hm, this patch doesnt seem to work, qemu gives me:

Could not create KVM context

it comes from:

3064 ioctl(3, 0x4004ae0b, 0) = 0
3064 ioctl(3, 0xc004ae0f, 0xbff8bd98) = -1 E2BIG (Argument list too long)

but i have an older (2-weeks) qemu drop from branches/release/qemu - is
that one supposed to work?
