libvirt users - Feb 2012 - virt-install: "ERROR Host does not support any virtualization options"

Hello,

I have a problem with virt-install. I want to use it to create my vm and 
manage them. But whenever I execute the virt-install cmd I get the error 
msg mentioned in the subject.

Here are some more informations:

  </capabilities>



I have no clue what is going on. I have kvm compiled into my kernel. 
Normal "kvm" commands are working. Intel VT is enabled in the bios.


Any thoughts on this one?


Kind regards,

Do you have qemu installed? Under what paths?
Libvirt tries to find qemu-kvm under PATH or /usr/libexec/;
then kvm and qemu-system-* under PATH;

What about /dev/kvm - is it accessible?

Please, provide libvirt logs as well.
