[CentOS-virt] no virtual network until vnc connection

[gisto85]

Hi,

I have a host with 3 guests  ( 2 CentOs 1 Windows 2003 )
If I shutdown or reboot host the virtual machines starts up with no problems,
If I pull down power supply when power come back host regulary
startup, the vm startup ( autostart ) but vm machines network doesn't
works
until I connect  to vm console ( e.g.: vncviewer 192.168.2.X:2 )

The host is "hp proliant ml350 g5" with network bonding  (fault
tolerance) CentOs 5.6, I have another identical server
with 2 centos machines and no problem in case of power fault, when
power come back the vm network start regulary.
I attach some configuration files.

Thanks in advance
Egidio
