This bug is to make an urgent request to build a new RHV Guest tools ISO for RHV Windows guest with the fix from bz#1596457. Why is this important? Because bz#1596457 makes guests hang and fail live snapshot/merge operations as per bz#1572801 with 100% probability. P.S. Not sure I chose the right component, but I could not find anything closer to guest agent than releng. Please change, if needed.
Using rhv-guest-tools-iso-4.2-8.el7ev.noarch With RHEV-Tools 4.2.8 and QEMU guest agent 7.6.2 installed I get this: [root@hostname ~]# virsh qemu-agent-command widle '{"execute": "guest-fsfreeze-freeze"}' Please enter your authentication name: root Please enter your password: error: Guest agent is not responding: Guest agent not available for now when I'm running disk check through crystaldiskmark (or there is an updates check running) which is OK. I can execute fsfreeze-freeze normally otherwise (and fsfreeze-thaw).
Please re-test on 4.3 build
With RHEV-Tools 4.3.1 and QEMU guest agent 7.6.2 installed I get this: [root@slot-9 ~]# virsh qemu-agent-command AHOJ_W10 '{"execute": "guest-fsfreeze-freeze"}' error: Guest agent is not responding: Guest agent not available for now when I'm running disk check through crystaldiskmark (or there is an updates check running) which is OK. I can execute fsfreeze-freeze normally otherwise (and fsfreeze-thaw).
