1159030 – libvirt backend does not set RBD password

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 Daniel Berrangé 2014-10-30 17:52:32 UTC

+++ This bug was initially created as a clone of Bug #1159016 +++

Description of problem:
After configuring an RBD disk with libguestfs I get this error when launching the appliance


2014-10-30 16:53:24.859 TRACE nova.compute.manager [instance: 3f8c2d01-4b07-4864-b3ed-7a45bc2b95bd] Original error from libvirt: XML error: missing auth secret uuid or usage attribute [code=27 domain=18])

Forcing the backend to 'direct' successfully launches

I can see the XML libguesfs builds is:

    <disk device="disk" type="network">
      <source protocol="rbd" name="2f98aa3a-c005-4c21-8fb3-595a5a698005_disk/vms">
        <host name="10.33.9.42" port="6789"/>
      </source>
      <auth username="cinder"/>
      <target dev="sda" bus="scsi"/>
      <driver name="qemu" type="raw" cache="writeback"/>
      <address type="drive" controller="0" bus="0" target="0" unit="0"/>
    </disk>

The auth XML element should refer to a secret

      <auth username="cinder">
        <secret type="ceph" uuid="457eb676-33da-42ec-9a8c-9293d545c337"/>
      </auth>


Version-Release number of selected component (if applicable):
libguestfs-1.26.9-1.fc20.x86_64

--- Additional comment from Daniel Berrange on 2014-10-30 17:51:36 GMT ---

Ah ha, seems this is a known todo item

          start_element ("auth") {
            attribute ("username", drv->src.username);
            /* TODO: write the drive secret, after first storing it separately
             * in libvirt
             */
          } end_element ();

Upstream commit:
https://github.com/libguestfs/libguestfs/commit/6d6644d52d8092dd4f4add859ebda06bea4b5b56

Comment 7 Richard W.M. Jones 2015-04-13 14:23:21 UTC

Note that in order to implement this fix, I had to enable
rbd (Ceph) support in libguestfs in RHEL 7.2.

Comment 9 Hu Zhang 2015-10-10 08:22:49 UTC

Verified with the packages:
libguestfs-1.28.1-1.55.el7.x86_64

Verify steps:
1. Configuring an RBD disk. Add a user libguestfs.
2. On client:
# guestfish
><fs> add-drive gs/gs1.img format:raw protocol:rbd server:hostname:6789 username:libguestfs secret:$key
><fs> run
><fs> part-disk /dev/sda mbr
><fs> list-filesystems 
/dev/sda1: unknown
><fs> mkfs ext3 /dev/sda1
><fs> mount /dev/sda1 /
><fs> ls /
lost+found

So verified.
