It's on the 'todo' list to add to 'xm info'. Patches welcome :-)

Thanks,

If you want just disturgish between 2.x and 3.x you can check whenever
/proc/xen/grant is present or not (new in 3.x).

I'm 100% new to python, but I've figured out where to add code to make
this show up in xm info. (Already tested with dummy data.)

Can anyone tell me what object or function I could squeeze to get the
Xen version number?

Also, what should the label be called? I started with "xenversion", but
wasn't sure if it should be xen or xend.

Ian, is this what you named "xm --version" in todo list? if not, what
it is? (so vague!
)

it is not that trivial. you must hack up here and there... for
example, it is necessary to extend python wrapper for this.

no, xen and xend are different things: xen is hypervisor, and xend is daemon.

btw, i am hacking this, and almost done. will post a patch soon.

Yep, though I actually prefer the idea of adding it to 'xm info'. We
should report the xen version, tools version, and dom0 linux version.

Yep, you'll need to export it through the hypercall interface.

Cheers,
Ian

yes, it is better to track everything via "xm info". and it is very
nice to have tool version reported. but i wonder where to get this
version. just assign it somewhere manually in xm code?

Seems reasonable.

Best,
