Hi,

I'm concerned about the impact on our test suite: it seems suboptimal
to (automatically) test code paths that are different from the ones
most users will go through. IIRC we're setting a kernel cmdline
parameter when running the test suite, so perhaps this changing of
defaults could be disabled when a testing environment is detected?
(Assuming the libvirt/qemu stack we're using is not affected by the
same issues as VirtualBox.)

Cheers,
