[Xen-users] Run a script after creating a domain
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is it possible to run a script after creating a domain ? e.g. xm create -c /etc/xen/auto/domain ... after this, execute a script. e.g. /etc/xen/scripts/myscript.sh ... Any ideas ?

Excellent tool, you can run several hooks after creating domain, there are also "roles" you can assign to the dom during creation.

My solution would be to right a shell script: #!/bin/sh # /usr/local/bin/start-vm # if [ -z "${1}" ]; then echo "Usage: $0 domain; fi xm create ${1} if [ -x /etc/xen/${1}.sh ]; then /etc/xen/${1}.sh fi That will run "domain.sh" after starting "domain".

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 "> I think the OP was more interested in running a script after the > new domain had started - rather than after it had been created for > the first time" Yes that''s it, but I want to start it at system boot. Ubuntu starts all VM''s which configuration files located in /etc/xen/auto. I just want something automatic, rather than to initialize every VM in /etc/rc.local, but also thanks for the tip. - ---------------------------- Roberto Gonzalez Azevedo Steve Kemp wrote:> On Thu, Sep 14, 2006 at 11:47:51AM +0100, Tom Z.

Although you might not doing network-based stuff and so it might be misleading to do other things there, you could append the start of your script onto the network script. Another way would be to let the domain''s config file run a script with a python syscall at the end (have it not exactly in my mind how this should be done, so no example, sorry) of the config file, as config files are only python scripts.

I think then the solutions provided in my other post should work - they don''t use an additional external wrapper. BTW: I think it''s vif-script, not network-script, the latter is only run at xend''s start.

That means, the skript will not run if the domain is simply rebooted without destroying the domain. I ran into a similar problem while trying to make the scheduler parameters persistent (there is no config file parameter for that matter in 3.0.2). Until now i did not find any suitable way to solve that problem.
