37Usage: qemu-run [OPTION]...
38Make a qemu image($flash_name) for OHOS, and run the image in qemu according
39to the options.

41    Options:
42
43    -f, --force                    rebuild ${flash_name}
44    -n, --net-enable               enable net
45    -l, --local-desktop            no VNC
46    -b, --bootargs boot_arguments  additional boot arguments(-bk1=v1,k2=v2...)
47    -g,  --gdb                     enable gdb for kernel
48    -h, --help                     print help info
49
50    By default, ${flash_name} will not be rebuilt if exists, and net will not
51    be enabled, gpu enabled and waiting for VNC connection at port 5920.
