Playing around with xen 4.0.1, trying to setup a simple domU.
When I put the parameter in vif like :
vif = [ 'ip=192.168.1.41,mac=00:16:3E:2F:F4:78,bridge=xenbr0,vifname=domu1' ]
It fails
error: Device 0 (vif) could not be connected.
ip link set vif5.0 name domu1 failed
Also, running the command from dom0:
ip link set vif5.0 name domu1
returns
RTNETLINK answers: Device or resource busy
Any idea ?

From what I can tell the
vifname=
command isn't properly supported in many versions of Xen.My guess is that you can only rename the device before certain usage and the Xen vif scripts are doing it too late.
Looking at the source in
vif-common.sh
:I don't see any obvious bugs. You should look at your
vif-common.sh
and confirm that it is the same as this.Edit: I think maybe the vifX.Y interface may not be up at this point. Try commenting out the
do_or_die
line. That should setvif="$vifname"
and if the device is then created later there is no reason to rename it.
