cherry a141ce0848 Rig the hypercall callback page such that when the kernel happens to 
run without a XEN domain loader having previously overwritten the
hypercall page with its hypercall trampoline machine code, we still
get to detect its presence by calling the xen_version hypercall stub.

We use this hack to detect the presence or absence of the hypervisor,
without relying on the MSR support on HVM domains.

This works as an added sanity check that the hypercall page
registration has indeed succeeded in HVM mode.

NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.

Building

You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:

./build.sh -U -u -j4 -m amd64 -O ~/obj release

Additional build information available in the BUILDING file.

Binaries

Testing

On a running NetBSD system:

cd /usr/tests; atf-run | atf-report

Troubleshooting

Latest sources

To fetch the main CVS repository:

cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P src

To work in the Git mirror, which is updated every few hours from CVS:

git clone https://github.com/NetBSD/src.git
