At least the mysql case should be fixed in hobbit-plugins 20180610,
see https://bugs.debian.org/873838. The according changelog item:

  * Whitelist multipath-related /[aio] false positives for mysql/mariadb
    servers in libs check. Thanks to Daniel Rieken for the bug report!
    (Closes: #873838)

Don't know what causes libvirt-qemu case. If the fix for mysql
mentioned doesn't fix it for libvirt-qemu, too, the output of "lsof -p
<pid-of-libvirt-qemu-binary>" might give some hints.

  Kind regards, Axel (one of Debian's hobbit-plugins and xymon maintainers)
