I am using Srv2008 X86. The memory size in this VM shows as 5.97GB. And 
I thought PAE mode was
enabled in this OS if the memory size is larger than 4G and pae was set 
1 in vm configure file. right?

Following is my Srv2008 X86 configure file:

acpi = 1
apic = 1
boot = 'c'
builder = 'hvm'
bootloader = '/usr/bin/pygrub'
device_model = '/usr/lib/xen/bin/qemu-dm'
disk = [
'file:/mnt/running_pool/win2k8/System.img,hda,w',
]
kernel = '/usr/lib/xen/boot/hvmloader'
memory = '6114'
name = 'win2k8_32'
on_crash = ''
on_reboot = ''
pae = 1
#serial = 'pty'
timer_mode = 1
usbdevice = 'tablet'
vcpus = 1
vif = [
'mac=00:16:3E:5E:DF:29, bridge=xenbr0',
]
vnc = 1
vnclisten = '0.0.0.0'
vncunused = 1

Thanks
