Hello,
I''m having a problem with network connection on created domains.
I''m running
Xen 3.2 on Ubuntu 8.04, server has 2 NICs but I use only one. I had no
problems installing and running Xen, domU has normal network connection, but
none of other domains.
My current test domain is set for dhcp, but it doesn''t pick up any
signal.
Same situation was with fixed network settings, domain behaved as though it
was "unplugged". Checked all settings on guest system, they seem to be
more
than fine. On host system, I am anxious about double eth0 in network-bridge
status (see below), but I have no idea where it came from and how to get rid
of it. I also failed to find anyone with similar problem.
Cheers,
Kamila Gador
