I have just verified that the reproducer for Red Hat Enterprise Linux is
valid for Bionic:
1.Start a guest:
$ virsh start test1
2.Do 'virsh list' in a loop:
$ for i in {1..1000}; do virsh list; done
3.Open another terminal, do 'virsh domstats' in a loop:
$ for i in {1..1000}; do virsh domstats; done
4.Check the libvirtd.log:
$ cat /var/log/libvirt/libvirtd.log | grep -i "Hash operation not allowed
during"
