Yep, just checked my RHEL-5 box and it has this config
name = "f11i686xen"
uuid = "1417ac4b-bd9a-61cc-6faf-8e842cd72cb9"
maxmem = 900
memory = 500
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1" ]
disk = [ "tap:aio:/var/lib/xen/images/f11i686.img,xvda,w" ]
vif = [ "mac=00:16:3e:71:38:63,bridge=xenbr0" ]
Nothing weird here.. My guest has 1 vcpu aswell, and I'm using vnc.
And the guest disk is fully instlaled
# ls -lhs /var/lib/xen/images/f11i686.img
3.4G -rwxr-xr-x 1 root root 5.1G Jun 4 06:33 /var/lib/xen/images/f11i686.img
FWIW, the guest kernel here is 2.6.29-0.258.rc8.git2.fc11.i686.PAE
So its possible things have changed since I did my install ....
Default kernel in Fedora 11 is: kernel-PAE-22.214.171.124-167.fc11.i686.rpm
Also my x86_64 host only has 2 GB of RAM, so if there's any bugs
i686 guests at the >4GB phys RAM mark I wouldn't have seen them
My guests were using 512 MB and 1024 MB of RAM..
I tried again now, and yes, F10 and F11 i386 guests fail on CentOS 5.3
x86_64 dom0 with domU kernel crashes like this:
Checking if this processor honours the WP bit even in supervisor mode...Ok.

Hmm.. I wonder what's causing this.
Can you test if it works for you?
I used virt-install like this:
virt-install --debug -n testvm -r 512 --vcpus=1 -f /dev/VolGroup00/testvm_disk --vnc -p -l
The graphical VNC console newer shows up, and when I run "xm console testvm"
I see that kernel crash.
