[SOLVED] Migrating a virtual machine from one server to another

AttempGame · Dec 1, 2022

Hello everyone, I want to migrate an entire virtual machine from one Proxmox VE server to another

On the server where the virtual machine is located, I execute the command
vzdump 106 --dumpdir /root --mode stop

after using scp

I am transferring this image to a server where I want to deploy a copy of this virtual machine

scp /root/vzdump-qemu-106-2022_11_30-21_56_04.vma root@0.0.0.0:/root/

Next on the server where I want to restore the copy I execute

qmrestore /var/lib/vz/dump/vzdump-qemu-106-2022_12_01-01_42_48.vma 103

root@Debian-1101-bullseye-amd64-base ~ # qmrestore /var/lib/vz/dump/vzdump-qemu-106-2022_12_01-01_42_48.vma 103
restore vma archive: vma extract -v -r /var/tmp/vzdumptmp15808.fifo /var/lib/vz/dump/vzdump-qemu-106-2022_12_01-01_42_48.vma /var/tmp/vzdumptmp15808
CFG: size: 433 name: qemu-server.conf
CTIME: Wed Nov 30 23:42:48 2022
vma archive contains no image data
rescan volumes...

I get this error, I have completely cloned the virtual machine, but there is no virtual machine disk image from which it should be launched

what does "qm config 106" show on source server? what does the vzdump log look like? Is this VM using pass-through disks perhaps?

you only have one disk and its excluded from backup. The error message correctly reports that no actual image is found in the archive.

size of the archive is another clue.

How can I make a backup so that it includes image?

remove the the backup=0 attribute.

Code:

qm set 106 --scsi0 local-lvm:vm-106-disk-0,size=32G,ssd=1

Go to "YourVM -> Hardware -> select your virtual disk -> Edit" and then set the "Backup" checkbox.

most likely the backup flag is not active on the VM's drive(s) so the backup only contains the configuration. You can Edit the drive in the VM's Hardware tab and enable the backup flag in the Advanced Options.
