I've got HVM GPLPV and nonGPLPV based hosts running in XEN, and they work great - all block-device backed. I also only use Debian for Dom0 because the package is good and I know Debian better than anything else. I've totally eliminated Hyper-V, as it's been far too slow. I do have some Virtuozzo stuff for the native-performance virtualization, but the license isn't free which means I'm picky about what I used it for. :) Best Regards Nathan Eisenberg Sr. Systems Administrator Atlas Networks, LLC support@xxxxxxxxxxxxxxxx http://support.atlasnetworks.us/portal -----Original Message----- From: xen-users-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-users-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Fajar A.

If it's THAT slower, then I can tell you this much : you'll be happy using Xen IF you : - use block-device (disk, partition, LVM, zvols, etc.) as domU storage, and not file-backed (raw, qcow, vmdk, etc.) - you install GPLPV It should give at least twice the I/O performance of vanilla HVM for Windows guests. Also note that last time I check using 1 CPU for domU yields higer I/O performance compared to SMP, so if your domU is I/O intensive you might want to stick with 1 CPU. As for dom0 distro I'm using RHEL5.3 (Centos should be the same), with xen rpms from http://www.gitco.de/repo/ (if I need to use the latest Xen version). They've been stable, and easy to install and manage. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
