Re: [Minios-devel] Some queries regarding Unikraft on x86/arm



Hi Ajay,

Yes, that’s right. Currently, for arm32-unikraft, we plan to support Xen and Linux/KVM.

Both of them need hardware virtualization enabled processors.

 

> b) Unikraft (for x86) also uses HVM mode, and works _only_ with processors that have hardware-virtualization enabled, right?

Unikraft-x86 of KVM platform uses HVM mode, it should require hardware virtualization

enabled processors. But it seems the Unikraft-x86 of Xen platform is using PV-mode.

I am not sure about it, but I think Simon could give you a clear answer.

Subject: [Minios-devel] Some queries regarding Unikraft on x86/arm

 

Hi All.

It's pretty clear that PV-guests on ARM are not the way to go (neither there are any plans for support of PV-guests on ARM), primarily because of the following reasons :

       * Too much complexity in OS code while booting up, and in general.

       * Security issues (Meltdown).

So, rumprun, as of now is unusable for ARM, because rumprun is built with PV-guests in mind.

So, that leaves us with Unikraft.
So, kindly confirm :

 

a)

Unikraft (for arm32) is built using HVM mode, and will _only_ work with processors that have hardware-virtualization enabled, right?

b)

Unikraft (for x86) also uses HVM mode, and works _only_ with processors that have hardware-virtualization enabled, right?

Or Unikraft works/can-work using PV mode?



I think with the above two resolutions, we can be sure to zero-in on Unikraft for running unikernels.

Many thanks to everyone who have helped, big thanks to Julien (<julien.grall@xxxxxxx>) !!


 

Thanks and Regards,
Ajay
