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

[Coral Lin <lin.coral@xxxxxxxxx>]

hi,

 

I am trying to start a new domainU but got the error:

Error: Device 0 (vif) could not be connected. Hotplug scripts not working

I have struggled with it for a long time. I found somebody else report this but can not find a solution.

The xen version is xen-3.0 latest version.

I do not have a initrd.

Domain0 works fine but when I create a new domain, it always gives an error as above. 

 

Thanks,

Coral

Here is the logs:
