yes, sorry, locatime is not what I meant. The other mandatory option is "-no-
kvm-pit".

ACPI modification is done. But, the mandatory options "-tdf" and "-no-kvm-pit" 
cannot be add. And if you disable ACPI without these options the virtual 
machine freeze.
I ask for a <netbsd/> flag in the <features> section for giving the good 
arguments to qemu-kvm. 
Libvirt is the frontend, so it have to adapt, isn't it ?

No, there isn't a "NetBSD 5.0" type, but, currently, it is useless because 
libvirt can't run NetBSD with kvm  :(.
