Hi, The QEMU machine vmport option allows to set the VMWare IO port emulation. This emulation is useful for absolute pointer input when the guest has vmware input drivers, and is enabled by default for kvm. However it is unnecessary for Spice-enabled VM, since the agent already handles absolute pointer and multi-monitors. Furthermore, it prevents Spice from switching to relative input since the regular ps/2 pointer driver is replaced by the vmware driver. It is thus advised to disable vmport when using a Spice VM. This will permit the Spice client to switch from absolute to relative pointer, as it may be required for certain games or applications. The following patch series allows to configure the vmport feature. The first version sent used a domain attribute, Daniel Berrange suggested to use a feature instead. I sent a second version that didn't receive reviews. Hopefully this one will stand more chances!
If there is *really* no other way how to check whether qemu supports the feature (specifying vmport= as part of the machine), ACK series with two adjustments mentioned per-patch.
