Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed
 
try booting with pci=nomsi on the kernel line,
 If you setup networking according to this then things should be working, 
and no need to
use vif in the bridge line:

One of my working confs looks like this (CentOS 5.6 Xen 4.1):
name = "test1"
memory = "512"
disk = [ "phy:/dev/vg1/test1,xvda,w" ]
vif = [ 'mac=00:16:3e:aa:aa:91,bridge=xenbr0' ]
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
bootloader = "/usr/bin/pygrub"
on node:
# netstat -rn

Todd,
 
What is the output of running the command: xl create -c trillian
 
 
I don't know. I had to switch to another box; one that is not running my mail 
server in a
VM :) Why did I think this was going to be easy...
The other box, also running CentOS 5.6, will not boot with xen 4.1. The stock 
xen worked fine.
Running with the DEBUG=Y on xen and kernel command line, I see its not able to 
recognise
the disk drives and build the raid device.
I get errors like:
ata2: Sata link up 3.0 Gbps (SStatus 123 SControl 300)
ata 200: failed to identify (io error, err_mask=0x4)
ata2: failed to recover some devices retrying in 5 secs
Booting with non-xen kernel works fine. My brain is numb from hours of googling 
to no
avail. I'll try again tomorrow.
Regards,
        Andy
