So I suggest to report this error to the libvirt community,
https://libvirt.org/bugs.html with the above logs, and the libvirt /
qemu logs attached.

Title:
Failed to attach second NIC on 1 vcpu ubuntu guests with qemu-kvm
5.1.0
Status in OpenStack Compute (nova):
Invalid
Bug description:
Description
===========
Centos 8.3 Host - failed to attach second NIC on 1 vcpu ubuntu guests with
qemu-kvm-5.1.0-14.el8.1.x86_64
Downgrading to qemu-kvm-4.2.0-29.el8.3.x86_64 fixes the problem.
First seen in Octavia:
http://lists.openstack.org/pipermail/openstack-discuss/2021-February/020218.html
https://storyboard.openstack.org/#!/story/2008651
Steps to reproduce
==================
Kayobe (kolla-ansible under the hood) deployed all-in-one on baremetal:
https://docs.openstack.org/kayobe/latest/contributor/automated.html#overcloud
ubuntu images -
https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img
Problem reproduced on bionic, focal, groovy and hirsute.
Failing flavor - 1 VCPU - 16G RAM
Working flavor - 2 VCPUs - 1G RAM
openstack server create --flavor 16g --image focal --config-drive True
--key-name test --network demo-net testvm16g
openstack --debug server add port testvm16g testvm1port
Expected result
===============
Proper attachment of NIC to VM
Actual result
=============
novaclient.exceptions.ClientException: Unknown Error (HTTP 504)
clean_up AddPort: Unknown Error (HTTP 504)
Environment
===========
1. Openstack Ussuri
openstack-nova-compute-21.1.2-1.el8.noarch
openstack-nova-common-21.1.2-1.el8.noarch
2. Which hypervisor did you use?
Centos 8.3 - Libvirt + KVM
2. Which storage type did you use?
SSD with ext4
3. Which networking type did you use?
Tested on Neutron with OpenVSwitch, and Neutron with OVN
