I have posted in http://vireso.blogspot.com my notes about installing Centos5 (from DVD image) into DomU on OpenSolaris Xen (xen-nv66-2007-06-24). Using OpenSolaris for Dom0 gives such advantage as zfs zvols for "phy" devices in DomUs, so zfs snapshot & zfs send gives you incredible fast and convenient full/incremental backup/restore of full DomUs. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''m using zfs-fuse, and quite frankly, performance sucks. Convinient backup/restore feature from zfs will be great if only it has (at least) half the performance of ext3 over LVM.

Native zfs, according to available in the net benchmarks and to my experience, are very fast. I don''t understand how they manage to do compression on the fly, checksum computation and verification and at the same time throughput and seek time better than that of ext3 on the same hardware. -- Sergey. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
