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.
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.
Indeed. I agree it is an easy way (not smart though).
There is the manually maintained page for driver support at http://libvirt.org/hvsupport.html but being manual means it's often outdated :-\
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 so just checking for NULL values in the driver entry point is not completely sufficient to assert support of a feature.
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. ozaki-r
