Almost all my Guest VMs (Windows XP) lose network connections occasionally. The only one way to recover it is to stop and start VM again.

If I look at the VM via Web ProxmoxVE it displays:
Code:
Network Divece displays: e1000=X.X.X.X.X.X,bridge=vmbr0,link_down=1

If I click on the network device and try to change anything it shows:
Code:
Parameter verification failed. (400)

net0: hotplug problem - VM 117 qmp command 'netdev_add' failed - Duplicate ID 'net0' for netdev

Proxmox is from the Enterprise repository on the server.

Code:
 # pveversion -v
proxmox-ve: 4.2-64 (running kernel: 4.4.16-1-pve)
pve-manager: 4.2-18 (running version: 4.2-18/158720b9)

Any chance to solve this problem or at least setup network connection without sopping/starting VM?

Thanks.
