[Xen-devel] [OSSTEST PATCH [RFC] 0/3] Series short description

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

OSSTest: allow for handling multiple guests at the same time

via the ts-debian-install, ts-debian-fixup and
ts-guest-{start,stop,destroy} test scripts.

The idea is to enable something like that:

 $ OSSTEST_JOB=test-amd64-amd64-xl
 $ export OSSTEST_JOB
 $ ./ts-debian-install host=tg03 debian1 debian2 debian3
 $ ./ts-debian-fixup host=tg03 debian1 debian2 debian3
 $ ./ts-guest-start host=tg03 debian1 debian2 debian3
 $ ./ts-guest-stop host=tg03 debian1 debian2
 $ ./ts-guest-destroy host=tg03 debian3

In fact, when wanting to use OSSTest for some fairly complex test
or benchamrk that involves more than one or two VMs, I think
it could be convinient to install, start, stop, etc., them like
this, rather than having to call each script for all the domains.

It should also save some time, when it comes, for example, to
starting domains, as the operation is first requsted for all of
them, and only after that we start checking wether they're up
(the idea being that when we start checking, after having started
the last one, the first one have probably finished booting).

It's going to be mostly useful in standalone mode, but
I guess it could allow to write more compact recipes too.

I tested this both as reported above and by issueing a full
`./sg-run-job test-amd64-amd64-xl'.

I can go ahead and do the same for other ts-* scripts but:
1) I don't think is that much relevant/useful to do something
   like this in, for instance, ts-guest-migrate or
   ts-guest-saverestore
2) given my limited perl skills, I though I better ask for
   some early feedback. :-)

Any comments are welcome.

Regards,
Dario
