Recommendations For Home Virtualization?
An anonymous reader writes "I'll have to upgrade my home computers sometime in the next few months and I'm thinking it's time to swallow the virtualization pill. Besides the ease of switching between Windows and Ubuntu, I'm looking mainly for the ability to save machine state in order to be able to revert to a known working state. Googling turns up mostly guides from 2009 and earlier. Is VMWare ESX pretty much the way to go? Performance does matter — not for gaming but I am heavily into photography, so apps like Lightroom and Photoshop need to run well. Thanks for any insight."
I have used VirtualBox quite a bit and I find it completely satisfactory. I have run both Win XP on Ubuntu hosts and Ubunutu on Win XP hosts and it has always worked very well. http://www.virtualbox.org/ I think it would do everything you want.
RHEL6 dumping Xen is actually a mistake. Not that KVM is bad, but Xen is actually really good and works well in production. The community is at fault for not trying to do more to integrate Xen into the kernel better.
But such is the way with open source. Dump a working solution in favor of an up and coming newbie with its own set of problems.
Use the export function. This will export the VM in OVF format, which is a portable format you can move to anywhere, even to vmware.
Export then import. It's easy.
I made an image for someone on my Windows 7 Ultimate 64 bit machine, so they could use it on their Mac. I exported it, they imported it, and everything ran flawlessly. They were delighted.
And yes, you can run a machine from the command line. I have OpenVPN Access Server in a virtual machine running on my Linux server. OpenVPN Access Server didn't want to run natively on one of my physical server, so I stuck it in a box. :) Xorg is not running on the server (for obvious reasons), so it just starts at boot time with: /opt/VirtualBox/VBoxHeadless -startvm OpenVPN
Serious? Seriousness is well above my pay grade.
