I use qemu to run multiple virtualized machines on a single beefy (32-core) headless box; including a shared build-server, and my own remote-workstation.
I got sick of trying to figure out which thing I needed to click in virt-manager to get it to pass the flags I wanted, so I wrote my own minimal qemu-wrapper that covers all of the functionality from libvirt that I care about (vCPU pinning, binding to NUMA nodes, running as non-privileged user), and integrates better with the other system (systemd) monitoring than libvirt does. https://git.lukeshu.com/systemd-qemu/

I'm also involved with the Parabola GNU/Linux-libre distribution. Qemu user-mode emulation is essential to our support of non-x86 platforms (ARM and PPC). It lets us run cross-architecture chroots without a full-blown VM.
