Hi folks,

I’m using FC6 (kernel 2.6.19-1.2895.fc6xen), with SELinux disabled. I’m running on a Dell D820 laptop with vmx extensions enabled (confirmed by looking for vmx in /proc/cpuinfo), trying to boot a RH7.2 (uh, yeah, don’t ask…) fully-virtualized guest.

I used virt-manager to successfully install RH7.2 on a disk image. However when I then try to boot from the image, on the console I see:

MXT page nr start=ffffffff len=ffffffff

Ooops! Too many entries in the memory map”

Spewed out a lot of times, followed by some kernel information, ending up with:

“Unable to handle kernel paging request at virtual address ffffffff”

This ends in a kernel panic, complaining:

“<0> Kernel panic: Attempted to kill the idle task! In idle task – not syncing”

Here’s my config file:

# Automatically generated xen config file

name = "rh72a"

builder = "hvm"

memory = "500"

disk = [ 'file:/home/user/rh72.xen.img,hda,w', ]

vif = [ 'type=ioemu, mac=00:16:3e:57:24:2a, bridge=xenbr0', ]

uuid = "c77c61e4-3294-2bc2-7005-92b92d3191d2"

device_model = "/usr/lib/xen/bin/qemu-dm"

kernel = "/usr/lib/xen/boot/hvmloader"

vnc=1

vncunused=1

apic=1

acpi=1

pae=1

vcpus=1

serial = "pty" # enable serial console

on_reboot   = 'restart'

on_crash    = 'restart'

Am I missing something obvious? Any more info I can provide that would be helpful?

Thanks for any help you might offer.
