It would be great to have a "register VM" option - like VMware feature. It's very usefull to copy all VM folder, register it and have a working VM. Is there any future planning to introduce that feature ath Proxmox?
KVM just works different and has a different approach. I needed to get used to it as well.
Technically VMs are started with parameters and in case of PVE these are pulled from a central config store. So the only thing you would really need are the disks...
Unusual for someone who uses VMware. I have to admit...
