You need to use # to mask this line:
(while true ; do sleep 60 ; done) | /bin/sh -c "$creation" & ,
Also you can redirect log messages to a file, just modify this line:
creation=”xm create –c $domname-dm target=$domid memory=32 extra=\”$extra\""
To
creation=”xm create –c $domname-dm target=$domid memory=32 extra=\”$extra\"
>/your_log_file"

Subject: Re: [Xen-users] Problem with start winxp on xen-3.3.0 using stubdom
I have uncomment line 'xterm -geometry ......' in /usr/lib/xen/bin/stub-dm,
and two windows popped up, the first one closed automatically, and the second
window said:
Using config file "/etc/xen/winxp-dm"
Error: Domain 'winxp-dm' already exists with ID '17'
Press ENTER to shut down
$ cat ps aux | grep stub

Is it normal to start two stubdoms for one domain? how to avoid it?
2008/10/30 Niu Yan <vivian.niu@xxxxxxxxx>
I have try with disk = [ 'file:/home/images/winxp.img,hda,w' ] and set
boot='c' , the result is the same.
2008/10/30 Wan, Shuang <shuang.wan@xxxxxxxxx>
Hi NiuYan,
disk = [ 'phy:/dev/cdrom1,hdc:cdrom,r', 'file:/home/images/winxp.img,hda,w' ]
Enable the hdc:cdrom configuration option in disk section is a known issue to
stubdom(tested changeset 18569), you can try to remove it.
And also there a another place you can catch many of useful log message, you
can edit the /usr/lib/xen/bin/stubdom-dm, change the lines as bellow:
#(while true ; do sleep 60 ; done) | /bin/sh -c "$creation" &
xterm -geometry +0+0 -e /bin/sh -c "$creation ; echo ; echo press ENTER to shut
down ; read" &
it will popup a xterm window, you can see many of messages from that.
Best regards
Wan Shuang

Subject: [Xen-users] Problem with start winxp on xen-3.3.0 using stubdom
There is some messages talking about start windows using stubdom on
xen-devel@xxxxxxxxxxxxxxxxxxx, but i think it may be more proper to send it
here.
---------------------------
I have start winxp on xen-3.2.0 normally, but I want to use stubdom , so I try
it with xen-3.3.0, I followed the steps in stubdom/README, including:
$ mkdir -p /exports/usr/share/xen/qemu
$ ln -s /usr/share/xen/qemu/keymaps /exports/usr/share/xen/qemu
$ mkdir -p /exports/var/lib
$ ln -s /var/lib/xen /exports/var/lib
$ /usr/sbin/fs-backend &
$ xm create winxp
except name the configuration file with 'winxp' and 'winxp-dm'. They are as
follows:
$ cat /etc/xen/winxp
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 1280
name = "winxp"
vif = [ 'type=ioemu, bridge=xenbr0' ]
device_model = '/usr/lib/xen/bin/stubdom-dm'
boot="dc"
sdl=0
opengl=0
vnc=0
vncpasswd=''
stdvga=0
$ cat /etc/xen/winxp-dm
kernel = "/usr/lib/xen/boot/ioemu-stubdom.gz"
vif = [ '', 'type=ioemu, bridge=xenbr0' ]
disk = [ 'phy:/dev/cdrom1,hdc:cdrom,r', 'file:/home/images/winxp.img,hda,w' ]
But the sdl window closed quickly after two blink.
