[nlug] Re: State of Open Source Virtualization .. not a rant or flame war
I would assume you are talking about the processor extensions like Intel VT (for IA32) and VT-i (for IA64) or AMD-V (I think that's their name for the concept). As I'm sure you know since you are probably using the same laptop as I am, the Dell D830s don't come with a processor that supports it. If I were doing this for real hosting in a data center (as opposed to just having multiple dev environments to carry around), I'd definitely look for host hardware that supported hardware assisted virtualization. That adds another interesting layer to the comparison of options - it's possible that one hypervisor might perform better than another without hardware assistance, but the results might reverse with the hardware assistance.

[nlug] KVM Questions
OK, the discussion about virtualization has gotten me thinking. I have an old box here that i use as a home server and such.. the hardware is dying on it.. (900 mhz AMD K7 and other hardware of that era) so i am buying a cheap barebones kit to replace it. I have been wanting to play around with some of this virtualization and migrating between machines (this new server and my desktop) KVM's website says that it can be done if the image is stored via a NFS share.. which i can do through my ReadyNAS.. The question is.. even with it being a gigabit network.. is it insane to try and run a VM and use a NAS for the storage of the actual machine? Will the file IO be noticably slow and end up being something i have spent some extra cash to get going and then end up not using? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups NLUG group.

[nlug] Re: State of Open Source Virtualization .. not a rant or flame war
Actually Rob, I do almost all my virtualization on my Macbook which does support the Intel VT extensions. Also, my client work laptop which I use much more than my company laptop supports the Intel VT extensions. I admit I have been doing virtualization much more for personal reasons rather than business reasons. This means that I am working on development environments rather than production and don't have the need for moving a running Virtual Machine from one piece of hardware to another. So take it all with a grain of salt. MAIH..
