In case anyone is looking for "real-world" examples of Xen in use, I thought it might be helpful to post a summary of our experience. We currently have three Xen virtual servers running on a SuSE 10.1 Xen host for about two months now. The virtual servers comprise two SuSE 10.1 machines and one SLES9 machine (booting a SuSE 10.1 Xen kernel) running on lvm partitions. The vms perform as mail/groupware, file, web and utility servers for us and a number of our clients. We have successfully migrated these virtual machines across physical hardware manually, via rsync while the virtual hosts were powered down (by mounting the lvm partitions supporting the vms on the host OSs on both ends of the rsync). We plan on getting a SAN at a later date and then we'll test the Xen vm live migration tools. Hardware is an HP DL360G4p w/ 2 x 3.0GHz/2MB CPUs, 6GB RAM, and 2 x 146GB 15K disks. We have a JBOD attached for backing up the vms. Hoping lvm_snapshot gets fixed in the 2.6 kernel RSN, too... Since we tend to keep servers running for a long time, we have a second identical DL360 that we are now building up with SLES10 Xen, to consolidate and replace the existing vms. Ideally, we'd like to have the two physical servers be a cluster, but are nervous about which file system to use as we've heard some horror stories... If anyone has any questions (or clustering tips!), please don't send me a private email; post them here.
