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 5 tingting zheng 2014-04-17 07:38:46 UTC 
Tested pass with:
libvirt-0.10.2-33.el6.x86_64

Steps:
1.Prepare a guest.
2.Plug in a usb device on host with usbredir packages installed.
# lsusb
Bus 002 Device 002: ID 0951:1625 Kingston Technology DataTraveler 101 II
 
# usbredirserver -p 4000 0951:1625

3. Configure the guest with Redirected USB Device with tcp type.

4. Boot the guest.

5.Use virsh dumpxml to get the xml of the guest.
# virsh dumpxml mig > mig.xml
……
    <redirdev bus='usb' type='tcp'>
      <source mode='connect' host='$ip' service='4000'/>
      <protocol type='raw'/>
    </redirdev>
……

6.Change the type in xml from 'tcp' to 'spicevmc'.
change xml from:
    <redirdev bus='usb' type='tcp'>
      <source mode='connect' host='$ip' service='4000'/>
      <protocol type='raw'/>
    </redirdev>
to:
    <redirdev bus='usb' type='spicevmc'>
      <source mode='connect' host='$ip' service='4000'/>
      <protocol type='raw'/>
    </redirdev>

7.Do migrate,error shows:
# virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml
error: unsupported configuration: Target redirected device source type spicevmc does not match source device source type tcp

8.Edit in xml to add one more usb redirdev,add the below part in mig.xml:
    <redirdev bus='usb' type='spicevmc'>
      <alias name='redir1'/>
    </redirdev>

9.Do migrate,error shows:
# virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml
error: unsupported configuration: Target domain redirected devices count 2 does not match source 1
