developers ?
Or should I try to contact them ?
regards
Danny

Solaris least privilege support
On Solaris dom0, virtd runs as a privilege barrier: all libvirt
connections are routed through it, and it performs the relevant
privilege checks for any clients.

from the post-install script:
Installing : libvirt
ln: creating symbolic link `/etc/libvirt/qemu/networks/autostart/default.xml': File exists
