noVNC copy/paste from guest to host

[NV.Kormiltcev]

Hi everyone. I have a problem and i can't find useful information about copy/paste from guest to host. I tried to use information from https://forum.proxmox.com/threads/mod-add-paste-clipboard-to-novnc.42549/. It isn't working. I need only noVNC.
Can anybody help me?

I made a patch-series for using the noVNC Clipboard.
You can wait till the patch-series got applied or patch it yourself with git am <email-patch-file> in qemu-server, novnc-pve, pve-manager.

Hi, i don't understand...
i correct my QemuServer.pm as step 1/5 https://lists.proxmox.com/pipermail/pve-devel/2022-September/053857.html.
But, when i start novnc, clipboard don't work.
Can you get more deatil of instructions?

Remember that this has not been tested and is not meant for production use right now and you would have to do this after every update.

to activate add clipboard=1 to vga in your vm config.

vga: std,clipboard=1

Simpler Solution:

What the clipboard-feature really needs are these 3 qemu parameters:

qemu-system-x86_64 [ ... ] \
  -chardev qemu-vdagent,id=ch1,name=vdagent,clipboard=on \
  -device virtio-serial-pci \
  -device virtserialport,chardev=ch1,id=ch1,name=com.redhat.spice.0

You can get your qemu-command with qm showcmd 191 --pretty and then add the parameters above.

And you need to remove the pve-hidden class from noVNC_clipboard_button in javascript and click the button on left side.

[MarkusF]

Do not use spaces between qemu-vdagent,id=vdagent,name=vdagent,clipboard=on

It tells you Invalid parameter ' id' because of the space.

I done as instruction, now i got this error

kvm: -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3: PCI: slot 3 function 0 not available for virtio-balloon-pci, in use by virtio-serial-pci
TASK ERROR: start failed: QEMU exited with code 1

help pls, how i repair?

 

[MarkusF]

Either move the three parameters to the end of qemu-command or add a bus and addr parameter with an address you do not use.

-device virtio-serial-pci,bus=pci.0,addr=0x9

Thanks that reminds to add these parameters to the patch.

I solve problem, i need to use
-device virtio-serial-pci,bus=pci.0,addr=4

 

[MarkusF]

I would use addr=0x9 since it is used by spice which cannot run at the same time

Do not forget to install spice-vdagent and enable clipboard with the button in noVNC
