The log message isn't necessarily indication for a bug.
OVMF is huge, so it pushes up total memory consumption of the guest. It
is normal that you see that message when using OVMF during boot time.
What is unclear to me is why your guest keeps trying to ask for more
pages after it boots up. Is your guest trying to balloon in pages? Do
you see the same message repeated when using seabios?
