<div dir="ltr">The patches apply to Qemu 2.5. You will need to recompile it after applying the patches. See your distro's help section on working with source files. You should be able to add these to the RPM/DEP/Ebuild scripts easily. There are script files inside RPMs and DEBs that tell rpm/deb how to build those packages, thus editing that will compile the patches in for you and build the installable RPM/DEB.<div><br></div><div>The following patches need to be applied in the order listed. They are taken from Gerd's qemu work branch.

The patches make the keyboard/mouse directly available on the guest as a real device. This way I have one keyboard and mouse for both host and guest. The technical bit is that the input buffers are forwarded to the guest. Synergy is nice but there is lag with that. These patches are real time! I play the latest AAA games too. I haven't noticed anything. It doesn't hurt to try. I can post my libvirt config if need be.
