** Description changed: + [Impact] + + * Libvirt has had the assumption that every VF (virtual function) will + have a PF (physical function) assigned, but that does not hold true on + some special Hardware like the Cavium ThunderX + + * Dannf helped some patches initially from Linaro to be accepted upstream + and those we'd want to backport to Bionic and Cosmic + + [Test Case] + + * Use VF passthrough to a KVM guest on Cavium thunderX + + * This needs plenty of setup and special HW, but Jason Hobbs & Dannf are + willing to do the verification in our test lab. + + [Regression Potential] + + * Review hasn't spotted any issues, but in theory there could be negative + effects to PF/VF pass-through cases. There is some code cleanup + associated that should not, but might cause issues on that. + I'd ask Jason to also run PF/VF workload on the PPA/SRU with other + Hardware as well (like our x86 test environment) to be sure of that + being ok. + + [Other Info] + + * n/a + + --- + After deploying openstack on arm64 using bionic and queens, no hypervisors show upon. On my compute nodes, I have an error like: 2018-05-16 19:23:08.165 282170 ERROR nova.compute.manager libvirtError: Node device not found: no node device with matching name 'net_enP2p1s0f1_40_8d_5c_ba_b8_d2' In my /var/log/nova/nova-compute.log I'm not sure why this is happening - I don't use enP2p1s0f1 for anything. There are a lot of interesting messages about that interface in syslog: http://paste.ubuntu.com/p/8WT8NqCbCf/ Here is my bundle: http://paste.ubuntu.com/p/fWWs6r8Nr5/ The same bundle works fine for xenial-queens, with the source changed to the cloud-archive, and using stable charms rather than -next. I hit this same issue on bionic queens using either stable or next charms. This thread has some related info, I think: https://www.spinics.net/linux/fedora/libvir/msg160975.html This is with juju 2.4 beta 2.
