[Xen-users] Xen3.0, CentOS4.2, client spikes CPU and restarts

[Eric <eb-xen@xxxxxxxx>]

I installed from the binaries at

http://www.karan.org/mock/Xen/i386/


and followed the install portion of the script provided by Aaron.  
All seemed to go well.  I then copied xmexample2 to my_xmconfig and made the following adjustments:

kernel = "/boot/vmlinuz-2.6-xen"
memory = 128
vcpus = 1
nics=1
disk = [ 'phy:mapper/VolGroup00-LogVol0%d,sda1,w' % (3+vmid) ]
extra = "4 VMID=%d " % vmid

needless to say, I'm trying to run the client from a LogicalVolume :)

I made a snapshot of my running system (after installing xen) and copied 
it over to another volume (so I would have the same starting place).  I 
fixed /etc/fstab, /etc/hosts and the 
/etc/sysconfig/network-scripts/*eth0 (replacing the IP with the next 
available on this test network)
when I run:
xm create -c my_xmconfig vmid=1

All seems to go well, up to the point that the system reports:

NET: Registered protocol family 8
NET: Registered protocol family 20
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 184k freed
Warning: unable to open an initial console.
unix: no version for "struct_module" found: kernel tainted.
NET: Registered protocol family 1
Restarting system.

It looks like the client spikes its CPU to 100% and restarts after about 
25 seconds.  It feels like it is hanging while probing for devices..
I've checked the logs- xend-debug.log stays empty.   The vif# continues 
to increase in xend-hotplug.log, but that seems to follow from the fact 
that the client keeps restarting.  By the time this last attempt gave 
up, xend.log was reporting dom=173.
I haven't tried disabling the network yet, but it is next on my list...

Any suggestions for what I may have done wrong?  What additional info 
would help?

Thanks,
Eric
