Jim,
What would be the right thing to do for this? The intention is for osstest to skip migration tests when that feature is unimplemented by the toolstack/xen/arch combination.
It looks like the output of "virsh capabilities" indicates migration: <migration_features> <live/> <uri_transports> <uri_transport>tcp</uri_transport> </uri_transports> </migration_features> is that the right place to look?
Yes.
Will this capability be automagically suppressed on ARM until we implement it?
Unfortunately, no :-/. Currently, the libvirt libxl driver will include <migration_features> and call save, restore, and migrate regardless of arch.
FYI xl uses LIBXL_HAVE_NO_SUSPEND_RESUME to figure this out...
Ah, interesting. Thanks for the tip. I'll need to add similar logic in the libxl driver.
Something like the attached patch (compile-tested only). You'll need an updated libvirt.git master to apply cleanly. Regards, Jim
