Something more that I discovered today:
=====
root at tinello:/etc# dpkg-query -W qemu-kvm
qemu-kvm        0.12.5+dfsg-5+squeeze10
root at tinello:/etc# virsh list
 Id    Name                           State
----------------------------------------------------
 1     tinello-xp.pca.it              running

root at tinello:/etc# virsh destroy tinello-xp.pca.it
error: Failed to destroy domain tinello-xp.pca.it
error: Requested operation is not valid: domain is not running

root at tinello:/etc# apt-get -t squeeze-backports install qemu-kvm
[...]
The following NEW packages will be installed:
  ipxe-qemu libiscsi1 libspice-server1 sharutils
The following packages will be upgraded:
  openbios-ppc openbios-sparc qemu-keymaps qemu-kvm qemu-system qemu-utils seabios vgabios

Setting up qemu-kvm (1.1.2+dfsg-5~bpo60+1) ...

root at tinello:/etc# virsh list
 Id    Name                           State
----------------------------------------------------

root at tinello:/etc# virsh start tinello-xp.pca.it
Domain tinello-xp.pca.it started

root at tinello:/etc# virsh list
 Id    Name                           State
----------------------------------------------------
 2     tinello-xp.pca.it              running

root at tinello:/etc# virsh destroy tinello-xp.pca.it
Domain tinello-xp.pca.it destroyed

root at tinello:/etc#
=====

So there was a problem in recognizing domains with the old qemu-kvm.
Please note that I now remember that I have seen the above message in
the past, but unfortunately I did not actually pay attention.

Still true.

Thx, bye,
