Hi,
When I install Oracle RAC on Xen VM, some problem occurred. How can
I configure two NICs on a Xen's DomU. You know, RAC's installation requires
two NICs on a node. I am a newbie about Xen. Please give me some advice.
Thanks.

Thanx a lot Jorge.
That solved the problem. I have it up and running now.

Hi, Noniko.
I fitted same thing. When I was verifying Xen on SLES10 Beta.
> /var/lib/xen/images/vm1/hda. Wonderful.
It is whole disk image.

This error is correct. Because hda is not filesystem.
Please try following step.
1. Mapping hda to /dev/loop0.
# losetup /dev/loop0 /var/lib/xen/images/vm1/hda
2. Look at geometric information on /dev/loop0.
# fdisk -l -u /dev/loop0
Disk /dev/hda: 30.7 GB, 30738677760 bytes
255 heads, 63 sectors/track, 3737 cylinders, total 60036480 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/loop0p1 63 208844 104391 83 Linux
/dev/loop0p2 208845 60034904 29913030 83 Linux
3. Calculate the offset. offset = Start x Unit size
# offset=((63*512))
4. Mapping hda1 in /dev/loop0
# losetup -o $offset /dev/loop1 /dev/loop1
5. Mount /dev/loop1 to /mnt/vm1_hda1
# mkdir /mnt/vm1_hda1
# mount /dev/loop1 /mnt/vm1_hda1
That's all.

After several problems with sata and kernel compiles, and ofcourse help from
the list to solve it, i got the kernel compiled and xen-unstable running on
Celeron D 64bit.
Now xen has been setup for route network. However when i try to ping domU
from dom0 it gives no responses, vice versa, ping from dom0 to domU doesn't
work.
The dom0 is a centos 4.3 and domU is centos 4.3 again.
I have tried many things, however network still doesn't work.
>From domU to dom0 ping gives the following error:
connect: Network is unreachable
Ping from dom0 to domU gives no response.
Any help will be appreciated.

route -n looks fine on dom0. The ip address of the domU shows up in route
and proper interface is showing up for the same as well.
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.75.61.2 0.0.0.0 255.255.255.255 UH 0 0 0

0.0.0.0 192.75.44.1 0.0.0.0 UG 0 0 0 eth0
Here 192.75.61.2 is the domU, 192.75.44.1 is the gateway for dom0 and
192.75.44.9 is the ip for dom0.

I had this same problem on the DomU to other machines. Executing dhclient
got an address. You might try that, although it is, of course, an
unsatisfactory long-term solution.
I posted a similar question a few days ago and got a pointer to:
http://wiki.xensource.com/xenwiki/XenNetworking
with a suggest to execute:
echo 0 > /proc/sys/net/ipv4/ip_forward
I did that, but did not find it helped; however, it might work for you.
