Good evening,
we experience problems when migrating to hosts between a host with CPU:
to a host with CPU:
No problem in the opposite direction.
On both host we have the same PVE version:
Following other posts, we tried with other kernels (on older server, the one with Xeon 6326) without success:
An error we noticed is:
With Linux Debian VMs, migration job completes correctly, but the VM has CPU at 100% after that and is unavailbale.
With Windows VMS, migration job completes correctly, but Widows detects some problems and restart the guest OS.
On older host cat /proc/cpuinfo shows tsc_scaling paramether is not present, but on newer one it is.
Any ideas?
Best regards,
Matteo
