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.
Previously, it was impossible to start a virtual machine in the REST API if the data center contained an activated ISO domain. This was because the local variable 'volPath' was referenced before it was assigned.
It is now possible to start a virtual machine in the REST API if the data center contains an activated ISO domain.
Description of problem:
Unable to start VM if DC contain an activated ISO domain.
Thread-102::ERROR::2012-07-26 10:54:42,386::vm::604::vm.Vm::(_startUnderlyingVm) vmId=`408f0eb9-2d7a-451d-91d4-01b0d8fd2159`::The vm start process failed
Traceback (most recent call last):
File "/usr/share/vdsm/vm.py", line 570, in _startUnderlyingVm
self._run()
File "/usr/share/vdsm/libvirtvm.py", line 1294, in _run
self.preparePaths(devices[vm.DISK_DEVICES])
File "/usr/share/vdsm/vm.py", line 616, in preparePaths
drive['path'] = self.cif.prepareVolumePath(drive, self.id)
File "/usr/share/vdsm/clientIF.py", line 227, in prepareVolumePath
self.log.info("prepared volume path: %s", volPath)
UnboundLocalError: local variable 'volPath' referenced before assignment
Steps to Reproduce:
1. attach and activate ISO domain
2. Create linux VM from template
3. start VM
Actual results:
Can't start due to "local variable 'volPath' referenced before assignment"
This appears only when creating VM from template using REST API
More specific scenario:
1. add ISO domain
2. Create Template
3. Use REST API to create VM from template
4. Start VM
