Hello all,
The following feature page describes the engine adjustments needed for new SPICE features.
Al in all this looks good, some remarks:
* WRT multi monitor support for RHEL, the latest RHEL xorg-x11-drv-qxl and spice-vdagent packages do support multi monitor support using multiple cards in Xinerama mode. We are waiting for a RHEL-6 z-stream update to fix an x11-xorg-server-Xorg bug which atm makes the mouse unusable in this mode wants this lands, multi-monitor support this way should be available for RHEL-6.2 (and later) guests. The same holds true for Fedora guests, although I don't expect the necessary Xorg changes to be available for versions older then Fedora 17. The driving multiple monitors from a single qxl device support OTOH is still a long time away, likely 6 months or so.
The idea behind this support is to have it on a single PCI card, and not on multiple ones.
Right, I understand, but my point is, that current RHEL (and other Linux distro based) hypervisors as well as guests do not support the multiple monitors on a single PCI card setup, but they *do* support the multiple monitors, with each a separate PCI card setup like we also do for windows. This means that we may want to enable multiple monitor support for Linux guests *now* using the same code paths / method as for windows guests and then later, for vms where both the guest and the cluster support the multiple monitors on a single PCI card setup, use that instead. Which is not something which the wiki page reflects. Regards, Hans
