I have a virtual machine with Debian 13, can I install Genymotion there?

Last verified against genymotion.com:

No. Genymotion Desktop is not supported inside virtual machines, and Debian 13 is only supported on bare metal Linux x86_64. See the supported OS requirements in Get Started with Genymotion Desktop and the VM limitation in the same guide.

If you want, you can install Genymotion Desktop on a supported Debian 13 host instead of inside the VM.
