There was no v4.6-yakkety build for arm64, but v4.8 booted fine. I further bisected this down to:
0cb0786bac159 ARM64: PCI: Support ACPI-based PCI host controller Presumably nova in newer OpenStack releases has made changes to the libvirt xml it generates that requires additional kernel support. I'll attempt a backport of the necessary changes to get an idea of feasibility of repairing this w/ a kernel change. Can someone provide a copy of a guest XML generated by an earlier OpenStack that does successfully boot xenial guests? An alternative approach we could investigate if the kernel backport proves infeasible would be to see if we could go back to the older XML format until xenial guest support EOLs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1797092 Title: xenial guest on arm64 drops to busybux under openstack bionic-rocky Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Bug description: on openstack rocky-bionic (with patch, see 1771662), xenial guests will fail to launch as they drop to the busybox prompt after booting. However, bionic guests will build and launch successfully.
