[libvirt] [PATCH 0/3]add 'policy' attribute for qemu vnc display sharing policy

These patches try to add a new attribute 'policy' to element graphics of vnc type. This attribute has three values: libvirt XML: <graphics type='vnc' port='5900' policy='force-shared'> QEMU commandline -vnc :5900,share=allow-exclusive Allows clients to ask for exclusive access which is implemented by dropping other connections Connecting multiple clients in parallel requires all clients asking for a shared session (vncviewer: -shared switch) libvirt XML: <graphics type='vnc' port='5900' policy='force-shared'> QEMU commandline -vnc :5900,share=force-shared Disables exclusive client access. Useful for shared desktop sessions, where you don't want someone forgetting specify -shared disconnect everybody else. libvirt XML: <graphics type='vnc' port='5900' policy='ignore'> QEMU commandline -vnc :5900,share=ignore Dompletely ignores the shared flag and allows everybody connect unconditionally Guannan Ren(3) [PATCH 1/3] qemu: new vnc display sharing policy caps flag [PATCH 2/3] conf: add 'policy' attribute to graphics element for vnc [PATCH 3/3] qemu: support share attribute and its values to -vnc docs/formatdomain.html.in | 13 +++++++++++-- docs/schemas/domaincommon.rng | 9 +++++++++ src/conf/domain_conf.c | 28 ++++++++++++++++++++++++++++ src/conf/domain_conf.h | 11 +++++++++++ src/libvirt_private.syms | 2 ++ src/qemu/qemu_capabilities.c | 12 ++++++++---- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 13 +++++++++++++ tests/qemuhelptest.c | 9 ++++++--- tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc-policy.args | 4 ++++ tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc-policy.xml | 35 +++++++++++++++++++++++++++++++++++ tests/qemuxml2argvtest.c | 1 + 12 files changed, 129 insertions(+), 9 deletions(-)
