Can I install OLVM on top of Oracle Linux 7 Update 7 or is it required to stay with Oracle Linux 7 update 6?
I am confused because Install Guide is talking about OL7U6, but then again the OL7_Latest Repo seems to be required to be enabled.
Can I use the latest UEK5 Kernel for both OLVM (Manager) and KVM Compute Host?
Can somebody clarify?
Yes, it's 7.6 or higher, not "7.6 exactly". The latest kernel from official yum repository or ULN is also supported.
Oracle software never requires the exact patchset level, but only the minimal one - otherwise this could open you to security vulnerabilities that only patched in the "latest" channel.
