Comment 2 Daniel Berrangé 2007-03-21 02:18:53 UTC 
Does xenbr2  exist as a bridge device, and if so, did you see any SELinux AVC
errors reported perhaps ? The latest Xen ought to give a sane error message if
the former occurred, so I can only suspect the latter based on the logs.
Comment 3 ericm24x7 2007-03-21 17:05:55 UTC 
Yes xenbr2 does exist as bridge device. I didn't see any AVC error, but to put
selinux out of the equation I disabled it by executing "setenforce 0". Same problem.

My guess of the problem: 
virt-install is trying to configure and install from the first network (eth1,
which it found first) rather than from the preferred second network (eth2, where
the install source is located). Maybe xen couldn't properly configure all the
virtual interfaces required for multiple LAN cards. I have 3 LAN cards currently
installed. 

When I get a chance I'll try having only one LAN card and see if it works.

Comment 6 ericm24x7 2007-03-23 20:57:28 UTC 
With the latest devel build, everything works with the exception of selinux
blocking the virt-manager from proceeding. 

I will close this one and open another for selinux problem.
