arm_now is an easy way to instantly setup and start a virtual machine, a lot of CPU architectures are supported.
I mainly use this for security purpose (reverse/exploit).
$ pip3 install https://github.com/nongiach/arm_now/archive/master.zip
$ mkdir test
$ cd test
$ arm_now start armv5-eabi --clean
Welcome to Buildroot
buildroot login: root
# uname -m
armv7l
$ arm_now start microblazeel --clean
Welcome to Buildroot
buildroot login: root
# uname -m
microblaze
This might not work if there are a lot of files in the current directory. Use the --sync option, you have to type the command save before exiting the guest.
$ ls
a_file_created_on_the_host
$ arm_now start armv5-eabi --clean --sync
Welcome to Buildroot
buildroot login: root
# ls
a_file_created_on_the_host
# touch a_file_create_on_the_guest
# ls
a_file_created_on_the_host a_file_create_on_the_guest
# save
# poweroff
( back to host, you can also ctrl+] to kill qemu )
$ ls
a_file_created_on_the_host a_file_create_on_the_guest

// TODO: add boot time to this array.
- a fully working package manager (I will add it this weekend, come back next week!) // https://github.com/Entware/Entware-ng
- briged network
Press "Ctrl + ]" (Ctrl + altgr + ] on azerty).
It's based on buildroot, we download them from https://toolchains.bootlin.com/downloads/releases/toolchains/
Yes, it's a real virtual machine we use qemu-system-*. It's not a container or something based on chroot.
I do this project as a hobby, if you find bugs report and I will fix, the code source is very small about 300 lines of python, don't be afraid to pull request.
- A lot of cpu arch are still not supported, bfin, sparc, xtensa .., at line 28 of arm_now.py you will find a dict that you can play with to add new cpu arch.
- setup network interfaces
- add package manager (my next priority). opkg with https://wiki.openwrt.org/about/mirrors or http://pkg.entware.net/binaries/
- full support of cpio rootfs
- make a script based on buildroot that will compile every existing arch ? this sounds like hours of work :/
- let the user choose the libc, (musl, glibc, uclibc)
- allow the user to give any binary as input and start it in the right cpu arch, all dependencies should be automatically resolved and installed
- add windows host support (checkout "old" branch)
linux kernel, gcc, busybox, qemu, https://buildroot.org, https://toolchains.bootlin.com ...
