No more acces to manager VM after changing ovirtmgmt VLAN settings

Hi,

I did a terrible mistake : I wanted to make some tests on VLAN, but I used the wrong interface to test it : ovirtmgmt

Since then I can't access anymore to the Manager VM.

It seems the VM can't start anymore, with vdsClient -s 0, I can see it with "Status = Down" and "exitMessage = Failed to acquire lock: No space left on device"

the hosted-engine --vm-status :
Engine status : unknown stale-data
stopped : False

I didn't find succeed to access it using SPICE/VNC.

I'm running a self-hosted-engine on a single host.

Any idea how I can disable the VLAN tagging for this VM using vdsClient ?

I really need help with this !
