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 zhoujunqin 2014-09-15 06:50:10 UTC 
Description of problem:
virt-v2v: error: access: No such file or directory shows when converting xen/esx guests

Version-Release number of selected component (if applicable):
virt-v2v-1.27.45-1.1.el7.x86_64
libguestfs-1.27.45-1.1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Run virt-v2v to connect a xen guest.
xen server: 10.66.106.64
1.1
# virsh -c xen+ssh://10.66.106.64 list --all
 Id    Name                           State

virt-v2v: error: access: No such file or directory:
/var/lib/xen/images/rhel6.6-pv-x64-test.img

If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:

  virt-v2v -v -x [...]

1.3 check on xen server, imgage file exists.

2.Run virt-v2v to connect a esx guest.
# virt-v2v -ic vpx://10.66.7.125/tzheng-test/10.66.71.84/?no_verify=1 esx5.1-clone-test -v -x

Comment 2 Richard W.M. Jones 2014-09-15 07:48:56 UTC 
Ugh, my fix for bug 1140946 unintentionally broke remote disks.
Commit 73c1f1cf7e1c4aa4e70407feff49ba847f7ebb63 is the broken commit.
Comment 3 Richard W.M. Jones 2014-09-15 08:50:34 UTC 
I've decided simply to revert the above commit, and not to
try to add a nicer error message for bug 1140946.  The revert
commit is:

https://github.com/libguestfs/libguestfs/commit/be1385d2cbf198606c1d11c0302de6b11176d785

This fix will appear in libguestfs 1.27.46.
Comment 5 zhoujunqin 2014-09-16 09:56:39 UTC 
I can reproduce this bug as Comment 0 said.
And try to verify with new build:
virt-v2v-1.27.46-1.1.el7.x86_64
libguestfs-1.27.46-1.1.el7.x86_64

steps:
1. Run virt-v2v to connect a xen guest.

[ 164.0] Finishing off

2. Run virt-v2v to connect a esx guest.
# virt-v2v -ic vpx://administrator.7.125/tzheng-test/10.66.71.84/?no_verify=1  esx-rhel6

Since conversion is successful and no error like Comment 0 shows, move this from ON_QA to VERIFIED.
