Yeah, finally we don't need to meet something like this everyday: "This SF.net email is sponsored by: Microsoft Defy all challenges.

I propose moving the kvm lists to vger.kernel.org, for the following benefits: - better spam control - faster service (I see significant lag with the sourceforge lists) - no ads appended to the end of each email If no objections are raised, and if the vger postmasters agree, I will mass subscribe the current subscribers so that there will be no service interruption. Opinions? -- error compiling committee.c: too many arguments to function |

Hi, Finally got the latest KVM sources to build and boot here. Now playing with the networking again, but I am getting the same problem with the e1000 driver that I had with the early drivers. Anyone have ideas how to approach this one: Intel(R) PRO/1000 Network Driver - version 7.2.7-k2-NAPI Copyright (c) 1999-2006 Intel Corporation. register_intr: No IOSAPIC for GSI 28 ACPI: PCI Interrupt 0000:00:03.0[A]: failed to register GSI ..... and then no Ethernet device available.

(Since the IA64 guys have already implemented BE guests on LE hosts, they should be aware of this discussion too, which is why I've CCed them.) After a short but torturous whiteboard session, followed by a much longer but less painful discussion, I'm fine with the virtio device config space being BE for PowerPC and LE for x86. In the future, we can use a feature bit to indicate that PCI config space contains an explicit endianness flag. (This will be set to BE or LE, *not* to "opposite of normal", because "normal" is also too vague.) -- Hollis Blanchard IBM Linux Technology Center |

By the way Marcelo, it would be polite to provide these stubs yourself to
avoid breaking the build on other architectures.
It looks like IA64 is still broken because of this.
