 | Usage: you can run this script with any valid combination | 
 | of the following environment variables (in any order): | 
 |   KERNEL - the kernel image file to use | 
 |   ROOTFS - the rootfs image file or nfsroot directory to use | 
 |   MACHINE - the machine name (optional, autodetected from KERNEL filename if unspecified) | 
 |   Simplified QEMU command-line options can be passed with: | 
 |     nographic - disables video console | 
 |     serial - enables a serial console on /dev/ttyS0 | 
 |     kvm - enables KVM when running qemux86/qemux86-64 (VT-capable CPU required) | 
 |     kvm-vhost - enables KVM with vhost support when running qemux86/qemux86-64 (VT-capable CPU required) | 
 |     publicvnc - enable a VNC server open to all hosts | 
 |   qemuparams="xyz" - specify custom parameters to QEMU | 
 |   bootparams="xyz" - specify custom kernel parameters during boot | 
 |  | 
 | Examples: | 
 |   $MYNAME qemuarm | 
 |   $MYNAME qemux86-64 core-image-sato ext4 | 
 |   $MYNAME qemux86-64 wic-image-minimal wic |
