However, I just put a VM into production on a high traffic Samba deployment and performance is horrible. I could do better by hooking a USB stick to the workstation. I'm going to move the data for this VM over to the primary filesystem in the VM over the weekend, but I'd like to know why this isn't working very well. NFS is perfect for mounting volumes inside a VM, unless it just doesn't work.
