I have 7 nodes in my cluster and 6 of them are running older Intel CPUs, with each node having 2 sockets. The problem is the 1 node that I have that is running an AMD CPU. This node will not start a VM unless the processor type is set to max or to host. These of course can cause issues if the VM migrates as part of HA. I was able to a VM to start using kvm32 but I know the node has 64bit CPUs, they are listed on the Proxmox WebUI as Quad-Core AMD Opteron Processor 2356. I have the latest packages and I have hardware virtualization turned on in the BIOS. I also noticed that if I turn off hardware virtualization in the VM settings it will boot with the default processor type.
[SOLVED] Issue starting VM with default processor Type
- Thread starter Astraea
- Start date
Just updated to the latest version of Proxmox VE and still getting this error:
Here is the VM configuration, it is a very basic VM with just enough to see if it will start on the node:
Code:
kvm: warning: host doesn't support requested feature: CPUID.80000001H:EDX.nx [bit 20]
kvm: Host doesn't support requested features
