Xen domUs on remote storage (iSCSI / NFS)

view story

http://www.linuxquestions.org – I'm tinkering with a Debian Xen dom0, curious about the ways I can host domUs. This is not production, I'm just learning. I'm considering a setup that centralizes all irreplaceable data on a box running FreeNAS, which can export iSCSI or NFS. If I understand correctly, iSCSI would allow me to layer LVM on top, which is the preferred way to run domUs for flexibility and performance. NFS would be used if I did a file-based VM setup, which I consider second choice. The way I *think* it would work best: Code:                         (HowTos)
