Xen users - Jul 2011 - xendomains and xl toolstack question

Hello all

I''ve just installed xen 4.1.1 on my server and was tryoing to tweak
xendomains script to work with new xl schema but I can´t get it to save
domains. It does start them with some changes I made to it but when I issue
service xendomains stop I just get [  OK  ]  but domains stay running.

Has xendomains script been ported to work with 4.1.1 or is there another
alternative to it.

Thank you very much.

Hello all

It does start them with some changes I made to it but when I issue service

I see you want to use xl and xendomains together. I believe that xendomains
service still needs xend service running.

If you check your
/etc/rc2.d
/etc/rc6.d

xencommons, xend, xendomains needs to start in this order in rc2 and shutdown
opposite in rc6.

When you have multiple guests running it can be risky to shutdown when you
aren''t sure that guest will shutdown too.
For this reason I use the script below to shutdown guests that show in `xm
list`. If you use xl, you might need to modify down_xm.sh

--------------------------- script ------------
>cat >>down_xm.sh<<EOL
#!/bin/bash
#
# script to take down Xen guests before xendomains goes down
# Last created guests shutdown first (LIFO)
# author: ChmEarl on ##xen on Freenode
#

PATH=$PATH:/sbin:/usr/sbin

TP=$(xm list| gawk  ''{if ( FNR>2) print $2 }''|sort -rn)

TP=$(echo $TP|sed "s/\n/ /g")
# sortspaces() { tr '' '' ''\n'' <<<
"$@" | sort | tr ''\n'' '' ''; }
echo "TP=$TP"

echo "len=${#TP}"
#exit 0

if [ ${#TP} -gt 0 ]; then

echo "its executable"

for i in $TP ; do ( xm shutdown $i; echo "stop guest $i"; sleep 3 ); 
done
sleep 3
/etc/init.d/xendomains stop

fi

exit 0
EOL

----------- example use -------------
> sudo ./down_xm.sh
TP= 12 11 10 9
len=11
its executable
stop guest 12
stop guest 11
stop guest 10
stop guest 9
Shutting down Xen domains            done

Some issues got fixed, but I think they are currently only in xen-unstable,
although they can be
easily backported.

BR,
Carsten.
