[Xen-users] Re: [Xen-devel] PVOPS dom0 requires nomodeset to boot but video requires modesetting driver

["John McDermott (U.S. Navy Employee)" <john.mcdermott@xxxxxxxxxxxx>]

Konrad,

We are focused on developing a secure version of the hypervisor, by removing 
and refactoring code instead of adding security features. We don't have much 
kernel expertise, so we just fiddle 'till we get a fairly current kernel that 
works for our development environments. However, we are set up to capture full 
debug info all the time, so if we get an interesting kernel manifestation, can 
we report it. In this case, I have schedule pressure, so I am going to 
re-organize the particular DQ35JO to be just a plain Fedora box. However, I 
will be trying all over again with a different box, to set up a new development 
environment with the latest pvops dom0. I will make sure we have drm.debug=255 
on all of our development systems, but I don't know what the i915 option is.

We are also doing some fuzz testing of the hypervisor, so if we get anything 
interesting related to pvops, we'll post.

I will follow up to let you know how near to the present we are able to get, 
with pvops dom0 versions, on my next attempt.

Sincerely,

John

@Konrad, they just would not build. Usually at make modules, but not always, 
sometimes they died in modprobe.
