Fluent virt-install Windows XP HVM DomU at Solaris (SNV_92) Dom0

Due to known bug virt-install is not approved method for mentioned installation. However, simple bash script (monitor) provides an option to attach cdrom via xm block-attach command immediately when it will be lost by virt-install after first DomU reboot.
Start virt-install for Windows HVM DomU in first terminal session:-

virt-install -n WinXP --hvm -r 1024 --vnc \
-f /export/home/images/winxp.img -s 5 \
-c /export/home/isos/winxp.iso
  

At the same time start running following script in second terminal session:-

#!/bin/bash 
COUNTER=1
while [  $COUNTER -eq 1 ]; do
 COUNTER=`xm list -l WinXP|grep cdrom|wc -l`
 sleep 1
done
xm block-attach WinXP file:/export/home/isos/winxp.iso hdc:cdrom r
xm reboot WinXP
 

When scripts exists wait for several seconds.
and issue from same terminal:-

vncviewer localhost:0
  

to proceed with install as normal.
Message in first terminal session.
