We now have a working solution for producing regular .vhd images as part of our release process: CBS is now using qemu-img-ev and qemu-kvm-ev from the Virt SIG, instead of the versions in CentOS Linux base. We don't need either VirtualBox or changes in Image Factory. If anyone has access to Hyper-V on Windows and would be willing to test two Vagrant images, please let me know. I received conflicting test results from Thomas and Michael, and I'd like to have at least an additional test before deciding whether to release them or not. Thanks, Laurențiu
