I have 2 machines, 1 storage, 1 vm host. I can present a zvol to the vm host over iscsi, which would then format it as a block device. Then, running ON that storage will be VMs, some of which might be FreeBSD, or Linux.
Having 3 nested levels of ZFS seems brittle somehow. If I carve out a zvol on the storage host , and the VM host formats that block device as ZFS, and then I run VMs inside that vm host, and those vms format THEIR virtual storage as ZFS, I feel like its going to be ARC madness.
Is there a simpler way? Maybe skip the formatting of the iscsi block device as ZFS, and let the storage server manage the real storage, and each VM manage its own virtual storage?
