Ops little mistake. Version-Release number of selected component (if applicable): OSP13 z3 I meant, OSP13 z1 It's a valid issue a patch has been sent upstream but still need some work https://review.openstack.org/#/c/595592/ (In reply to Sahid Ferdjaoui from comment #3) > It's a valid issue a patch has been sent upstream but still need some work > > https://review.openstack.org/#/c/595592/ Tested upstream patch and it works as expected. The rx_queue_size queue size is not enforced anymore on SR-IOV devices. Test done using both SR-IOV VF (aka neutron port type direct) and SR-IOV PF (aka neutron port type direct-physical) Thanks! *** Bug 1635568 has been marked as a duplicate of this bug. *** Updating Target Milestone to z3 for all Modified medium bugs Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

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:
