64424509440 lazy_refcounts=off refcount_bits=16

Change the boot configuration:

Using Win7_Hygon.iso we got abolve result.

change to another iso, en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso:

libvirt hooks

After added vfio hooks, the command is listed as:
