We currently run about 300 VMs with oVirt, both Linux and Windows servers. Cloud init works great for Linux VMs and we would like to do the same for Windows. We have a 2012r2 sysprep template but we do not manage to configure the initial run such that the new Windows VM boot *and join our AD domain* thereafter. Does someone have any clues/informations about this kind of operation ? How to specify unattend file in the 'New Virtual Machine' ? What kind of data (and format) is required in the 'sysprep' field ?

Best whishes to everyone!

Denis

PS: We run oVirt Engine 4.0.5
