hi all,
hoping someone could shed some light on this issue I’ve worked on several days.
I have installed openstack through devstack and it works well when I create an
instance.
stack@ubuntu:/var/run$ openstack server list
+--------------------------------------+-------+--------+--------------------------------+--------------------------+---------+
| ID | Name | Status | Networks

2001:db8::3 | cirros-0.3.5-x86_64-disk | m1.tiny |
+--------------------------------------+-------+--------+--------------------------------+--------------------------+---------+
The default version of libvirt is 2.5.0 while I want to use libvirt 3.4.0. What
I have done is to install libvirt 3.4.0 manully since no apt repo has such
version of libvirt.
To check libvirt version,
virsh # version
Compiled against library: libvirt 3.4.0
Using library: libvirt 3.4.0
Using API: QEMU 3.4.0
Running hypervisor: QEMU 2.9.0
However, my openstack seems to lose connetion with the new version of libvirt.
It shows error when I create a new instance.

The log shows

What can I do to let openstack connect to the new libvirt?
thanks!!
