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 2022-03-04 06:10:43 UTC 
Description of problem:
qemu-kvm has supported copy/paste in the vnc console since qemu-kvm 6.2.0, see:
Bug 1874926 - [RFE] copy/paste support in qemu VNC console
Bug 2057768 - [RFE]Support copy/paste in the VNC console in libvirt

Virt-install should also support this feature.

Version-Release number of selected component (if applicable):
virt-install-3.2.0-14.el9.noarch
libvirt-8.0.0-6.el9.x86_64
qemu-kvm-6.2.0-11.el9.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Check the sub-option 'clipboard.copypaste' is supported by --graphics.

# virt-install  --graphics=?
--graphics options:
  clearxml
...
  clipboard.copypaste
  connected
  defaultMode
  filetransfer.enable
  gl.enable
  gl.rendernode
  image.compression
  keymap
  listen
  listens[0-9]*.address
  listens[0-9]*.network
  listens[0-9]*.socket
  listens[0-9]*.type
  mouse.mode
  password
  passwordValidTo
  port
  streaming.mode
  tlsPort
  type
  websocket
  zlib.compression

2. Install a VNC VM with "--graphics type=vnc,clipboard.copypaste=yes ".
# virt-install --memory 2048 --location /home/iso/RHEL-7.9-20200917.0-Server-x86_64-dvd1.iso --disk /home/test-agent.img,size=10 --graphics type=vnc,clipboard.copypaste=yes
...
Result - Installation starts successfully.


3. Check the XML content for the graphics setting part.
# virsh dumpxml rhel7.9-2
...
    <graphics type='vnc' port='5902' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
...

Actual results:
Sub-option 'clipboard.copypaste' can't be parsed by virt-install command

Expected results:
Enable vnc copy/paste in virt-install and automatically add a 'qemu-vdagent' channel to the XML for VM.

Additional info:
1. Sub-option 'clipboard.copypaste' can be parsed by virt-install command when add "--dry-run --print-xml"
# virt-install --memory 2048 --location /home/iso/RHEL-7.9-20200917.0-Server-x86_64-dvd1.iso --disk /home/test-agent1.img,size=10 --graphics type=vnc,clipboard.copypaste=yes --dry-run --print-xml
...

    <graphics type="vnc" port="-1">
      <clipboard copypaste="yes"/>
    </graphics>
...

Although it's not clear from this output, several of these options are spice-only, including clipboard.copypaste. Clipboard sharing with VNC is implemented a bit differently in libvirt. There will be no changes to the <graphics> element, but will instead be set on a qemu-vdagent channel element. For example, this is the XML device required to enable this support (assuming a VNC client with clipboard support):

      <channel type='qemu-vdagent'>
        <target type='virtio' name='com.redhat.spice.0'/>
        <source>
          <clipboard copypaste='yes'/>
        </source>
      </channel>


We'll need to add support for this new channel type to virt-install. I'll try to submit this upstream soon.
