Debian 9 virtual machine does not start in xcp-ng 8.3
-
Good afternoon, I just upgraded from xcp-ng 8.1 to 8.2 and then to 8.3. I have a virtual machine running Debian 9 that stopped working. It displays grub upon startup, but when it starts loading, it pauses and immediately shuts down. I downloaded the installer, and it does exactly the same thing. I tried older versions and it works fine. It seems to be related to the 4.9.0-11 kernel version. Do you know if this is a known issue?
Regards

Hi,
Are you in PV or HVM mode?

How are you @olivierlambert ? He's at HVM.

Update: If I change the vCPU configuration to 1 socket with 4 cores per socket the VM starts correctly
-
OK so potentially a vCPU topology issue
