7.4 vs 7.3 - Stability issues on new version.

[freebee]

Hi.
I installed 7.4 and all updates are installed.
Some problems were found.
Windows virtual machines don´t start anymore when using hv-tlbflush.
Today I experienced a Windows 2012r2 vm freeze (crtl+alt+del don´t give me a prompt to log in but the mouse was working ok). Qemu Agent stopped. Resetting the machine makes it work again. On local logs (events) nothing strange happened.
The same machine worked ok on the second node (7.3) for one week without problems and is the same machine (cpu, ram memory and etc).

Have some way to downgrade the PvE?

No. But you could try to boot an older kernel or even try the new 6.2 opt-in kernel.

I updated it to 6.2. My impression is a speed-up to the VM.
The hv-tlbflush back to work.
Tomorrow I will see how is working when will be busy. If everything ok, at the end of the week I will give the feedback.

Today the same problem. But looking in to events i found the problem.
Event 129 or is the same here https://forum.proxmox.com/threads/w...csi-warning-129-locking-up-data-drive.121936/
Possible Bug from qemu ?.
