Hi,
I'm going to create some virtual exam environment and maybe kvm/qemu/virsh can do the job.
This environment should consists several virtual machines (linux + windows) and several virtual networks. This is not a big deal. But after the baseline is created, I would like to simulate problems which must be solved by the examinees.
My idea is to use snapshots for this, so I can create faulty snapshots and assign them to in a combination with some good snapshots creating 'scenarios'.
Do you think it can be a working approach? Is there any better 'tool'/environment for this? Is there any guide for such thing?
Thanks L:

Thanks L:
for Linux RHEL based distros. I will suggest trouble-maker [1]
please have a look .... may be that can help

I've used it for my RHCE preparation ... it works like anything
Good Luck
Warm Regards
Thank you. My case is a bit more complicated. It consists of several different machines with different operating systems and different software running on top of it. Also I have to include a few Virtual Appliances as well, so what I really need is to create fully configured purpose-built virtual environments quickly but having no separate VM-s for different scenarios.

You need hardware virtualization support, and for ease of use, you can store the VMs in files. Xen might work as well, though I would suggest that you check whether there are particular requirements and choose the software that meets them best.
Depending on what you're trying to find out, using VMs may be the wrong way to begin with.

VMware have some rather nice "lab" software that lets you recreate groups of virtual machines instantly. I think it's designed for creating repeatable test environments. The name of this escapes me (and internet searches) right now, but I've often thought we could do with something similarly easy to use.
Another thing to look at would be the various orchestration tools, such as The Foreman, Heat and others.

I don't know if they can be used with KVM standalone however.
