Windows VM extremely slow

[trigg3r]

I just updated PVE 8 and after rebooting my two Windows VMs (Windows10 and Windows Server 2019) are stuck (it's been 30 minutes and I'm still waiting to see the login screen appear on the console ...). These are machines configured following best practices (VirtIO driver, host CPU, WriteBack cache) that until this morning were working properly ...

In server Summary the monitoring data does not indicate any overload.

Does anyone have an idea what could have happened?

There are too little information to have possibility to help you, please start to post atleast full vm configuration:

qm config <vmid>

and the virtio drivers version used.

And since seems a regression after update, you checked also system logs?
