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 tingting zheng 2012-12-20 07:45:12 UTC 
Description of problem:
[RFE]virt-p2v should check whether guest with same name exist on target first then transfer the disk

Version-Release number of selected component (if applicable):
virt-v2v-0.8.9-2.el6.x86_64
RHEL6.4-20121212.1-Server-i386-P2V.iso

How reproducible:
100%

Steps to Reproduce:
1.Use virt-p2v to convert a physical machine,on the virt-p2v client GUI,type the guest name which already exists on target host.

2.Click convert.The conversion will begin,after spending a lot of time to transfer the whole disk,error shows:virt-v2v: libvirt error code: 9, message: operation failed: domain 'demo-test' already exists with uuid 40bf1863-1740-539c-88df-032a62cef740

3.Use virt-v2v to convert a guest with the name which already exists on target,it checks the target and quits instead of transferring the disk.
# virt-v2v -ic qemu+ssh://10.66.6.128/system -os default -b br0 test
root.6.128's password: 
virt-v2v: Domain test already exists on the target.

Actual results:
As steps describe.

Expected results:
virt-p2v works as virt-v2v,check whether guest with same name exist on target first then transfer the disk.

Additional info:
Comment 1 Matthew Booth 2012-12-21 12:44:37 UTC 
Yup. virt-v2v does this, virt-p2v should do it too.
Comment 2 RHEL Program Management 2013-10-14 04:29:27 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 5 Richard W.M. Jones 2015-05-05 14:45:05 UTC 
Although the bug mentions virt-p2v, in fact it's the job of
virt-v2v to check on the target for the guest with the same
name.  (virt-p2v uses virt-v2v, so hopefully that will solve
the problem for virt-v2v too.)

I have adjusted the summary accordingly.

Comment 11 tingting zheng 2015-06-18 06:14:40 UTC 
Tested with:
virt-v2v-1.28.1-1.38.el7.x86_64
libguestfs-1.28.1-1.38.el7.x86_64

1.Make sure on my host,there is guest named "esx6.0-win2008-x86_64" exist.
# virsh list --all
 Id    Name                           State
----------------------------------------------------
 36    win7-vcenter                   running
 -     esx6.0-win2008-i386            shut off
 -     esx6.0-win2008-x86_64          shut off
 -     p2v-network-test               shut off
 -     rhel6.7-x64                    shut off
 -     rhel7.1-x64                    shut off

2.Use virt-v2v to convert guest which already exist on the host.
# virt-v2v -ic vpx://root.72.112/data/10.66.72.49/?no_verify=1 -os default -b virbr0  --password-file /tmp/passwd2 esx6.0-win2008-x86_64
[   0.0] Opening the source -i libvirt -ic vpx://root.72.112/data/10.66.72.49/?no_verify=1 esx6.0-win2008-x86_64
[   1.0] Creating an overlay to protect the source from being modified
[   2.0] Opening the overlay
[  14.0] Initializing the target -o libvirt -os default
virt-v2v: error: a libvirt domain called 'esx6.0-win2008-x86_64' already 
exists on the target.

If using virt-v2v directly, use the '-on' option to select a different 
name. If using virt-p2v, select a different 'Name' in the 'Target 
properties'. Or delete the existing domain on the target using the 'virsh 
undefine' command.

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

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

There is error about guest already exists on the target before conversion.

Tried about virt-p2v,the similar error showed and conversion didn't start.

Refer to the above comments,move the bug to VERIFIED.
