+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
+ $MYNAME path/to/bzImage-qemux86.bin path/to/nfsrootdir/ serial
+ $MYNAME qemux86 iso/hddimg/vmdk/qcow2/vdi/ramfs/cpio.gz...
+ $MYNAME qemux86 qemuparams="-m 256"
+ $MYNAME qemux86 bootparams="psplash=false"
+ $MYNAME path/to/<image>-<machine>.vmdk
+ $MYNAME path/to/<image>-<machine>.wic
