[pve-devel] qemu-server : don't unplug nic on update

[Alexandre DERUMIER]

Do you have my today patch ?  ("don't unplug nic on update")

It should fix it.

The problem was that on update, I tried to unplug then plug network card.
As your guest don't have hotplug acpi modules, the unplug fail.

Hi, 

yes current git code isn't usable for me anymore. 

The dmesg output looks like this and then the network is and stays offline.
