Hi all,


I have a CentOS 5.5 box running Xen 3.0.3 under which I run several Windows 2003 Enterprise solutions.
Now, after doing a software upgrade last Friday, I restarted the CentOS box.
After the restart, one of my Windows installations refuses to run.

I see a brief startup-screen finding disk(s) and then I get a black screen with this message:

"Attempting to load x64 Operating system, however, this system does not have the APIC configured."

Now, I have apic configured, and the image contains a 32 bit version of 2003 server, not 64 bits. All other images I have run just fine.
The troubled image ran fine also, prior to update/reboot.

Is there any reason why I'm getting this message? Is there anything I can do?


Hope somebody can help me with thius.


Cheers,


-Morten


Here is the config for the hvm:

name = "VarnerTest"

maxmem = 1032
memory = 1032
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
localtime = 1



device_model = "/usr/lib64/xen/bin/qemu-dm"
usbdevice = "tablet"
sdl = 0
vnc = 1
vncunused = 1
keymap = "no"
disk = [ "file:/var/lib/xen/images/VarnerTest.img,hda,w", ",hdc:cdrom,r" ]
vif = [ "mac=00:16:3e:46:ed:52,bridge=xenbr1" ]
serial = "pty"


And here is dmesg:
