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.

Comment 4 Richard W.M. Jones 2018-08-09 09:28:33 UTC 
Sorry I missed this bug because I was on holiday.  We had another
user reporting the same issue last week, and I absolutely cannot
find the BZ for that right now.  Still looking ...
Comment 5 Richard W.M. Jones 2018-08-09 09:39:19 UTC 
I still cannot find it.  In any case this issue is fixed in RHEL 7.6
and libguestfs 1.38.
Comment 6 Richard W.M. Jones 2018-08-09 10:25:23 UTC 
Reproducer (on 1.36.10-6.16.rhvpreview.el7ev):

$ guestfish scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 10M : run : part-disk /dev/sdp mbr : blockdev-getsize64 /dev/sdp1 : part-to-dev /dev/sdp1 
10355200
/dev/sd     <-- incorrect

Does not reproduce in 1.38:

$ guestfish scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 1M : scratch 10M : run : part-disk /dev/sdp mbr : blockdev-getsize64 /dev/sdp1 : part-to-dev /dev/sdp1 
10355200
/dev/sdp    <--- correct

So this will be fixed by upgrading to RHEL 7.6.
Comment 8 Pino Toscano 2018-08-09 10:36:55 UTC 
Fixed by rebase.
Comment 10 mxie@redhat.com 2018-08-15 09:11:38 UTC 
I can reproduce the bug with builds:
virt-v2v-1.36.3-6.el7_4.3.x86_64
libguestfs-1.36.3-6.el7_4.3.x86_64
libvirt-4.5.0-6.el7.x86_64
qemu-kvm-rhev-2.12.0-10.el7.x86_64

Steps to reproduce:
1.Prepare a rhel5 guest on ESXi6.7 host, add 19 additional disks to guest and make partition for additional disks (/dev/sdb1 to /dev/sdt1)

2.Convert the guest from vmware by virt-v2v, the conversion is failed with same error with bug
