Not sure if it is a virtio-win bug?


wyu,

Please update your results if I missed important information. Many thanks.

Ran with ws2012r2
Still hit this issue with virtio-win-prewhql-158 with q35.
cannot hit this issue with pc chipset with both virtio-win-prewhql-158 and virtio-win-prewhql-172


Thanks
Yu Wang

Can reproduce this issue with win8.1-64 and q35 machine type.

How reproducible:
3/5

pkg:
virtio-win-prewhql-172
qemu-kvm-4.1.0-14.module+el8.1.0+4548+ed1300f4

Steps:
1) boot up guest with a new data disk(virtio-blk-pci).
2) format this disk.
3) hotuplug this data disk.

After step3,
1) can get response from qmp.
{"execute":"device_del","arguments":{"id":"data-disk"}}
{"return": {}}
{"timestamp": {"seconds": 1573101016, "microseconds": 723609}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/data-disk/virtio-backend"}}
{"timestamp": {"seconds": 1573101016, "microseconds": 777354}, "event": "DEVICE_DELETED", "data": {"device": "data-disk", "path": "/machine/peripheral/data-disk"}}

2) The disk status is changed to "Unknown" and can not operate it.
wmic diskdrive get index (can't get disk index 1)

Virtio-scsi also has the same issue.

Hotplug then unplug:

Sorry for https://bugzilla.redhat.com/show_bug.cgi?id=1752465#c15, please ignore it.

Hi vadim,

The bug will be closed automatically, I try to reproduce it  and hit the scenario in https://bugzilla.redhat.com/show_bug.cgi?id=1833187
So this problem seems to similar with Bug 1833187,  both are hot-plug/unplug problems.
I can track this issue with Bug 1833187 from my side. And I agree to close it if not plan to fixed this bug these days.
What's your opinion? Do you prefer to keep it or closed automatically.


Thanks

Hi Menghuan,
I have no problem with closing this bug, if we are going to keep https://bugzilla.redhat.com/show_bug.cgi?id=1833187
alive.
Best,
Vadim.
