I've been using this command to migrate VMs between nodes but today we upgraded nodes to the latest version and the command no longer works:
Code: 
vzdump $vm --stdout | ssh $host@$ip qmrestore - $vm --storage local --force

INFO: sending archive to stdout
INFO: starting kvm to execute backup task
ERROR: couldn't determine format and compression type


Is there anything wrong with the command?

no, this is a bug. fix is already on the way ;)
 
Hi.

Is there any workaround for it ?

I did HDD upgrade of two servers with fresh install of PROXMOX and end up with running hypervisors but without VMs. Unable to Restore backups from WebUI, same error "TASK ERROR: ERROR: couldn't determine format and compression type".

qemu-server 6.2-1 contains the fix. as a workaround you can restore from a file instead of stdin.
 
I did qmrestore from file (*.vma.lzo) and Restore via PROXMOX WebUI, both doesn't work, same error.

apt update; apt upgrade doesn't show qemu-server 6.2-1. And can't find it on pve-no-subscription or pvetest repo (http://download.proxmox.com/debian/pve/dists/buster/pve-no-subscription/binary-amd64/) either.

Did try "apt install qemu-server=6.1-19" (downgrade to previous version - it didn't want downgrade nothing more), unsuccessfully. Downgrade to qemu-server=6.1-14 have unmet dependencies.
 
@fabian: I found your patch, I apply it, but still does not work.

behavior of the original PVE/QemuServer.pm (version 6.1-20):

Code: 
# qmrestore /var/lib/vz/dump/vzdump-qemu-10202002_mat_20200505-201556.vma.lzo 10202002 --storage local --force
ERROR: couldn't determine format and compression type
# cat /var/lib/vz/dump/vzdump-qemu-10202002_mat_20200505-201556.vma.lzo |qmrestore - 10202002 --storage local --force
ERROR: couldn't determine format and compression type

and after apply your patch:

Code: 
# qmrestore /var/lib/vz/dump/vzdump-qemu-10202002_mat_20200505-201556.vma.lzo 10202002 --storage local --force
ERROR: couldn't determine format and compression type
# cat /var/lib/vz/dump/vzdump-qemu-10202002_mat_20200505-201556.vma.lzo |qmrestore - 10202002 --storage local --force
restore vma archive: vma extract -v -r /var/tmp/vzdumptmp32530.fifo - /var/tmp/vzdumptmp32530
command 'set -o pipefail && vma extract -v -r /var/tmp/vzdumptmp32530.fifo - /var/tmp/vzdumptmp32530' failed: got timeout

It look like it is not only "qmrestore from STDIN" problem, but more general. I will bump new post.

I am still without VMs and need any workaround.

obviously restoring backups in general works - it was only STDIN that was broken, hence only that was fixed in my patch. see my reply to the other thread for your other issue!
