After upgrading foreman to 2.4.0 we can no longer create hosts using libvirt compute resource. When creating the host the VM is created on libvirt side (with the correct UUID) but for some reason the UUID stored for the vm on foreman side is wrong it adds “8_” in front of the UUID.
This generates an error since foreman is not able to start the VM cause it cannot find it with the incorrect UUID on libvirt.

Part of the log:
