Description Gu Nini 2017-11-16 07:56:39 UTC
Description of problem:
When input characters '|' and '<' in RHEL7.4/7.5 guests, the output are both '>'; while input characters '<' and '>' in RHEL7.4/7.5 guests, the output are both '|'.

Version-Release number of selected component (if applicable):
Host kernel: 3.10.0-765.el7.x86_64
Guest kernel: 3.10.0-766.el7.x86_64(7.5)  3.10.0-693.el7.x86_64(7.4)
Qemu: qemu-kvm-rhev-2.10.0-6.el7

How reproducible:

Steps to Reproduce:
1. Start a RHEL7.4/7.5/Win2016 guest.
2. After the linux guest boots up, try to input characters '|' and '<'.
3. After the windows guest boots up, try to input characters '<' and '>'.

Actual results:
In step 2, the outputs are both '>'.
In step 3, the outputs are both '|'.

Expected results:
The outputs are the correct ones.

Comment 2 Gu Nini 2017-11-16 08:30:08 UTC
Please note the bug only occurs when connect the guest through vnc, while no the issue when connect it through spice.

Comment 3 Gu Nini 2017-11-24 08:02:49 UTC
No the bug problem on rhel7.4z qemu version qemu-kvm-rhev-2.9.0-16.el7_4.12.x86_64, so set the bug as regression.

Comment 5 Gu Nini 2017-11-27 04:36:35 UTC
In grub of the linux guest, '<' and '>' are recognized as '|' just like that for windows guest.

Comment 6 Guo, Zhiyi 2017-12-14 16:01:25 UTC
Seems this issue is introduced by Bug 1503128 - update reverse keymaps for qemu vnc server.
Test against qemu-kvm-rhev-2.10.0-4.el7.x86_64,no such issue happen.
Test against qemu-kvm-rhev-2.10.0-5.el7.x86_64, issue happens.

Test against qemu-img-rhev-2.10.0-11.el7.x86_64 from my part, issue only can be reproduced by vncviewer and cannot be reproduced with remote-viewer

Fix included in qemu-kvm-rhev-2.10.0-19.el7

Comment 12 Guo, Zhiyi 2018-02-05 08:51:26 UTC
Test against qemu-kvm-rhev-2.10.0-19.el7.x86_64

Client used:
vncviewer and remote-viewer

1.Boot guest with qemu cli:
/usr/libexec/qemu-kvm -name input-test -m 4G \
-cpu EPYC,enforce \
-smp 2 \
-netdev tap,id=idinWyYp,vhost=on -device e1000,mac=42:ce:a9:d2:4d:d7,id=idlbq7eA,netdev=idinWyYp \
-uuid 215e11b2-a869-41b5-91cd-6a32a907be7e \
-device ich9-usb-uhci6 \
-drive file=/home/nfs/latest75.qcow2,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=stop
  -device ide-drive,drive=drive-scsi-disk0 \
-qmp unix:/tmp/input-port,server,nowait \
-monitor stdio \
-vnc :0 \
-S \
-serial unix:/tmp/console,server,nowait \
2. Connect desktop via vncviewer/remote-viewer, open a text editor and input | < >

On rhel7.5 guest, characters displayed in text editor is same as the input
Test result against windows 2016 guest is same as rhel7.5 guest
