[libvirt-users] Accessing xenstore from libvirt

Hi, is it possible to access xenstore through libvirt? Or at least any other programatic means other than calling xenstore-read/write through shell? I understand it is somewhat of a security risk but still... Thanks, Marin

No, we don't expose this kind of capability at this time Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

And I don't think we ever will support generic xenstore read and write through libvirt. xenstore is uniquely Xen :-). In the old xen driver, xenstore is used (along with xend and hypercalls) to implement the overall functionality of the driver, but there are no specific APIs for reading from / writing to xenstore.

If libvirt did ever want to support passthrough of xenstore reads/writes, it would have to be in a separate libvirt-libxl.so library, in the same way that we allow passthrough of QEMU monitor commands via a separate libvirt-qemu.so library.
