Re: [Xen-users] xm create: Error: Device 0 (vif) could not be c

Hi Geoff,

Thanks for prompt reply.� I have assigned correct interface. Please see below for more detail,

[root@localhost rules.d]# brctl show

bridge name�� bridge id�� STP enabled�� interfaces

eth0�� 8000.001c2596e32b�� no�� peth0

pan0�� 8000.000000000000�� no

virbr0�� 8000.000000000000�� yes

[root@localhost xen]# cat test|grep -i vif
vif = [ 'type=ioemu, bridge=eth0' ]

root@localhost xen]# xm create test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

Looking the xend.log, I can see that, vif� virtual interface device is created and� for status it is waiting in dom0(backend side) for hotplug callback status of device... for more details see below full xend.log,� I have highlighted vif log details in red color just for better visibility... Please guide me through my installation.

Check your vif=statement (domU config) and or bridging. "brctl show" and any xend logs helps the situation.
