Hello, A bit confused with "free Linux/Ubuntu VMs". Do you mean you looking for VM image ( to directly run your tests ) or an emulator to create VMs locally and play around. For the first, I have not tried with. Probably vmware images can be found at : http://www.osboxes.org/vmware-images/ But, if you are looking for emulators, I would say Xen and Virtualbox. I use them for most of my development for linux kernel related work items. To start with, I would suggest you to start with Virtualbox. Its easy to begin w.r.t. configuration, installation and other items. Link : https://www.virtualbox.org/ Regards, ~Praveen. On 14 March 2017 at 15:45, François <fser@code-libre.org> wrote:

Well, I am using QEMU system emulator, for it's easier to connect to GDB debugging and itself handles bootloader thing. You can set all things up by one line parameters, really tidy.
The disadvantage is that I've been told system running in QEMU is slow, but for kernel programming that wouldn't be the problem, will it?
What about others?
Depending on what you're working on, you can also use User Mode Linux (UML) [1] which produces a elf, that you can run easily on top of your existing linux distro. Basically, you have to choose the "um" arch when compiling your kernel.
