Stop p!ss!ng on my Xen parade :)

So I wouldn't really need to have a spare server ready in case of failure. Ill probably take a look at xen sooner or later. Being a consultant its hard for me to support something that people cant understand. They can understand vmware, trading at 125/share owned by EMC ;) From: Joseph L.

And BTW, running an esx vm on anything but esx causes all the hardware to be redetected. Blah. Xen can do all the stuff esx can now, it's crazy. I like Xen as it leverages all the neat stuff Linux has to offer like LVM etc. jlc From: Benjamin Zachary [mailto:[EMAIL PROTECTED] Sent: Thursday, January 10, 2008 9:10 AM To: NT System Admin Issues Subject: RE: Xen You can drop VMware server on a really small Linux deployment, that would give you all free and on your o/s choice. Im not overly familiar with Xen and a couple of the others, but when you are looking at virtualization make sure you look at the ability to migrate, upgrade, recover, move, DR and all the tools involved with that. If you have a dead vmware server, for example, you could take VMware player, workstation, server, ESX, or any of the other products and copy in that vm and get back up and running. You can convert anything to esx,server,workstation,player using the free VMware convertor tool. So in a Xen scenario you would need two physical boxes, one for production and one 'hot' server in case of failure. You would want to maintain a hot copy of the server(s) that you could fire up. Unless you have another server already running one of the required o/s'es that you could put Xen on when failure occurs. Im sure other products offer similar functionality you just may want to see how it works and what your primary/secondary functions are for virtualization and how these needs are addressed.

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> ~
