Different OSes have different capabilities and behaviors sometimes. We have to distinguish them then.
For example, our clients want to send NMI interrupts to certain guests(eg.Linux distributions), but not others(eg.Windows guests). They want to acquire the list below: guest1: RHEL 7 guest2: RHEL 7 guest3: Ubuntu 12 guest4: Ubuntu 13 guest5: Windows 7 ......
AFAIK, neither libvirt nor openstack, nor qemu, have such capbility of showing these guest OS infos. Libvirt now supports to show host capabilities and driver capability, but not an individual guest OS's capibility. We may refer to http://libvirt.org/formatdomaincaps.html for more information.
Hello. I wrote a utility a few years ago to detect which OS is running in each qemu VM under libvirt via memory probing. I have not touched the code in a few years. YMMV. http://pastebin.com/m0mfcK8G
