[Qemu-devel] [PATCH v2 for 2.6 0/5] QMP wrappers for VM snapshot operations

["Denis V. Lunev" <den@openvz.org>]

EFI based VM with pflash storage for NVRAM could not be snapshoted as
libvirt configures storage as 'raw' and writable. OK, this is a libvirt
problem.

Another problem is that libvirt can not detect this failure at all
as it uses HMP for this operation. This create snapshot/delete snapshot
sequence passes silently.

The patchset adds QMP wrappers for the purpose.
