start fuchsia in qemu with a FVM disk
start fuchsia in qemu with a FVM disk usage: fx qemu [--no-build] [-z <zbi_image>] [RUN_ZIRCON_FLAGS] -z <zbi_image> use <zbi_image> instead of the default. --no-build do not attempt to build the fvm and the default zbi images. A custom zbi image passed by a '-z' flag is never built. This command delegates to //zircon/scripts/run-zircon. Other flags are documented in that script, and can be discovered by passing -h or --help.
