Subject: [PATCH v2] Enhance kvmconfig

Dropped BALLOON entries as suggested by Borislav Petkov. Tested.

This was tested only on Hetzner CX10 VPS. I don't know how recent KVM
server stuff they use.
Tests & reports from anybody else are appreciated.
I guess some of added options may be not strictly necessary or make not
that lot of sense as enabled by default, feel free to ask me to drop
some and test how it works.
Thanks.

"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.
