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.

2. guestfish -x -v add-drive-ro-with-if ide.img ide : add-drive-ro-with-if =
virtio.img virtio : run : list-devices=20
3. no problem with:  guestfish -x -v add-drive ide.img : add-drive virtio.i=
mg  : run : list-devices

Comment 3 Richard W.M. Jones 2012-09-28 13:21:09 UTC 
I can reproduce this bug in RHEL 6.4.

Upstream, the same command hangs libguestfs ...  This
is not necessarily surprising because (upstream) this
tries to add an IDE disk, a virtio-blk disk, and a virtio-scsi
disk to the same guest, which seems unlikely to work,
and even less likely to be a good idea.

However I will try to fix this for RHEL 6.
Comment 4 Richard W.M. Jones 2012-09-28 14:09:36 UTC 
Fixed upstream in commit d57511e00c9e40ea895edd48953f3ab094a29bb0.

Ignore that.
