>From Manoj: The way we use Ubuntu distributions is that we download ISO images and then create separate hard disks for each Ubuntu version. If you test with just changing the kernel version matching a specific Ubuntu version but all others components of the OS including libvirt, qemu are unchanged, I'm not sure we have the same environment. Based on the difference in behavior we observed across 3 Ubuntu versions, we suspected that the introduction of vfio in 14.04 or the Qemu version in 14.04 could be the culprit.
pcimem is a user-space utility to peek/poke BAR registers of any PCI device. It does not require the LiquidIO driver. The steps you followed to use pcimem looks correct. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563375 Title: A a single PCI read or write appears twice on the PCIe bus.
