Upgrading Oracle VM Manager Release 3.4.5 to 3.4.6 fails on an Oracle Linux guest virtual machine when the guest OS is first upgraded to Oracle Linux 7 Update 6. Similarly, installing Oracle VM Release 3.4.6 on guest virtual machines running Oracle Linux 7 Update 6 is failing.
Workaround: Upgrade the guest OS to Oracle Linux 7 Update 6 after Oracle VM Manager Release 3.4.6 is running on the virtual machine.
