How does the management application learn the set of valid mountpoints arguments it can pass to this command? Shouldn't there be a query counterpart that asks the guest to return the full list of mountpoints that it can support freezing? In the case of guests that are all-or-none, like Windows, the query command would return an empty list to make it obvious there is no ability to freeze just a subset. In returning a list of mountpoint names, it might also be nice to correlate which names map to which devices (it can be a many:many mapping, thanks to things like RAID setups in the guest). > This would be useful when the host wants to create partial disk snapshots. > > Signed-off-by: Tomoki Sekiyama <tomoki.sekiy...@hds.com> > --- > qga/commands-posix.c | 17 ++++++++++++++++- > qga/commands-win32.c | 3 ++- > qga/qapi-schema.json | 4 ++++ > 3 files changed, 22 insertions(+), 2 deletions(-) > -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
