Yeah, even esx needs VT enabled procs for 64bit vm support, but they can software emulate the 32 bit hosts which is impressive for the performance it gives. Xen flat out needs VT for any HVM guest, but the speed is very good. Once the community gets pv drivers for windows straightened out, it should be impressive, but if you don't need flat out throughput on your nic for example, it might still be viable. I am going to rig up a DR setup soon.
I am about to post to the Xen list to see if PCI passthrough devices still need special drivers to yield good throughput. jlc From: Webb, Brian (Corp) [mailto:[EMAIL PROTECTED] Sent: Thursday, January 10, 2008 8:42 AM To: NT System Admin Issues Subject: RE: Xen I haven't tried it, but Virtual Iron has a free version for smaller environments that runs on bare hardware. It needs a very recent processor with the virtualization extensions built in so it won't run on older hardware. It sounds promising. -Brian ________________________________ From: Reimer, Mark [mailto:[EMAIL PROTECTED] Sent: Thursday, January 10, 2008 9:06 AM To: NT System Admin Issues Subject: RE: Xen Along the same vein, I'm on a tight budget, and in my cursory research into virtual server programs, Xen was the only free one that ran on bare metal. The other free programs ran on top of another OS. Is this correct? Mark ________________________________ From: Joseph L.

Just curious if it has gained any real enterprise use yet. jlc ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
