Comment 3 lijin 2018-07-17 04:33:21 UTC 
Can not reproduce with rhel7.5 version(qemu-kvm-rhev-2.10.0-21.el7.x86_64.rpm)

So it's a regression bug.

Comment 17 Ademar Reis 2020-02-05 22:48:32 UTC 
QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
