It draws attention to me that I didn't have this problem with
qemu-kvm-0.12.0-rc2 but after updating to qemu-kvm-0.12.1.1.

Mmmm... thinking a little, I made the update to see if with 0.12.1.1 no
longer had the problem with the e1000 network interface in OpenBSD.
Therefore, I only shutdown an boot this VM and not all. Could it have
caused that increase in the swap usage?

In both cases the used version of kernel was the same.

It doesn't have:

root@ubuntu:~# ls /sys/module/kvm_amd/parameters/
nested  npt

root@ubuntu:~# uname -a
Linux ubuntu 2.6.32-dgb #1 SMP Mon Dec 14 06:18:06 ART 2009 x86_64
GNU/Linux


Thanks for your reply.

Daniel
