Comments on: Virtualization Short Take #7 http://blog.scottlowe.org/2008/05/07/virtualization-short-take-7/ The weblog of an IT pro specializing in virtualization, storage, and servers Fri, 25 Jul 2008 14:38:35 +0000 http://wordpress.org/?v=2.1.3 By: Jack http://blog.scottlowe.org/2008/05/07/virtualization-short-take-7/#comment-37898 Jack Wed, 14 May 2008 15:43:25 +0000 http://blog.scottlowe.org/2008/05/07/virtualization-short-take-7/#comment-37898 Hello, read the article of GSNW, and I agree with the writer. However I come from a linux/Solaris background, and our VM of choice is XEN (generally speaking). Citrix owns the XEN group now, however the core is still open source, and from what I understand HyperV is based on XEN. I've personally used VMWare Server (not ESX) and compared it to XEN just to see, and it's hard to prove, but there are random slowdowns with VMWare. In XEN I never know it's a VM, in VMWare, I'm painfully aware. It's in this frame of thought where I hope M$ chooses the best VM platform out there, and for linux, it's certainly XEN (imho). Probably I cant configure VMWare perfectly, but the lack of direct drive usage or even bare partitions in VMWare is a major issue to me - that's just plain aggravating. Ah well, I don't do that much with XEN either, mostly use LVM for partition mgmt, etc. thanks for your column, looks like a nice blog in general.

In addition, you'll want to install VMware's paravirtualized drivers (called VMware Tools), which are comparable to the PV drivers offered by some Xen vendors (Novell, Citrix, and Virtual Iron spring to mind). I don't think that Hyper-V is based on Xen, although I do think they share a lot of architectural similarities. Somehow the idea of Microsoft basing their code on an open source project just doesn't seem to gel.... Anyway, thanks for reading and thanks for the comment! Jack,

It's probably done the rounds already, but: http://invurted.com/hypervisorcomp.pdf an interesting comparisom of Vmware and Xen. Great blog, by the way!
