I currently have a OpenSolaris installation with a ~1Tb RaidZ volume made up of 3 500Gb hard drives. This is on commodity hardware (ASUS NVIDIA based board on Intel Core 2).

I'm wondering whether anyone knows if XenServer or Oracle VM can be used to install 2009.06 and get given physical access to the three SATA drives so that I can continue to use the zpool and be able to use the Xen bits for other areas.

I'm thinking of installing the JeOS version of OpenSolaris, have it manage just my ZFS volume and some other stuff for work(4GB), then have a Windows(2GB) and Linux(1GB) VM (theres 8Gb RAM on that box) virtualised for testing things.

Currently I am using VirtualBox installed on OpenSolaris for the Windows and Linux testing but wondered if the above was a better alternative.

Essentially,

3 Disks -> OpenSolaris Guest VM, it loads the zpool and offers it to the other VMs via CIFS.
