Hello,
I would like to set up a virtual GNU/Linux-Distribution for testing purposes.
I read that hardware virtualization doesn't play well with libreboot.
Can anyone give me some advice on how to set up a virtualized Trisquel instance?

I always used HW-virtualization, so I've got no idea which setup is good for SW-virtualization.

Thanks in advance
:)

You might be able to do it with 1 cpu/core for the VM, though there are reports that guest OS will crash with this setup.
With both cores, you'll get kernel panics on the host OS.

There may be a few T400 laptops with CPUs that work well with hardware virtualization, but they are rare.

Hardware virtualization is unstable without CPU microcode updates. Libreboot excludes these, since they are non-free.

You can use software-based virtualization, if you disable the KVM module in the linux kernel. Xen-based virtual machines should be fine, and offers decent performance.

Thank you for your fast answer :).
Do you know some good reading material on Xen-Based virtual machines.
I never used it before.

Thanks in advance.
