[ovirt-users] Q: Hybrid GlusterFS / local storage setup?

Hello all, I'm thinking about converting a couple of old dual Xeon V2 workstations into (yet another) oVirt setup. However, the use case for this cluster is somewhat different: While I do want most of the VMs to be highly available (Via 2+1 GFS storage domain), I'd also want pin at least one "desktop" VM to each host (possibly with vGPU) and let this VM access the local storage directly in-order to get near bare metal performance. Now, I am aware that I can simply share an LVM LV over NFS / localhost and pin a specific VM to each specific host, and the performance will be acceptable, I seem to remember that there's a POSIX-FS storage domain that at least in theory should be able to give me per-host private storage. A. Am I barking at the wrong tree here? Is this setup even possible? B. If it is even possible, any documentation / pointers on setting up per-host private storage? I should mention that these workstations are quite beefy (64-128GB RAM, large MDRAID, SSD, etc) so I can spare memory / storage space (I can even split the local storage and GFS to different arrays). - Gilboa
