<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN">Hello Folks,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN">Thanks to Chris Friesen for point this out, but we believe the issues you are experiencing is due to the requirement for guests to be backed by huge pages to operate with OVS-DPDK vhost-user
based ports/interfaces. The master (default) behavior for the latest nova will default to 4K pages for the guest, but this is not compatible with OVS-DPDK. The guests must be configured to use a
<i>flavor</i> that has the property <i>hw:mem_page_size=large</i> set.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN">You can follow this link to read more about the requirements on the guests for OVS-DPDK:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:ZH-CN"><a href="https://docs.openstack.org/neutron/rocky/admin/config-ovs-dpdk.html"><span lang="EN-CA">https://docs.openstack.org/neutron/rocky/admin/config-ovs-dpdk.html</span></a></span><span lang="EN-CA" style="mso-fareast-language:ZH-CN"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:ZH-CN">“vhost-user requires file descriptor-backed shared memory. Currently, the only way to request this is by requesting large pages. This is why instances spawned on hosts with OVS-DPDK
must request large pages”.<o:p></o:p></span></p>
