From your command line, looks like you're installing RHEL6.3 using a rhel-7.0.0 machine type. I don't think this is the cause of the bug, but for the sake of consistency, please run the test again using a RHEL6.5 guest with a 6.5 machine type (and/or RHEL7 guest with rhel7 machine type). Besides, what's the error you see on the guest when trying to reboot?

No hit this issue. Since running RHEL6.3 using a rhel-7.0.0 (the original environement where you've found this bug) should not be supported, I'm closing this bug. But in this last test you've changed two variables: install is now via PXE and you're now using 6.5 machine type to install RHEL 6.5, so maybe it's worth testing live-storage migration during installation via local file-system, but I'll leave this up to you. If you reproduce it again, please reopen the bug. Thanks.
