I want to replace Windows Server 2012 R2 and Hyper-V on my homeserver with CentOS and KVM. My plan is to virtualize one Windows 8.1 machine and several smaller Linux machines like on Hyper-V, there is no need to migrate, I'll start from scratch. I also want to use PCIe Passthrough to pass my Tevii S471 to a guest, and yes my CPU and MB support VT-d (Xeon 1245v3 on a Gigabyte GA-Z87X-UD5H).
Should I use CentOS 7? Also I probably have to switch to the latest stable Kernel to provide compatibility for PCIe passthrough am I right?
I don't know which interface to use, because for simple tasks I want to use a webif. What about oVirt? Or is there anything better for my purposes? I already virtualized with KVM under Arch Linux on the same board and CPU with libvirt and VMM, but VMM is a PITA to use and it creates pretty outdated templates.
