[Xen-users] Need help with networking in DomU''s

Fedora Core 4 Dom0 and CenOS 4.1 DomU as outlined similarly at Mark
Foster''s wiki which doesn''t seem to be up at the moment.

uname -a on Dom0
Linux w2knt412 2.6.12.6-xen3_2.1_fc4 #1 SMP Sun Dec 4 11:19:39 PST 2005 i686
i686 i386 GNU/Linux

Dom0 comes up and is on the network and I can VNC into Dom0 from other computers
on the network just fine. However, my DomU''s startup and seem to be
useable from the DomU console but I can''t get their networking to go
out to the world. What changes do I need to make to which config files to get my
DomU''s to go out to the network and to the Internet? Thanks.

Re: [Xen-users] Need help with networking in DomU''s

Additional info:
ifconfig inside the DomU comes up looking like this below initially after DomU
startup:

eth0      Link encap:Ethernet  HWaddr 00:16:3E:6E:57:3E
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

If I give it an ifconfig eth0 10.1.1.215 netmask 255.255.255.0 followed by an
ifconfig eth0 up it''ll take the information and a new ifconfig
afterward will show the new IP and netmask but it still doesn''t get me
out through the bridge and to the network and the Internet.

Any help appreciated.

Re: [Xen-users] Need help with networking in DomU''s

How did you install Xen?

If you used the install script for FC4 off the xensource website, then you
may want to think about grabbing the source and compiling it yourself.  I
tried this first and after a lot of stability problems and network issues
with my domU domains I gave up and compiled Xen myself.

I''m now running Xen3 compiled from the testing source code and
everything is
working very well right out of the box.

Re: [Xen-users] Need help with networking in DomU''s

Thanks Eric. You were right -- there seemed to be a problem with the FC4 install
scripts I was using. However, I was able to get it all to work with CentOS 4.2,
the Xensource tarball and enough reading to comfort me through three arctic
winters.
