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 Marian Krcmarik 2011-08-03 11:44:40 UTC 
Description of problem:
I am getting an error when spice password is set in domain:
error: Failed to start domain WinXP
error: internal error unable to execute QEMU command '__com.redhat_set_password': Invalid JSON syntax - which means that It's no possible to start Domain.
I believe This is fixed in repo already (based on discussion with Michal (mprivozn), anyway creating a bug for tracking that and making sure It will be retested and included in test cases.

Version-Release number of selected component (if applicable):
libvirt-0.9.4-0rc2.el6

How reproducible:
Always

Steps to Reproduce:
1. Start a Domain using virsh with spice password set (attribute passwd in graphics element)
  
Actual results:
error: internal error unable to execute QEMU command '__com.redhat_set_password': Invalid JSON syntax

Expected results:
Started Domain

Please provide the /var/log/libvirt/libvirtd.log file for the host, so that we can see the JSON data sent to QEMU

Comment 3 Daniel Berrangé 2011-08-03 12:11:39 UTC 
This shows the flaw:

> {"execute":"__com.redhat_set_password","arguments" {"protocol":"spice","password":"12345","connected":null,"expiration":195},"id":"libvirt-5"}:

the 'connected' attribute is 'null' which is not a valid string. THis is introduced by the custom patch

libvirt-Support-password-expiry-and-connected-in-the-QEMU-driver.patch

which was not rebased correctly for libvirt 0.9.4

Good, In that case this build should not pass QE consumption and should be mentioned in Acceptance testing results.
Libvirt QE, please make sure for next time.
As well as it's regression between libvirt-0.9.4-0rc1.2 and libvirt-0.9.4-0rc2.
This bug report was to make sure It will really get in next realese.
Thanks.
