Subject: [9fans] Plan 9 on Xen 3.2.1 / 32-bit PAE Kernel / 64-bit Hypervisor

Wow, thanks for the fast responses!

For what it's worth, the following is my Xen config:
kernel = "/home/kvanals/plan9/9xeninst-pae.gz"
memory = 32
vcpus = '1'
name = "plan9.kvanals.org"
vif = [ 'mac=00:16:3E:9F:FF:01' ]
disk = [ 'file:/home/kvanals/plan9/plan9.img,sda,w',
         'file:/home/kvanals/plan9/plan9.iso,sdb,r' ]
reboot = 'never'
extra="""
nobootprompt=local!/boot/bzroot
bootfile=sd01!cdboot!bootdisk.img
"""


Furthermore, this box only has 4GB of physical memory:
wired:~# xm info | grep total_memory
total_memory           : 4095

Mr. Miller:  I attempted to use your newly uploaded kernel, but was
greeted with a very similar panic:
wired:~# xm create -c /home/kvanals/plan9/boot.conf
Using config file "/home/kvanals/plan9/boot.conf".

Upon doing some "Googling" I came across one other mention of this problem
on 9fans, but it was never solved:
