Hi,
I'm not sure, but might this even be an security issue?
I don't think it's serious, it can easily be changed via a hook, there's also an RFE somehwere in queue for this to be configurable directly in UI (not much work, 3.5 perhaps) and since inside the guest you are not aware of migrations you can't really "trust" that value anyway
at least you could get an idea of the underlying infrastructure.
well, yes. But in addition in /etc/vdsm/vdsm.id you can define your very own host UUID but by default yes, after enough runs…. Thanks, michal
I'll dig into which infos are furthermore provided when I get some time..

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.

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?
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.
