Dear all, Because of our puppet integration at work, it would like to know if there is a way in ovirt to know, from WITHIN a virtual machine, the hypervisor on wich the vm is running?

Kind regards, Koen _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi, yeah of course, there are various scripts for that i. e. http://www.dmo.ca/blog/detecting-virtualization-on-linux/ (google is your friend) the (afaik) fastest way to detect ovirt is: dmidecode | grep oVirt but this needs root privileges.

And unfortunately, you can even tell the UUID of the specific host on top of which the VM was first started via dmidecode -s system-serial-number in the guest. This feature is unfortunate, as it cannot really be trusted (it does not update upon migration), and breaks an important abstraction.

I'll dig into which infos are furthermore provided when I get some time..
