[PVE-User] proxmox-ve: 5.4-2 can't access webinterface after update

[kai at zimmer.net]

Hi, 

i updated my Proxmox VE Host (via 'apt-get update; apt-get upgrade').
Now the web interface is not accessible anymore. Additionally i have
disconnected network devices in the webinterface before the update. I
can start the VMs via 'qm start 100', but they cannot get network (and i
don't know how to fix this on the command line). 

To fix the web interface i tried 'service pveproxy restart' and 'service
pvedaemon restart' - with no success. 

To fix the network in the VMs i tried 'qm set 100 --net0
model=virtio,link_down=1' and 'qm set 100 --net0
model=virtio,link_down=0' - also without success.
