I've backported the necessary fixes and verified that the result does solve the problem: https://git.launchpad.net/~dannf/ubuntu/+source/linux/+git/linux?h=xenial-arm64-acpi-pci
That being said, the changes are not particularly isolated, so it will require careful review and testing for regression risk. Particularly on any armhf platforms that support PCI (I don't have any).

However, bionic guests will build and launch successfully. Dann F believes this may be related to the xenial image not containing appropriate acpi modifications. xenial guest console log: https://pastebin.canonical.com/p/ntRxFJTvjV/ xenial virshxml: https://pastebin.canonical.com/p/cCY4ZVynP7/ bionic virshxml for comparison: https://pastebin.canonical.com/p/MSV3xG7t7g/ validation: https://pastebin.canonical.com/p/nC9pfSkXVs/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1797092/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
