The test itself is a simple usage of SQLite. It is stock KVM as available in 2.6.31 on Ubuntu Karmic. So it would be the environment, not the test. So assuming that KVM upstream works as expected that would leave either 2.6.31 having an issue, or Ubuntu having an issue. Care to make an assertion on the KVM in 2.6.31? Leaving only Ubuntu's installation.
kvm has nothing to do with it, it's purely qemu. For a long time qemu has defaulted to write-through cacheing. This can be overridden and maybe that's what Ubuntu or Phoronix do.
Can some KVM developers attempt to confirm that a 'correctly' configured KVM will not demonstrate this behaviour? http://www.phoronix-test-suite.com/ (or is already available in newer distributions of Fedora, openSUSE and Ubuntu.
A correctly configured kvm will not demonstrate this behaviour. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
