VM die when i try move disk and change format

[dg_]

Hello,

I am trying to move from qcow2 to vmdk with this command when vm is running:

root@pve1:~# time qm move_disk 11111111 scsi1 SSD_LOCAL -format vmdk -delete 1
create full clone of drive scsi1 (SSD_PREMIUM:11111111/vm-11111111-disk-2.qcow2)
Formatting '/mnt/ssd/images/11111111/vm-11111111-disk-1.vmdk', fmt=vmdk size=53687091200 compat6=off
drive mirror is starting (scanning bitmap) : this step can take some minutes/hours, depend of disk size and storage speed
storage migration failed: mirroring error: VM 11111111 qmp command 'drive-mirror' failed - client closed connection

real 0m0.551s
user 0m0.440s
sys 0m0.080s
root@pve1:~#

After this error, vm die and if i execute again with vm stopped, command works.

You can't change the format in an running VM.
