[pve-devel] random vm start fail but tap device not cleaned.

[Alexandre DERUMIER]

Hi Dietmar, I have had this problem twice. 
vm start hang, then I stop the vm but the tap device is not cleaned, then I can restart it

Do you know how I can remove the tap interface manually ?



#qm start 10385
--> hang

#qm stop 10385
VM quit/powerdown failed - terminating now with SIGTERM

VM still running - terminating now with SIGKILL

#qm start 10385
