NB: Since Gal got assigned bz 1678290, I've reassigned this and bz 1677105 to him in order to keep the 3 bugs "together" (similarly altered the priority as well).
Change the priority to high since it's a normal use case and easy to reproduce. Related comment from Markus here: https://bugzilla.redhat.com/show_bug.cgi?id=1678290#c9
In bug 1678290 (from where this is cloned) the component is virtio-win, while here it's qemu-kvm-rhev. I'm not sure if this is intentional or a leftover from the clone... Also there, the problem can't be reproduced with libvirt, so this should not be affecting customers, therefore priority=medium. See https://bugzilla.redhat.com/show_bug.cgi?id=1678290#c33 for details.

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
