This can sound a little bit paranoid but I really have a doubt that my configured libvirt+kvm uses any hardware acceleration in debian. I setuped it with this guide. in fact i've checked already, kvm-intel module is loaded for sure. But inside vm with freebsd for example, I have such a huge lag while, for example: installing OS, extracting port tree with csup, and of course compiling ports also. Resources are pretty big on that machine: 4 cores of cpu and 4gb of ram. I can confirm that I had same setup with proxmox on debian, before setuping libvirt manually on the same machine. So I do know how fast guest must be. So it's really out of question about hardware issue, I mean OVH hosting states that: Intel Core i5-2400 4x3.1+ GHz 6 Mb L2 - QPI 5 GT/sec is ued and virtualisation is: VT Instructions
So as I said this setup worked before. The only thing that, maybe, I missed kernel module configuration, but kvm-intel is loaded, and my friend checked that libvirt uses it too. so please tell me what I did wrong , maybe guide giving wrong steps..? maybe freebsd guest doesn't support something? if you need some additional information please write in comments. Maybe it's worth to mention that I've updated kernel, since new installation of debian was done (on host). Maybe loaded module can't find something related to kernel.. anyway I'm really puzzled what to do next.
this configuration was used to create vm:
# virt-install --connect qemu:///system -n bsd -r 4096 --vcpus=2 --disk path=/home/vm/hdd/bsd.img,size=100 -c /home/vm/iso/FreeBSD-8.2-RELEASE-amd64-disc1.iso --vnc --noautoconsole --os-type unix --os-variant freebsd7 --accelerate --network=bridge:br0,mac=02:00:00:a7:66:32 --hvm
