Oddly enough, after downgrading seabios to version 1.7.3, I'm able to boot FreeBSD on the Ubuntu hosts without issue. I downgraded like so: apt-get install seabios=1.7.3-1ubuntu0.1~cloud0 No other packages (namely, libvirt/qemu/etc.) were downgraded as a result and I do not see any dependency issues, so it looks like this will be the workaround for now. I suppose I should make my situation know in that bug report, eh?

KVM filesystem sharing
Hello list. I wanted to ask if anyone has been able to make filesystem mounting work under a FreeBSD guest? For example, I've added the following to the guest's xml config using 'virsh edit': filesystem type='mount' accessmode='mapped' source dir='/tmp/shared'/ target dir='tag'/ /filesystem However, I don't know how to mount the above from within the FreeBSD guest. That which is instructed to do so on Linux guests does not work on the FreeBSD guest: root@freebsd9-test:~ # mount -t 9p -o trans=virtio,version=9p2000.L tag /mnt/shared/ mount: tag: Operation not supported by device The hosts OS is Ubuntu 12.04 LTS.

Perhaps you could try to use NFS instead? Generally speaking, why do Linux folks use 9P? Thanks! I'm thinking I may use guestfish instead to accomplish what it is I was wanting to do. I've never personally used 9P, but thought it might be a way I could use to get around a problem I've run into.
