I have two kernels installed 5.7 and 5.8, and I have a laptop without any virtualization technology supported (dual cores old cpus), so the only way to use virtualbox is to use the 6.0 version which is no more supported after July/2020.
With kernel 5.8 virtualbox 6.0 cannot be used due to lack of support and give an error while building module or launching, but with 5.7 it works perfectly.
error: ‘cpu_tlbstate’ undeclared (first use in this function); did you mean ‘cpuhp_state’?
What I want to do is boot my machine with 5.8 but when building/launching virtualbox to use 5.7 kernel modules ? Is it possible with Manjaro/Linux ?
