I've been a fan of virtualiztion since VMware gave away VMware Server for free. I've upgraded the host OS on my desktop twice and I have been able to remain productive as all my work resides on a separate disk and in virtual machines.
However, since VMware Server 2.0 was released, I've been actively looking for alternatives. Coincidentally, our hosting provider will be implementing Xen soon for LAMP deployments and I thought this to be the perfect excuse to at least install and try it out.
Well, so far I'm stuck because I can't boot to X windows on the Xen Kernel because I'm using nvidia drivers. I'm sure there is a solution already somewhere but I'm going to stop for now and leave it as something to look forward to solving over the coming weekend ;-)
