RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description xiagao 2016-12-08 02:47:45 UTC 
Description of problem:
Error describtion is not clear when executing guest-sync-delimited command without id parameter

Version-Release number of selected component (if applicable):
host:
qemu-kvm-rhev-2.6.0-27.el7.x86_64

guest:
win2012-r2
virtio-win-1.9.0-3.el7.src.rpm
qemu guest agent 7.3.2-1


How reproducible:
100%

Steps to Reproduce:
1.Boot guest with virtio serial and install/start guest agent.
/usr/libexec/qemu-kvm -S -name avocado-vt-vm1 -nodefaults -vga std -m 3G -smp 4 -drive file=50fee0e6-9b31-4dd0-bd33-6ce8e0a3ef77,if=none,id=drive-ide0-0-0,format=raw,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=0 -vnc :8 -rtc base=localtime,clock=host,driftfix=slew -boot order=cd,menu=on -enable-kvm -monitor stdio -qmp tcp:0:1238,server,nowait -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x7 -chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 -device virtserialport,bus=virtio-serial0.0,chardev=qga0,name=org.qemu.guest_agent.0 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:01:56,bus=pci.0,addr=0x3 -drive file=/usr/share/virtio-win/virtio-win-1.9.0.iso,if=none,readonly=on,media=cdrom,format=raw,id=cdrom2 -device ide-drive,drive=cdrom2,bus=ide.1,unit=0,id=ide-cd2

2. Connect the chardev socket in host side for sending commands to guest:
# nc -U /tmp/qga.sock

3. Send  "guest-ping" command in the host side:
{"execute":"guest-ping"}
{"return": {}}


4. Send "guest-sync-delimited" command in the host side,but without id info:
{"execute":"guest-sync-delimited"}


Actual results:
{"error": {"desc": "Invalid parameter type, expected: integer"}}

Expected results:
{"error": {"class": "InvalidParameterType", "data": {"name": "id", "expected": "integer"}}}

Comment 2 Sameeh Jubran 2017-11-07 12:27:08 UTC 
The error is much clearer now as we dropped the old qemu-ga-win win repository and moved to a qemu-ga-win that is built from upstream qemu (currently qemu 2.9.0).

{"error": {"class": "GenericError", "desc": "Parameter 'id' is missing"}}

I have created an official build, lets test it:

Comment 3 xiagao 2017-11-10 08:32:08 UTC 
Verify this bug on the following pkg:
qemu-ga-win-2.9.2-2.el7ev.noarch
qemu-kvm-rhev-2.9.0-16.el7.x86_64
virtio-win-1.9.3-1.el7.iso

1.Boot win10-64 guest with virtio serial and install/start guest agent.

2. Connect the chardev socket in host side for sending commands to guest:
# nc -U /tmp/qga.sock

3. Send  "guest-ping" command in the host side:
{"execute":"guest-ping"}
{"return": {}}


4. Send "guest-sync-delimited" command in the host side,but without id info:
{"execute":"guest-sync-delimited"}
{"error": {"class": "GenericError", "desc": "Parameter 'id' is missing"}}

The result is expected.
