I mostly do that and have done for over 20 years now. My desktop is essentially a moderately powered thin client (currently a 2011 iMac27 with 2 27" thunderbolt displays running Beowulf). On the server side : - A Dual head windows 8 VM for Autodesk products & MS Office. - A Dual head windows 10 VM for newer Autodesk products that won't run on Windows 8. - A Debian wheezy / xfce VM for a specific older version of Openoffice. - A Windows 8 VM with a CCTV server. - A Devuan Ascii / XFCE VM for Peer to peer. - A Devuan Ascii headless VM for Cacti, HLI to the HVAC system and some general development and plumbing - Numerous VMs with specific build configurations for embedded software. The other thing VMs are good for is tying up Scam call-center workers. "My windows is full of viruses you say? And you can help me with that? Brilliant, just let me sit down and start my computer up" (spins up a fresh clean windows VM I prepared earlier) Win4lin, bochs and sheepshaver were brilliant, then qemu came and conquered. I can't imagine ever running Windows on the bare metal again. Between spice and rdp, there's not much you can't do.
