"OpenSolaris 2009.06 has been recently released. Since
ZFS offers a lot of flexibility and advantages as a storage
platform, many would be interested in running the opensolaris
stack. In this article I'll be installing OpenSolaris 2009.06
para-virtualized under a centos-5-x64 dom0. This setup has the
advatange of running OpenSolaris on storage controllers that may
not have native solaris driver support. Not that that would be
recommended, however, it might be useful for testing. So, let's
begin
"- Install a minimal Centos-5-x64 installation. I installed the
OS on a 20G partition, while the rest of the disk was formatted as
LVM partition for creating logical volumes for xen guests to live
on
"- Install the latest Xen stack. I will be installing Xen-3.4.
This is highly recommended since the bundled boot-loader pygrub has
the ability to mount ZFS block devices."
