Open Stack

Just realized that I sent this to Sean, but not the list...

Sean;

Thank you for that pointer to hw_video_model=virtio, that addressed the resolution issue!

Any chance you could point me at a metadata option that would tell libvirt to provide 2 monitor devices?  It looks like I need to send the max_outputs=2 to qemu, or libvirt or directly to virtio-vga (I'm not sure which) [1], though I don't see a way to pass that through in nova.virt.libvirt.driver [2].

As to how GoToMyPC works... I don't know, but I believe it captures the framebuffer.

i am not sure the resoltution that rdp or whatever GoToMyPC uses will
be affected by the use of vnc or spcice on the host. I think this is
related to the video model used in the guets unless GoToMyPC is running
on the host and connecting the the qemu process. thats not normally
something we would recommend but if its directly conecting to the qemu
process then the use of vnc or spice might be a factor

have you tried changing the video model to virtio for example, that
should enabel more resolutions in the guest. i know that usign RDP in a
windows guest with hw_video_model=virtio in the image does allow higher
resolutions and i think it enables multi monitor support too.
