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 Douglas Schilling Landgraf 2011-01-01 01:42:51 UTC 
Description of problem:

virt-v2v reports the following error messages when it migrates from a
RHEL4.8 VMware ESX's guest OS.

Version-Release number of selected component (if applicable):
virt-v2v-0.6.2-4.el6.x86_64

How reproducible:
# virt-v2v -ic esx://192.168.1.10/?no_verify=1 -op default --bridge br0 rhel48_34
** HEAD https://192.168.1.10/folder/rhel48_34/rhel48_34-flat.vmdk?dcPath=ha-datacenter&dsName=local_disk ==> 401 Unauthorized

Comment 5 Rita Wu 2011-01-27 04:04:11 UTC 
Verified with libguestfs-1.7.17-11.el6.x86_64 + virt-v2v-0.7.1-1.el6.x86_64.

Before conversion, the rhel4u8 guest has fd0 in /boot/grub.device.map
(fd0) /dev/fd0
(hd0) /dev/xvda

During conversion there is no unknown filesystem /dev/fd0 any more, so set it as VERIFIED.

If the /etc/fstab of a guest machine contained a reference to a floppy disk (/dev/fd0), both virt-inspector and virt-v2v printed the following harmless warning during inspection or conversion:

unknown filesystem /dev/fd0

This warning has been suppressed to avoid confusion, and should no longer appear even if the guest machine refers to floppy disks in /etc/fstab.
