We have installed a number of PROXMOX Hosts on our VSPHERE Center. On one System we encountered following problem:
1. VSPHERE on Bare Metal Intel(R) Xeon(R) Gold 6342 CPU (48 Cores)
2. PROXMOX 7.3-3 (Linux 5.15.74-1-pve #1 SMP PVE 5.15.74-1) on Debian 11
3. Open-vmware-tools installed Debian / Proxmox Host
If we configure 4 CPU in VMware for this PROXMOX Host and Starting the SNAPSHOT in VSPHERE, then
we can't ping the Proxmox Host IP anymore and after the Snapshot is created (~5 Min) then the
PROXMOX Host does a full reboot / restart. Nothing is written to syslog or anywhere else.
If we configure 16 CPU in VMware everything is working as expected.
We have not tried a number of CPUS between 4 and 16 yet but another PROXMOX Host (7.4) is also working on 12 CPU.
It seems that the pve-kernel encounters that issue, because a simple Debian 11 system with Open-vmware-tools will also work on 1 CPU correctly.
Anybody any hint?
