Bug 2026599

Hi Fabian

Could you please share the windows guests you want QE to test?

Windows 10 and (not yet available on CNV) 11

Test wsl2 on rhel-av 8.4.z, wsl2 and win10 guest work well.

Test environment:
hosts: kernel-4.18.0-305.25.1.el8_4.x86_64 & qemu-kvm-5.2.0-16.module+el8.4.0+13460+2e130eec.13.x86_64
cpu of src and dst host: AMD EPYC 7313 16-Core Processor
guest: latest win10 guest, fedora-33 as wsl2


Test scenarios:
1. ping-pong migration with win10 + wsl2;
2. ping-pong migration with win10(running netperf) + wsl2(running stress);


Test result:
Migration succeeds, Win10 and wsl2 works well before/after migration, cpu usage is normal in whole migration process.
