[Xen-users] Only one pv domU works with tap:aio

[Johnny Bravo <JohnnyBravo@xxxxxxx>]

Hello! have a problem using 2 PV domu with tap:aio disk image file

I install Suse 11.1 x 64 as PV Domu on Suse x64 Dom0
the running config for DomU is

bootloader = '/usr/bin/pygrub'
builder="linux".
extra
=
'xencons
=tty'.............................................................

on_poweroff
='destroy'...........................................................
on_reboot
='restart'.............................................................
on_crash
='restart'..............................................................
on_xend_start='start'
on_xend_stop='shutdown'.
...........................................................

name = "Suse1"
#uuid = ''
memory=512
vcpus = 1
vif = ['bridge=br0,vifname=susedl0']
disk = ['tap:aio:/etc/xen/images/suse1.img,xvda,w']

everything works great,
than i clone config and image files for second PV DomU. its config is:

bootloader = '/usr/bin/pygrub'
builder="linux".
extra
=
'xencons
=tty'.............................................................

on_poweroff
='destroy'...........................................................
on_reboot
='restart'.............................................................
on_crash
='restart'..............................................................
on_xend_start='start'
on_xend_stop='shutdown'.
...........................................................
name = "Suse2"
#uuid = ''
memory=512
vcpus = 1
vif = ['bridge=br0,vifname=suse20']
disk = ['tap:aio:/etc/xen/images/susedl.img,xvda,w']


and it also works great but when first domu is stoped
if i try run both domu in same time one of them doesnot boot, xm  
conslole give me this
XENBUS: Waiting for devices to initialise: 295s...290s...285s... etc

and when I try to reset or shutdown Suse2 Dom0 hold for 1 min and than  
I cant create any PV domains
if i change tap:aio in config files to file: both PV works in same time

Where is my mistake?
