I want to use my server machine (currently running FreeNAS) as a gaming box too. To do this, I'd install windows 7 on it, and run FreeNas as a virtual machine.
The role of the server is a file server. I'm using ZFS on its 6 1TB drives (2 parity drives).
I would set it up so that the VM would have access to the physical disks.
I was told that the virtual machine software would convert sync writes to async writes, and this could cause data corruption. Obviously I don't want that! Is there a way around it?
What other problems will I come across running a file server in a VM?
