Re: [Xen-users] Xen Starting DomainU:Error: Device 0 (vif) could not be connected. Hotplug scripts not working

[Sanjay Upadhyay <glowfriend@xxxxxxxxx>]

check,
ifconfig
and see xenbr0 is running.. and you have a line in your domU conf file like this
vif1 = [ 'bridge=xenbr0' ]

you can directly start the network script by running
#>/etc/xen/scripts/network-bridge start

regards
