Is Chrome OS based on Linux at Genymotion?
isnt chrome os linux though
Yes, Chrome OS is based on Linux, but Genymotion Desktop support is about the OS and environment you run it on, not just the kernel underneath.
Genymotion Desktop is supported on macOS and on Windows and Linux x86_64, and it is not supported inside virtual environments or servers. On Windows 10 it is no longer officially supported, and on Linux the recommended hypervisor is QEMU per the Linux help article, while Windows uses VirtualBox by default.

What are you trying to run it on, Chrome OS itself or a Linux VM?
