Unfortunately we need a new API for that, since KVM only exposes one of the three resets. Also we need to clear the riccb and the PSW ri mask on a normal reset. And we need to set the short psw bit indication in the bios when doing a reset. Patches are also in my cleanup branch. v2 of the KVM patch for the resets will be posted soon.
