Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
If set migrate_set_downtime with negative number in qmp, qmp do not give any warning or error message. I also test with other illegal number, such as "00.1234" and "abc" and so on, it will give some error messages.

{"error": {"class": "GenericError", "desc": "Invalid JSON syntax"}}
{"error": {"class": "GenericError", "desc": "Invalid JSON syntax"}}
{"error": {"class": "GenericError", "desc": "Expected 'object' in QMP input"}}

Version-Release number of selected component (if applicable):
qemu-kvm-1.5.3-2.el7.x86_64
3.10.0-18.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.run qemu-kvm with following command.
# /usr/libexec/qemu-kvm -monitor stdio -qmp tcp:0:4445,server,nowait
2.run "migrate_set_downtime" with negative number inside qmp.
{ "execute": "migrate_set_downtime", "arguments": { "value": -2342345346}}
{ "execute": "migrate_set_downtime", "arguments": { "value": -0.2342}}
3.observe the return result inside qmp.
Actual results:
{"return": {}}
{"return": {}}
Expected results:
When run "migrate_set_downtime" with negative number, qmp will give some warning or error message.
Additional info:
Direct usage of QMP will not be supported in RHEL7 and libvirt should protect us from this kind of usage.
In fact, QMP negative numbers (signed) are used sometimes at the JSON level and then converted to signed internally, to workaround a limit on the size accepted by the JSON parser. Which is probably not the case here, but anyway, closing as WONTFIX because this will not be a supported scenario in RHEL7.
