Hi,

I just wanted to run xen hypervisor on ARMv8 architecture, I tried on
Hikey960 platform which has armv8, but latest xen giving cpu errors.

Could you please tell me, on which platforms latest xen is working?

Thanks,
Omkar B

If your platform supports virtualization. Then there are a good chance for Xen 
to boot on it out-of-box. So what platform are you looking at?

Regarding the hikey960, there are patches on the ML to fix boot. See [1].

Hi Julien,

Awesome, after applying those patches in latest xen, hikey960 able to
enable 4 CPUs and other four CPUs are giving error -5.
And after using "hmp-unsafe" in xen command line, all CPUs got enabled
successfully.

Thank you,
