Xen users - May 2009 - 64 bit domU

May be my question is a stupid. But I can''t get working 64 bit guest
OS.

I''m using debian 5.0.1 with xen-3.4.0 (it was compiled manually
today to get FreeBSD guest OS working)

I have tried to use following configuration for my guest os:

kernel = "/usr/lib64/xen/boot/hvmloader"
builder=''hvm''
memory = 1024
name = "freebsd"
vcpus=1
pae=0
acpi=1
apic=1
arch=''test''
vif = [ ''bridge=eth0'' ]
disk = [
''file:/xen/image/freebsd.img,hda,w'',
''file:/xen/iso/7.2-RELEASE-amd64-bootonly.iso,hdb:cdrom,r'' ]
on_poweroff = ''destroy''
on_reboot   = ''restart''
on_crash    = ''restart''
device_model = ''/usr/lib64/xen/bin/qemu-dm''
boot=''cd''
sdl=0
vnc=1
vncviewer=1
vncdisplay=3
vncunused=0
vncpasswd=''12345''

In VNC console I see:
CPU doesn''t support long mode

I have got same result with debian x86_64 as guest os.

Does your CPU have long mode support [1]?

With the same CPU i think.

Yes, It has. It''s dual Xeon server. It was bought specially for xen
with hvm usage (with VT support). In my previous post you can see
there is dom0 booted with x86_64 kernel.

Question is closed.
Solution: pae=2 in config.
Two days of internet searching and manuals smoking  :)
