My impression is that Simplify and promote using in-vm kernel · Issue #5212 · QubesOS/qubes-issues · GitHub will fix a lot of those issues, is that correct?

Why can’t Qubes just use grub.d? Why would it require another kernel?

Because Qubes uses at this time by Qubes default a kernel supplied by dom0 (host). Not kernel supplied by VM. VM grub.d / grub.cfg is ignored by default. This might change in future as per ticket Simplify and promote using in-vm kernel · Issue #5212 · QubesOS/qubes-issues · GitHub.

Can we trust that the changes on the default kernel option will land some time soon?
Is there an alternative solution to this, like running the whonix gw and ws as HVMs (maybe?) to provide the security mechanisms?

Hi all, is this topic up-to-date? I looked through what I could on Github. For instance, the first issue, it seems there is still some work to do, but hopefully recent developments will help resolve the issue. And it seems the workaround is to just write what you want to within a notepad and paste the contents into your browser (that ideally doesn’t have JS enabled).

Thanks for your time :slightly_smiling_face:
