[Xen-devel] Re: stubdom (with vif) startup failure

[Dulloor <dulloor@xxxxxxxxx>]

Problem is irrespective of vif-bridge or vif-nat. With vif-bridge, I get the following in qemu-dm.log :

***
xm create -c /data/xen-devel/xen-guest-confs/linux.hvm-dm target=13 memory=32 videoram=4 extra=" -d 13"
Using config file "/data/xen-devel/xen-guest-confs/linux.hvm-dm".
Started domain linux.hvm-dm (id=14)
Unexpected error: <type 'exceptions.OSError'>

Hey,

I have a problem getting a linux HVM (stubdom) working, when I have a network(vif)  configuration. I am at xen-unstable tip and using kubuntu hardy.

***
I mean -
vif = [ 'ip=10.0.0.5', 'type=ioemu, ip=10.0.0.1' ] is a problem, and
vif = [ '', 'type=ioemu, ip=10.0.0.1' ] is not.

The qemu-log shows the following error (added an extra print info) -
xm create -c /data/xen-devel/xen-guest-confs/linux.hvm-dm target=8 memory=32 videoram=4 extra=" -d 8"
Using config file "/data/xen-devel/xen-guest-confs/linux.hvm-dm".
Error: Device 1 (vif) could not be connected. ip route add 10.0.0.1 dev vif9.1 src 10.0.0.128 failed
