I have seen the documentation saying to build an empty VM with slightly more space for each volume than was on the physical server, then use clonezilla to create an image of the server, then import it. That seems ok, but I'm hoping someone out there has more real-world experience in doing this and can share if they did it differently, or encountered any pitfalls.

As my environment matures, I am moving from "Hey I have 1 physical server with everything on it" to "Let's use a hypervisor and spin off services onto their own." When the base OS is P2V'd, I'll be able to have 2 hypervisors and start implementing HA. I've been using this system as a scratchpad and dev box for 10 years and would love to just migrate it over.
