Starting with Data Protector A.09.05 Red Hat Enterprise Linux 7.0 and 7.1 is now a supported Cell Manager platform.

If you ever worked with Hyper-V on Windows 2008 R2 you might know the Linux support is still an issue compared to other hypervisors like VMware. In the meantime Microsoft official supports SLES and RHEL as Hyper-V R2 guests. To have them running smoothly, you should install the Linux Integration Services Version 3.1 for Hyper-V …
