I’ve got a question which maybe actually be Xen specific, rather than Qubes, but hoping some of you could give useful pointers. I’d like to try out some unikernel and try it out on my Qubes machine (similarly to what mirage firewall is doing). I have the dummy no-op kernel built based on rusty hermit. It uses rusty-loader. So I have both the compiled unikernel and the loader. I can’t find a way to create a qube with those. I mean, I know how to specify the kernel via props when creating a qube, but I can’t seem to find the way to specify which loader to use.
Some quick search showed that in bare Xen this looks doable, because the guest config file has bootloader section (xm create). Does anybody have experience running non-linux,win guests under qubes?
