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

Server from where I want to make a copy:

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