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 08:38:19 UTC 
Description of problem:
virt-v2 should support convert a domain with using domain's UUID instead of domain name

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. Prepare a health guest on xen server.
# virsh -c xen+ssh://10.66.106.64 dumpxml rhel6.6-pv-x64-test
<domain type='xen'>
  <name>rhel6.6-pv-x64-test</name>
  <uuid>1be6394a-de41-c664-e3c6-86fc2c158b93</uuid>
  <memory>524288</memory>
  <currentMemory>524288</currentMemory>
  <vcpu>1</vcpu>
  <bootloader>/usr/bin/pygrub</bootloader>
  <os>
    <type arch='x86_64' machine='xenpv'>linux</type>
  </os>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <disk type='file' device='disk'>
      <driver name='tap' type='aio'/>
      <source file='/var/lib/xen/images/rhel6.6-pv-x64-test.img'/>
      <target dev='xvda' bus='xen'/>
    </disk>
    <interface type='bridge'>
      <mac address='00:16:3e:7b:e3:58'/>
      <source bridge='xenbr0'/>
      <script path='vif-bridge'/>
    </interface>
    <console type='pty'>
      <target port='0'/>
    </console>
    <input type='mouse' bus='xen'/>
    <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
  </devices>
</domain>

2. when converting a guest from xen server, using -ic xen+ssh://root@xen [...]

# ssh-keygen
# ssh-copy-id -i /root/.ssh/id_rsa.pub root@$xenserver
# eval `ssh-agent`
# ssh-add
using domain's uuid instead of domain's name.
# virt-v2v -ic xen+ssh://10.66.106.64 -os /var/tmp 1be6394a-de41-c664-e3c6-86fc2c158b93
[   0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 1be6394a-de41-c664-e3c6-86fc2c158b93
libvirt: Xen Driver error : Domain not found: xenUnifiedDomainLookupByName
virt-v2v: error: internal error: invalid argument: cannot find libvirt 
domain '1be6394a-de41-c664-e3c6-86fc2c158b93'

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

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

result: conversion failed.

Actual results:
virt-v2v cannot support convert a domain with using domain's UUID instead of domain name

Expected results:
virt-v2 should support convert a domain with using domain's UUID instead of domain name

Comment 4 zhoujunqin 2014-09-16 08:37:23 UTC 
Try to verify with new build:
libguestfs-1.27.46-1.1.el7.x86_64
virt-v2v-1.27.46-1.1.el7.x86_64

steps:
Using domain's UUID when converting a domain from xen server:
# virsh  -c xen+ssh://10.66.106.64 dominfo rhel6.6-pv-x64-test
Id:             -
Name:           rhel6.6-pv-x64-test

since using a domain's uuid when conversion works well, move this bug from ON_QA to verified.
