[libvirt] [PATCH v2 0/3] Update VRDE server port handling.
v1: https://www.redhat.com/archives/libvir-list/2017-October/msg00421.html Changes since v1: * separate out the patch that drops VBOX_SESSION_OPEN/CLOSE macros. * reverse logic to check for rdp.autoport instead of rdp.port to avoid handling port = -1 * do not set rdp.port = -1 if vboxGetActiveRdpPort returns -1 and add more verbose code comments to clarify the logic Dawid Zamirski (3): vbox: Remove old unflexible macros vbox: Make autoport set RDP port range. vbox: Read runtime RDP port and handle autoport src/vbox/vbox_common.c | 3 +- src/vbox/vbox_tmpl.c | 159 ++++++++++++++++++++++++++++++------------ src/vbox/vbox_uniformed_api.h | 2 +- 3 files changed, 118 insertions(+), 46 deletions(-) -- 2.14.2

VirutalBox has a IVRDEServerInfo structure available that gives the effective runtime port that the VM is using when it's running. This is useful when the "TCP/Ports" VBox property was set to port range (e.g. via autoport = "yes" or via VBoxManage) in which case it would be impossible to get the "active" port otherwise. --- src/vbox/vbox_common.c | 3 +- src/vbox/vbox_tmpl.c | 134 +++++++++++++++++++++++++++++++----------- src/vbox/vbox_uniformed_api.h | 2 +- 3 files changed, 104 insertions(+), 35 deletions(-) diff --git a/src/vbox/vbox_common.c b/src/vbox/vbox_common.c index 92ee37164..d542f2b76 100644 --- a/src/vbox/vbox_common.c +++ b/src/vbox/vbox_common.c @@ -3326,7 +3326,8 @@ vboxDumpDisplay(virDomainDefPtr def, vboxDriverPtr data, IMachine *machine) if (VIR_ALLOC(graphics) < 0) goto cleanup;

Yep this should be removed - it's a left over from my old internal patch [1], that I forgot to remove when preparing for upstream submission. It was originally preceded with OpenExisting (aka LockMachine) to get the IConsole - the new patch does it internally in the vboxGetActiveVRDEServerPort function. https://github.com/datto/libvirt/commit/a3cb830bfce10b1a614c18a6ac50783 45433d900#diff-747d3af65e7ac81a564b7cb4fcd01eb6R3516 Thank you, Dawid
