ROS Host + ROS guest (different versions)?

RouterOS Virtualization
1

Is it possible and how to run different versions of host and guest ROS?

If I make the RouterOS Image it makes it with the current running ROS but how can I make sure that it stays that version - i.e. would need a copy of initrd and kernel images.

yes, different versions are possible. If you created your RouterOS image using older KVM in RouterOS will automatically extract kernel and initrd and use them.

Also, creating an image and then downgrading it to older version (creating RouterOS 6.12 and then downgrading to 5.26) will work.

Thanks for the info, will try that.
