Btw:  I think that the extremely bad fork_* performance
can only observed when running the 32-bit PAE
hypervisor, and when the system uses less than
4GB of memory. I filed bug 6702228 for this problem.

Second option for profiles:-
***********
Installation 
***********
root@boris-desktop:/etc/xen/vm# cat solaio.hvm
name="Solaris89HVM"
builder=''hvm''
memory=1024
disk=[''tap:aio:/etc/xen/images/snv.img,hda,w'',''phy:/dev/loop0,hdc:cdrom,r'']
vif=[''type=ioemu,bridge=eth0'']
device_model = ''/usr/lib64/xen/bin/qemu-dm''
kernel=''/usr/lib64/xen/boot/hvmloader''
vcpus=1
serial="pty"
sdl=1
boot="d"
on_reboot   = ''restart''
on_crash    = ''restart''
*********
Runtime
*********
root@boris-desktop:/etc/xen/vm# cat sol89aio.hvm
name="Solaris89HVM"
builder=''hvm''
memory=1024
disk=[''tap:aio:/etc/xen/images/snv.img,hda,w'']
vif=[''type=ioemu,bridge=eth0'']
device_model = ''/usr/lib64/xen/bin/qemu-dm''
kernel=''/usr/lib64/xen/boot/hvmloader''
vcpus=1
serial="pty"
sdl=1
boot="c"
on_reboot   = ''restart''
on_crash    = ''restart''
Both options:-
disk=[''tap:aio:/etc/xen/images/snv.img,hda,w'',''phy:/dev/loop0,hdc:cdrom,r'']
disk=[''phy:/dev/sdb13,ioemu:hda,w'',''phy:/dev/loop0,hdc:cdrom,r'']
work fine.
I didn''t have to losetup writeable device as suggested in blog
