[libvirt] suspend/hibernate guests on host shutdown

2009-05-26 Thread Gerry Reno
There are times when you just have to reboot the host machine to clear a problem or after some maintenance. The problem right now is that this forces all the guests to go through an entire reboot as well. What would be good is if the host shutdown would invoke a suspend/hibernate of the guest

Hi, Probably the easiest way to solve this is to get rid to of the OpenNebula client library. So we do not have the license issue and, as Daniel said, we do not have to include the C++ dependencies. We'll try to send the patch ASAP. Regards Ruben On Tue, May 26, 2009 at 3:16 PM, Daniel P. Ber

The patches for secure migration raise an interesting question wrt the handling of data streams and their effects on the internal driver API and the public API. Although the migration helper APIs are not technically public, they do map onto the remote wire protocol and as such we have the same long
