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:

I created a Direct lun with IDE interface and attached it to a vm. 
the first run of the vm fails with: Bad volume specification

after I attached a second direct lun which was virtio, I was able to run the vm but I can see in the xml that the disk interface was change to virtio. 

Version-Release number of selected component (if applicable):

si6

How reproducible:

100%

Steps to Reproduce:
1. create a direct lun with IDE disk and attach it to a vm
2. run the vm -> run will fail
3. attach a second direct lun with virtio disk - Run the vm 

Actual results:

IDE disk will fail to run. once we add a second virtio disk the vm ran but both disks were run with virtio. 

Expected results:

we should be able to run a direct lun with IDE interface.

Comment 1 Eduardo Warszawski 2012-08-09 07:24:26 UTC 
Starting a VM with direct LUN functionality was verified.

This is another instance of the /dev/mapper update race with connectStorageServer and the following operation using the new devices.

Can be solved in the engine level.

We are studying host level (vdsm) solutions.
