I am on SLES9 based system running Xen-unstable. I created a DomU based
off of my SLES9 base system. I made the appropriate changes to the
network configuration but I am unable to get eth0 working. I have tried
both DHCP and static IPs. I have listed the output of "ifconfig -a"
and
"cat /proc/interrupts" on Dom0 below. I have left out eth1,2,3 because
they are not wired.
When I try to bring up the eth0 interface using DHCP on DomU I get a
message saying "Unable to obtain IP address...backgrounding". When I
try
to do a static config, the interface comes up but I am not able to ping
out.
The network connectivity in Dom0 works fine. Could you please tell me
what I am doing wrong?
Thanks

Re: [Xen-users] Network on DomU not working
Fernando,
Yes I have DHCP running on my network. Dom0 gets its IPs using DHCP. The
DHCP server is not configure to in the way you described. We have VMware
running in the same lab without any problems.
Here is my ifconfig output with DHCP

Dear Aravindh
1) Do you have a DHCP server running in your network?
2) Sometimes, DHCP servers do not serve an ip address
range, instead they just respond if the mac address
is in its list of fixed addresses. May be your DHCP
server (if there is one) is configured that way...
3) From inside domU, if you issue a "ifconfig eth0",
what comes up?

Just install tcpdump into the Xen hostess machine, issue a command like: # tcpdump -i xen-br0 -n port 67 And boot your domU. It will try to get an ip addr from the net, you should be able to see traffic flowin.. check for the mac address (HWaddr) above. Also verify if the mac above is not duplicated.. -- Bye, Fernando Maciel Souto Maior fernando@araujo.com.br http://www.araujo.com.br +55+31 3270-5886 LPIC/1 # 31908 AVISO------------------------------------------------------------- Esta mensagem pode conter informacao confidencial ou privilegiada.
