I had a supermicro server SuperServer 1027R-WRF4+ and a old Dell PowerEdge 2950.

In both machines I setup centos 6.5, which is running

I follow Xen4Cen wiki to setup Xen, I had other servers running Centos
5.x without issues.

Now, once I build my vm's dom-u centos 6.5/centos 5.9 both x64, I
receive different erros, let me show u the message I receive in my
console for centos 6.5 dum-u.

xl  console oerp-server
PCI: Fatal: No config space access function found
ipmi_si: Could not set up I/O space
ipmi_si: Could not set up I/O space
ipmi_si: Could not set up I/O space

Something related to ipmi in my server which is enable by default? can
be, now what happen is I try to boot xentos 5.9 x64 dom-u:

Looks is not finding the dom-u disk.

In both cases I'm using almost the same settings:

name = "centos5"
uuid = "5020979f-8dae-105d-df56-9fb28d377aa2"
bootloader = "/usr/bin/pygrub"
memory = 2048
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
disk = [ "tap:aio:/ext4/centos5/disk.img,xvda,w" ]
vif = [ "mac=X:X:X:X:X:X,bridge=xenbr0,script=vif-bridge" ]

The main line of centos stock without Xen continue using kernel 2.6.x,
but Xen is using the new line 3.x.

Anyone else with this issue?

Thanks for your time.
