Michal, you made the fix for bug 1461270 in 7.5, can you check whether this is
a duplicate of that one?

Yes, this is a duplicate. I've found this error message in the logs:

Aug 23 12:44:44 cpt0-dpdk-totp libvirtd[3077]: 2018-08-23 10:44:44.275+0000: 3091: error : virCommandWait:2601 : internal error: Child process (ovs-vsctl --timeout=5 get Interface vhu4b16b469-82 statistics:tx_errors) unexpected exit status 1: ovs-vsctl: no key "tx_errors" in Interface record "vhu4b16b469-82" column statistics

Upgrading to libvirt-3.4.0 or newer will solve the issue. I'm closing this one.

Yes, missing vhostuser interface names are solved by that bug.
