Just an FYI for those migrating from VMware to PVE and have Veeam. The latest version that came out this week, 13.1 has a very nice new feature. During a restore of the VM to Proxmox, it will automatically inject the VirtIO drivers. It will set the SCSI Controller to VirtIO SCSI Single, set the disk(s) to SCSI and also set the NIC to Virtio. The VM boots up correctly the first time with no driver injection or other hoops to jump through. The VM will reboot a few times as drivers are loaded, but this feature makes the migration even easier. QEMU Guest Agent is also installed and enabled. Also 13.1 introduce Replication of VM's and supports setting the vlan tag during restore.
