Hi,
currently are our VMs network dualstack mainly. Only very small number of them is ipv6 only. The problem is currently detected on the dualstack VMs on the PVE 8.4.
When doing manual offline migration (gui or ha-manager), some migrated VM's...
Busy database with huge number of the cpu cores? Solution:
1] disable HT
or
2] don't overallocate nonHT cores to VM+PVE
The HT cores aren't for busy/fast/etc workloads, but for idle/low workloads mainly (so you can overallocate low power VMs).
