| + | |
| + | qm set 1000 --boot c --bootdisk scsi0 |
| + | qm set 1000 --serial0 socket --vga serial0 |

| + | # please utilize the 'source' or 'source-directory' directives to do |
| + | # so. |
| + | # PVE will preserve these directives, but will NOT read its network |

| + | # the PVE managed interfaces into external files! |
