While building Openstack Lab, I happened to encounter an error message, just like I saw in the log file. tail -f /var/log/nova/nova-compute.log

This error occurred when trying to start an instance created earlier.
nova start 0b79cc65-c530-4e55-99b8-157524033d14
Obviously, I encountered some problems when manually starting the kvm machine, so I used the /etc/libvirt/qemu.conf file
user="qemu"
group="qemu"
dynamic_ownership =0
To prevent this error, please revert the changes to:
systemctl stop libvirtd
Edit the qemu.conf file:
sudo vim /etc/libvirt/qemu.conf
Set the following
user="nova"
group="nova"
dynamic_ownership =1
Save the file and restart the libvirt daemon
systemctl restart libvirtd
You should now be able to launch Openstack Instance on the compute node.
