Davíð Steinn Geirsson b4f45de7a3 debug(gpu): add diagnostic logging to build_rutabaga for virgl2 debugging 
Log rutabaga configuration, DRM render node accessibility, and
EGL-relevant environment variables during GPU backend initialization.
This helps diagnose why virglrenderer may fail to use hardware
acceleration in standalone vhost-user GPU device mode.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
