Hello
Is there an easy way to get supported feature (API) list in each driver?
The function would be to return a list which describes which APIs are
supported and which APIs are not.
Thanks in advance

No, and it's somehow painful. If unsupported you will get a specific
error code back though, so maybe that can be automated in some ways.
There is the manually maintained page for driver support at
http://libvirt.org/hvsupport.html
but being manual means it's often outdated :-\
Also there is some subtleties, for example on Xen the main driver is
actually implemenbted as a set of 3 sub-drivers for hv/xend/xenstore
so just checking for NULL values in the driver entry point is not
completely sufficient to assert support of a feature.

Indeed. I agree it is an easy way (not smart though).

There is not even entry for lxc!
Also there is some subtleties, for example on Xen the main driver is
actually implemenbted as a set of 3 sub-drivers for hv/xend/xenstore

Oh, I didn't know that. I though I could use the entry point.
OK, trial and error seems a easy and solid way.
Thanks for your explanation.
