Yet another hypervisor detection tool for UNIX-like systems.
- Single high level language (Ada 2005). Even if certain things require more code.
- No root privileges required, ever. Even if it means running checks in inconvenient ways.
- Support for at least the most popular UNIX-like systems, not just Linux.
To build it, you need GNU Make, GNAT 4.x or higher (Ada 2005 support required) and gprbuild.
Build setup is rather simplistic at this time.
cd hvinfo gmake gmake install PREFIX=<some dir>
Building a Debian package
Debian packaging is not yet good enough to get it included in Debian, but should be fine for local use. Install the devscripts package and do:
debuild -us -uc
If you have your Ada toolchain installed in an unusual location, it's better to ensure you have it in your $PATH.
OS and hypervisor support
CPUID-based checks that can detect KVM, Xen HVM, VMware, bhyve, and Hyper-V are supported on any OS.
Xen PV vs. Xen HVM check is supported on Linux and FreeBSD.
The easiest way to detect VirtualBox, Parallels, and some other hypervisors that don't use CPUID identification is to check the SMBIOS vendor name, and this is currently only supported on Linux because it provides DMI information via sysfs to unprivileged users. FreeBSD requires root privileges for DMI reading, so Parallels is undetectable on FreeBSD right now.
Container systems such as LXC and OpenVZ are not supported yet.
Virtualization systems for platforms other than x86 aren't supported either.
Patches are welcome.
- Implementation-independent makefile (anyone knows how to make ifdef work in both make flavours?)
- Containers virtualization detection.
