Windows server 2025 VM's stuk after some hours/days after migrating fro m xenserver to xcp-ng

rniesen

Hello,

I migrated an older xenserver 8.2 cu1 to xcp-ng 8.3.
This was because we replaced the old server with a new HP ML350 Gen 11 with Xeon sivler 4510 CPU.

We see that the vm's are unrespnive sometime.
Sometime they react again after a while, sometime I can do a reboot but sometime tehy hang 100%

I dit already past week an update of xcp-ng (yum update).

I know there si a new firmware release wich I will try these weekend.
But does anyone knows why we have this issu on this new hardware.

What is the corret settings for an HP ML350 server?
Is there still an issue with C-states?

Or must I create a new vm and attached the old disk to the new vm's?

We use the latest xcp-ng pv singed drivers.

I also will start an VM wiht a ubuntu live and see if that will stuck to.

All imput are welcome.

Kr,

Roel Niesen

Hi,

Could you check the VM's Viridian settings from the host:

xe vm-param-get uuid=... param-name=platform

Followed by checking the Windows BCDEDIT settings:

bcdedit /enum all
