[Xen-users] domU keep crashing when install ubuntu as pv domU

["AR (aka AleiPhoenix)" <aleiphoenix@xxxxxxxxx>]

I'm using xen 4.3 with gentoo as dom0.

the kernel and ramdisk file is taken from http://ftp.jaist.ac.jp/pub/Linux/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/

the pv domU config file (according to the ubuntu xen documentation https://help.ubuntu.com/community/Xen)

precise.cfg

name  = "precise"
kernel = "/xen/kernels/precise/vmlinuz"
ramdisk = "/xen/kernels/precise/initrd.gz"
# builder = "linux"
# bootloader = "pygrub"
memory Â= 512
extra  = "debian-installer/exit/always_halt=true -- console=hvc0"
# device_model_override = "/usr/lib64/xen/bin/qemu-dm"
vif   = ['bridge=br0',]
# disk  Â= ['file:/xen/livecd/ubuntu-12.04-server-amd64.iso,xvdc:cdrom,r', 'phy:/dev/vg/precise_root,xvda,w', 'phy:/dev/vg/precise_swap,xvdb,w']
disk  Â= ['phy:/dev/vg/precise_root,xvda,w', 'phy:/dev/vg/precise_swap,xvdb,w']
# root  Â= "/dev/xvdc"
vfb   = ['type=vnc,vnclisten=0.0.0.0,vncunused=1']
vcpus  = 2
boot  Â= "d"

vnclisten = "0.0.0.0"

#
# on_crash Â= 'restart'



When i type "xl create precise.cfg", the domU started and simply get crashed.

and try to boot domU as hvm


builder = "hvm"


the iso booted very well, but report i686 cpu detected.

I'm running on an Intel Core 2 E7500 CPU , and VT-x is turned on.

I'm confused.

Someone could help me out, thanks!
