Hi,
I was successful in upgrading my system from 5.4 to 6.1 today without any major issues. However, after a reboot post-upgrade the Windows KVM guests seem to be slower than on the previous version.
The KVM guests have the drivers installed from virtio-win-0.1.173.iso - which are believe are the latest. All settings are as recommended in the wiki article as well so not sure why suddenly the performance dropped.
is there anything under the new KVM/QEMU that needs to be done to restore the performance?
I noticed pve6 added some new 'performance tweaks' for windows hosts but this seems to be the opposite of expected.
