commit 622ebf2fab0a9bf75ee12437bef28f60e083f849 Author: Moshe Levi <[email protected]> Date: Thu Aug 23 14:25:04 2018 +0300 libvirt: skip setting rx/tx queue sizes for not virto interfaces It seem that if driver name is None nova try to set rx_queue_size tx_queue_size config. (they define the virtio-net rx/tx queue sizes). Direct/Physical Direct vnic_types are not vritio so this kind of config is invalid and causing booting guest to failed. To avoid issues we skip such configuration these vnic_types Closes-Bug: #1789074 Change-Id: I45532896690ad9505f2b09c98d8d86b61bcfef2b ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1789074 Title: failed to boot guest with vnic_type direct when rx_queue_size and tx_queue_size are set Status in OpenStack Compute (nova): Fix Released Status in OpenStack Compute (nova) rocky series: New Bug description: Description of problem: Nova compute forces the virtio RX/TX Queue Size also on SRIOV devices. This makes VM spawn to fail. The configurable RX/TX Queue Size code is similar all the way from OSP10 to OSP13, so it's possible the issue is present also on other releases. Version-Release number of selected component (if applicable): OSP13 z3 How reproducible: (quick and dirty way) Change nova config file # crudini --set /var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf libvirt rx_queue_size 1024 # crudini --set /var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf libvirt tx_queue_size 1024 # restart nova_compute container docker restart nova_compute # boot a VM with an SRIOV (PF or VF) interface Actual results: Nova add on the sriov port section rx_queue_size <interface type="hostdev" managed="yes"> <mac address="fa:16:3e:9d:f0:52"/> <driver name="vhost" rx_queue_size="1024"/> <source> <address type="pci" domain="0x0000" bus="0x01" slot="0x14" function="0x7"/> </source> <vlan> <tag id="435"/> </vlan> Expected results: <interface type='hostdev' managed='yes'> <mac address='fa:16:3e:83:b2:84'/> <driver name='vfio'/> <source> <address type='pci' domain='0x0000' bus='0x01' slot='0x14' function='0x7'/> </source> <vlan> <tag id='435'/> </vlan> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </interface> Additional info: To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1789074/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
