[Libvir] suspend/resume == pause/unpause?
'xm' uses pause/unpause. libvirt uses suspend/resume. It seems they are the same. IMHO this should be made explicit in the documentation (I'm looking at the python help for libvirt). Diwaker -- Web/Blog/Gallery: http://floatingsun.net/blog

Take any OS book, you will see suspend/resume defined. Ask a laptop user what it means to suspend and resume, it's understood. My goal is not to copy Xen API and make it LGPL, my goal is to make a simpler API that more people can use. And IMHO the description are quite precise, I expect only a small fraction of the potential libxvirt users to actually have gone though Xen API 'descriptions'. http://libvirt.org/html/libvirt-libvirt.html#virDomainSuspend "Suspends an active domain, the process is frozen without further access to CPU resources and I/O but the memory used by the domain at the hypervisor level will stay allocated. Use virDomainResume() to reactivate the domain." If you think it's ambiguous I take documentation patches !

It makes me wonder if the appropriate terms for pause/unpause and save/restore is really suspend/hibernate. Regards, Anthony Liguori
