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.

guestfish log

Description of problem:
The duplicate block device is listed when iface is set to 'virtio'.


Version-Release number of selected component (if applicable):
libguestfs-1.42.0-1.module+el8.3.0+6496+d39ac712.x86_64
qemu-kvm-4.2.0-19.module+el8.3.0+6478+69f490bb.x86_64
kernel-4.18.0-208.el8.x86_64


How reproducible:
100%


Steps:

1. On rhel8.3 host
# qemu-img create virtio.img 1G
Formatting 'virtio.img', fmt=raw size=1073741824

2.
# LIBGUESTFS_BACKEND=direct guestfish

Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.

Type: ‘help’ for help on commands
      ‘man’ to read the manual
      ‘quit’ to quit the shell

><fs> add-drive virtio.img iface:virtio
><fs> run
><fs> list-devices
/dev/sda
/dev/sda
><fs> list-filesystems
/dev/sda: unknown
/dev/sda: unknown
><fs> quit


Actual results:
as above

Expected results:
Only one block device(/dev/sda) is listed.


Additional info:
No problem when iface is set to 'ide'
Comment 1 Richard W.M. Jones 2020-06-05 09:54:50 UTC 
One line reproducer is:

$ LIBGUESTFS_BACKEND=direct guestfish add-drive /dev/null iface:virtio : run : list-devices
/dev/sda
/dev/sda

The libvirt backend has never allowed the iface parameter.  We should
probably ignore it in the direct backend since it's never been possible
to use this parameter correctly.

Ok, i see. Thanks you.

Test with libguestfs-1.48.2-2.el9.x86_64 on RHEL9.1 host:

$ LIBGUESTFS_BACKEND=direct guestfish add-drive /dev/null iface:virtio : run : list-devices
/dev/sda

The result is expected.
