Hi,

I would like to ask the proper or recommended way of upgrading xen...?

I started with 3.1.0 then upgraded to 3.2.1 but now I am not able to use the original system. Since I am not satisfied[*] with the current setup I would try to upgrade to 3.3.1 but it would be nice if something went wrong I could downgrade it to 3.2.x... It is a pitty that booting the previous xen image does not work because of the changed libs.

[*] The problem is that under heavy load in dom0 (or IO operation like performing the daily backups) I get a lot of "Time went backwards, etc." and sometimes (per 1-2 months) it crashes (freezes). The hw is a TYAN VX-50 w/ 4 Dual-Opteron 8220 CPUs and 4 500G WD RAID ED. discs (pairwise in software raid1, so the total capacity is ~1TB). Unfortunately the onboard NV SATA controller did not work under XEN so an ADAPTEC PCI card had to be installed.

So any hints or URLs are welcome,
--
Zsolt
