[OpenIndiana-discuss] cloning an OI system to VDMK

[Daniel Kjar]

If I zfs send into the distro-const that I just installed on
virtualbox can the source server keep running and do I have to livecd
boot the VM I am moving the pool to or can that be up while I send the
pool?  I think I like the zfs send route better from an armchair
perspective.

> You might have some luck starting the VM using an ISO image to get networking there and make an rpool, and then zfs-send the original machine's datasets recursively to the new one. After that you can enable the rootfs dataset and get the loader or grub to boot it up, and probably fiddle with various /etc/ files to address hardware changes.
