Subject: [PATCH v3] Enhance kvmconfig

From: Andrey Utkin <andrey_utkin@...tmail.com>

"make defconfig kvmconfig" is supposed to end up with usable kernel for
KVM guest. In practice, it won't work for e.g. Hetzner VPS (KVM-based)
unless you add these options.

v3: dropped VIRTIO_MMIO stuff as suggested by Paolo Bonzini. Tested.
