RE: [Xen-users] Error "Device 0 (vif) could not be connected"

[wei huang <huanwei@xxxxxxxxxxxxxxxxxx>]

Hi

Thank you for your suggestion.

I do have a vif line in my config:
vif = [ 'mac=aa:00:00:00:01:05, bridge=xenbr0' ]

But unfortunately, I tried either change it to vif0 or remote it. I get
the same error:
#c4xen# /etc/xen> sudo xm create -c as4_conf
Using config file "as4_conf".
Error: Error creating domain: Device 0 (vif) could not be connected.
Backend device not found!

Do you see the same problem and you fix that in this way?

Thank you again!

Regards,
Wei Huang
