Hi,

in the past I’ve seen this kind of weird issue/problem.

The workaround I’ve applied, without any kind of impact to existing VMs/Services, is:

# systemctl restart libvirtd 

on the kvm host with the “duplicate key” error.

Unfortunately I didn’t deep dive into any particular analysis.

Someone can give me some advice ?

Thanks.
