What would it take for me to mount the shares on the hosts, and export them to my VMs using v9fs, for instance? In practice, only one of my VMs will access a portion of the NFS at a time, and the host won't touch it at all, so I'm pretty confident that the VMs' VFS caching and locking won't be an issue. I understand that KVM can do v9fs exports using virtio and qemu[1], and I was wondering if this was possible with Xen as well, as Xen also makes use of qemu. Allegedly using virtio devices should theoretically be possible for HVM guests, but I'm not sure if this has been implemented in Xen's qemu. I don't have a preference for v9fs at all, so any hints or insights to similar solutions will be greatly appreciated. Yours, Jesper.
