Ok, I finally got it working.

The problem was 32/64 bits issue. I'm so used to 64bits kernel and 32bits
userland - not a single thought occured to me that this might be problematic
of some sort. I was always trying 32bits kvm usermode tools with 64bits
kernels. Now I booted a 32bits kernel, and it finally worked. Oh well.
