[clug-talk] Virtualized Server Question

2013-09-17 Thread Andrew Robinson
Hi, I was wondering if anyone had experience with virtualizing servers and what there preference was for either ESXI or Virtualbox.  I should mention that one of the VM's will support a hard drive of nearly 4TB (currently in software raid 5) and growing.  Hardware that this server will be resid

This looks like a pretty interesting alternative to ESXI.  One thing I couldn't see on their website however, is does this install to a hard drive or can it be installed to a USB key like ESXI? -Original message- From: Jon Copeland  Sent: Tuesday 17th September 2013 15:04 To: CLUG Genera

I don't have specific experience with Proxmox, but I would not run KVM off a flash drive. Just like any other Linux process, KVM will malloc() and the kernel will swap if it needs to. Anand. On Tue, Sep 17, 2013 at 3:42 PM, Jon Copeland wrote: > Unsure which you're referring to but Proxmox c

I think we're on the same page here. Virtualbox is not designed for server I/O. It's fine for desktop VMs, but doesn't do well for running servers as guests. Both Xen and KVM run inside a Linux host like Virtualbox, but do better with servers as guests. Check out the demo for this KVM frontend:

Sorry I guess I should have been a bit more clear, I just forget the proper terms at the moment :)  ESXI would be the host running the various different VM's, or I would be running another os (say scientific Linux) with virtual box on top of it, running the VM's.  I'm trying to get a sense of th

Hi Andrew, If you're looking for an open source alternative to ESXi, it's not Virtualbox. Even running headless, it's not in the same league for server performance (nor was it designed to be). Look at KVM or Xen instead. I've got about a dozen of those Supermicro servers running at various site

Look into Proxmox (www.proxmox.com). It uses KVM so has a solid stability reputation and has a web UI much like ESXi so it's ridiculously simple to use. I've got it deployed at two sites and have experienced absolutely zero problems. The hosts run a variety of Windows / Linux and Unix VM's. As f

First I have to disagree with the suggestion to use a SAN/NAS. At this small size it does not make sense. If you have 4 or less VM Hosts then direct attached or Fiber Channel makes more sense when you consider cost, performance, and reliability. I have seen far too many cases of 3 or 4 hyperviso

Unsure which you're referring to but Proxmox can run off a Flash Drive. /.j On Tue, Sep 17, 2013 at 3:27 PM, Andrew Robinson wrote: > ** > > This looks like a pretty interesting alternative to ESXI. One thing I > couldn't see on their website however, is does this install to a hard drive > or
