Subject: [PATCH] Add a qemuMonitorGetCPUDefinitions method for QMP
query-cpu-definitions command
https://bugzilla.redhat.com/show_bug.cgi?id=863115
Add a new qemuMonitorGetCPUDefinitions() method to support invocation
of the 'query-cpu-definitions' JSON monitor command. No HMP equivalent
is required, since this will only be present for QEMU >= 1.2
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
(cherry picked from commit 2ecec6e2064c7ae6ec236cd9d392fa9c46390f84)
