As Kev wrote, we’re exploring rump kernels which are related, but I think it’s more a question whether the unikernel supports seL4 and not the other way around.

seL4 is certainly powerful and general enough to run any such configuration, but the unikernel might be making assumptions about the hypervisor layer, i.e. it might expect a specific one.

or hardware without an intervening OS such as Linux or Windows.

Will seL4 support any unikernel, such as Drawbridge or MirageOS, in the
