libvirt users - Jun 2010 - How to get supported feature list in driver

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but being manual means it's often outdated :-\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.
