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.

Red Hat Product Errata RHEA-2011:1782 0 normal SHIPPED_LIVE new packages: vdsm 2011-12-06 11:55:51 UTC

Description Jakub Libosvar 2011-04-20 15:10:12 UTC 
Description of problem:
Machines are imported with 740 permissions instead of 660 - this lead to impossibility of rhel6 host to run VMs.

Version-Release number of selected component (if applicable):
vdsm22-4.5-63.25.el5_6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Import VM to mixed DC with rhel5.6 SPM 
2. Run VM in 2.3 cluster
  
Actual results:
Run fails

Expected results:
VM runs

Additional info:
Attempt to run fails due to insufficient permissions for image file on storage (740 instead of 660).
Comment 1 Dan Kenigsberg 2011-04-23 18:37:01 UTC 
vdsm-4.9 should behave well with images imported by vdsm22-4.5-63.25 or older.
Comment 2 Jakub Libosvar 2011-04-26 08:22:53 UTC 
Another way to get to this state is creating snapshot of VM's disk while SPM is host with vdsm22, then start VM on host with vdsm.

Comment 5 Tomer 2011-05-16 12:11:43 UTC 
Scenario to reproduce the bug:

1. Add new cluster(2.3) to existing data center(2.2).
2. Create VM on new cluster.
3. try to run the VM.

VM fails to run due to permission denied when trying to access to snapshot image.
