Hello, sorry if these questions have been answered before but please excuse me, I''m new to xVM :) Anyway I have been using Linux/Xen for quite a while and am very familiar with it. I am very interesting in changing to OpenSolaris/xVM for the primary reason of being able to easily leverage the ZFS filesystem and thin provisioning for better storage efficiency. 1) Is this ZFS thin provisioning using locally attached disks a ''reliable'' method of storage allocation, i.e. we should not expect fragmentation or performance that degrades over time? 2) Is it expected that performance will be the same as when using a Linux Dom0 (as I assume the core Xen hypervisor will be the same), ultimately most of my guests will be Linux based 3) What version of OpenSolaris/xVM is currently recommended for stable-ish use? :-) Currently I''m using Xen 3.3 so I have no need for any 3.4/bleeding edge features. Thanks in advance for all the comments :-) -- This message posted from opensolaris.org
ZFS Sparse Volumes (Thin Provisioning) is the only way to fly, imho. I do all of mine that way. Performance has never been an issue of concern, although I haven''t done a comprehensive bench test. As for Linux dom0 vs OpenSolaris dom0 performance, I can''t say. I''m only using Solaris. As for stability, my personal preference is for SX:CE B121 which was when the integration of Xen 3.3 happened. Releases prior to that (such as OpenSolaris 2009.06 which is B111 unless upgraded) I''m not as fond of. The stability from 121 has been pretty solid, although I highly recommend disabling the Intel IOMMU feature if you have it. benr. -- This message posted from opensolaris.org
