I have a linux based vm that was delivered as an OVA. I installed this on my Vmware server a few years ago, but I'm looking to migrate it to our Proxmox cluster. The only issue I have is that I cannot install the QEMU agent as I don't have root access to this little appliance vm. I'm not too concerned with the possible performance hit, but I'm curious to what other hard issues I might have. Would I still be able to do snapshots for backups etc? Thanks.
