Hi,
referreing the docs on
http://www.howtoforge.com/perfect_xen_setup_debian_ubuntu_p6 I had set
up my networking in Xen 2.0.7, and which used to work. However After
updating the Xen to 3.0.0, the same configuration doesnt work any
more..
SU-debian:~# xm create -c debian-1
Using config file "debian-1".
Error: Device 0 (vif) could not be connected. Backend device not found.
When viewed under 'xm list' I can see that the domU is paused. I can
unpause it and run, however network never comes up. I cannot ping the
dummy0 IP from the DomU console.
SU-debian:~# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 376 1 r----- 6523.0
Tarooza 3 216 1 ------ 452.8
suxen-1Deb 4 64 1 --p--- 0.0
Booting the Domu generates the following error (xend.log)
