To enable network with qemu-kvm, we had to disable the acpi and add other options like -tdf, -localtime ... Hmm, I would not expect BSD to need 'localtime' -...
yes, sorry, locatime is not what I meant. The other mandatory option is "-no- kvm-pit".
You can turn off ACPI easily enough, by leaving out the '<acpi/>' flag in the <features> section. The -tdf flag isn't something we have support for. It is not in upstream QEMU, only added in the KVM tree AFAIK, and is rather a hack. KVM should be fixed to 'just work' by default either by fixing the bug that prevents BSD working, or by making -tdf the global default.
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 ?
Currently, I have not found the way to do it with libvirt (and I don't think it is possible with virt-manager).
virt-manager doesn't tend to expose this fine level of control over individual features. Instead we have an OS type dictionary giving the defaults for these kind of things, particularly the acpi/localtime settings. I can't remember off hand if there is a Net BSD 5.0 OS type or not - if not file a bug against virt-manager asking for one to be added.
No, there isn't a "NetBSD 5.0" type, but, currently, it is useless because libvirt can't run NetBSD with kvm :(.
