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.

    machines: Fix incorrect disk format when attaching existing volume
    
    If you attach existing volume as a disk, default storage pool format
    would be used as disk format. That's however not correct, as we should
    use volume's format type as a disk's format type.
    Pool's default format type should be used only as a fallback when volume's
    format type is not present.
Comment 3 Xianghua Chen 2019-12-09 07:02:24 UTC 
Verified with packages:
cockpit-machines-208-1.el8.noarch
libvirt-dbus-1.2.0-3.module+el8.1.0+4066+0f1aadab.x86_64

Steps:
1. Create an raw disk by :
# virsh vol-create-as default raw-disk 1G --format raw
2. Login cockpit and Create a VM
3. Switch to the disk tab of the VM, click "Add Disk"
4. Choose "Use Existing" and the new created volume: raw-disk, click Add

The prepared raw disk can be attached successfully.
