Hi Mat, each VM in proxmox is deployed with specific virtualization CPU type. By default pve uses KVM64 as CPU type. This cpu type ensures that the VM runs on almost all hypervisor hosts. However, this KVM64 type is not optimal from a performance point of view. On the other hand, as KVM64 runs...

Oh my god. That solved my issue. I have no idea how this configuration got lost. Thank you so much! Best Matthias

Hello everyone! I recently upgraded from pve 6 to 7 and moved my cluster to a new network. Unfortunately the remote vnc console is broken now. I cannot access the "Console" of a VM from one node if the VM is not running locally. If the VM is running on the same node, the vnc connection...

I finally found out why the backup crashed the VMs. TLDR; The KVM64 default cpu type proxmox provisions seems to not support important co-processors that qemu uses to speed up the backup. After changing the CPU type for all VMs to the "greater common denominator" of all pve nodes (in my case...

Hey there, I encountered a strange problem the other day. So first let me describe our setup. We use proxmox for VM and container hosting. Up until now, we used local storage (ZFS) in each of our hypervisors. As you know there are many drawbacks with only local storage. We finally wanted to have...
