[one-users] Non clonable readonly shared OS image?

[Ismael Farfán]

Hello list

I have a single OS image that I want to launch multiple times, since
it's in a global directory I configured it with tm_nfs only and declared
the disk like this:

DISK = [
    source = "/shared/squeeze.img",
    target = "hda",
    driver = "qcow2",
    readonly = "no",
    clone = "no" ]

The idea of course is that the image doesn't get copied again and
again every time I launch another instance, thereof saving time and
resources...

If I declare it with readonly=no the VM will start ok, but starting it
multiple times corrupts the filesystem, and if I set it as readonly=yes,
the VM will not start at all.

I pretty much have the minimal environment after following the
quick start guide and the tutorial from FutureGrid.

Is there something I can do to get the desired behavior?

Regards
