Hi all,
Trying to copy from guest and paste into host not working.
I have:
host: Manjaro stable updated up to today - plasma - wayland - KVM
guest1: Manjaro stable updated up to today - plasma - wayland - quemu-guest-agent installed
quest2: Debian 13 updated up to today - plasma - wayland - quemu-guest-agent installed
Copy from host and paste into guest working with any host
Copy from any guest and paste into host NOT WORKING
All tests were done using Konsole
What I’m missing?
Copy and paste are bidirectional active between my host and my guest (both KDE).
I greped these packages as installed on the host and in the details menu of virtman the memory configuration shows checkbox as active for shared memory:

Have you read this?
It mentions wl-clipboard, and spice-vdagent with qemu-vdagent, though as you’re using wayland you probably want the first one.
I am pretty sure copy/paste is all done through spice-vdagent. Which you need a functioning SPICE server on the hypervisor to talk to as well.
I have SPICE disabled since I use GPU pass-through. But even in a window on the host, I have never been able to copy/paste, since I don’t run it.
Hi @Acor and @Teo I’ve tried to compare the installed packages
Please note I’m using wayland and have an AMD gpu.
I have the same packages as @Teo (the only difference is X11 vs Wayland); so maybe there is some difference in the vm created with virtual manager.
In my configuration:
HOST
Plasma Wayland AMDgpu KVM qemu
GUEST
Plasma Wayland
screen spice
<graphics type="spice" port="-1" autoport="no">
<listen type="address"/>
<image compression="off"/>
<gl enable="no"/>
</graphics>
video virtio

Still looking for what I’m missing

I did a quick test just now
Select and copy text from the virtual machine, gives this on the host
\EF\8C\92 \EE\82\B0 \EF\80\95 ~ \EE\82\B0 this is a test \EE\82\B2 \E2\9C\94
zsh: correct 'this' to 'tic' [nyae]? n
zsh: command not found: this
Well,
qemu-vdagent is not between installable packages
spice-vdagent was already installed
wl-clipboard was missing. I installed it but nothing changed
Thanks
I tried
What I described was done with a default Manjaro Gnome using kernel virtual machine (KVM).
One could speculate it is Plasma related, so I will test with the new KVM using Plasma minimal ISO of 260206.
Thanks
BTW one of the guest was installed from manjaro-kde-26.0-260104-linux618.iso and then updtated up to today
My computer and grahics are AMD, too, and I use wayland on KDE (sddm).
In /etc/group of host computer I’ve found my desktop user in groups kvm, libvirt and libvirt-qemu.
wl-wayland was installed on host even before my kvm/qemu installation, among other files containing these binaries:
# ls -1 /usr/bin/wl-*
/usr/bin/wl-copy
/usr/bin/wl-paste
(On the guest they are NOT installed)
On the guest I found just the Qemu guest agent in package list:
$ pacman -Q |grep -Ei 'kvm|qemu|libvirt'
qemu-guest-agent 10.1.0-1
Verifying. I’ll report here
TL;DR
On host I belong to groups:
[mirto@bianco500 ~]$ id
uid=1000(mirto) gid=1000(mirto) gruppi=1000(mirto),3(sys),90(network),98(power),958(libvirt-qemu),959(libvirt),991(lp),992(kvm),998(wheel)
[mirto@bianco500 ~]$
Wl packages are missing on host
The 2 packages belong to the wl-clipboard package.
I’ll try to install and I’ll report here
[mirto@bianco500 ~]$ sudo ls -1 /usr/bin/wl-*

[mirto@manjaro ~]$
The default group membership for the first user on a Manjaro Linux installation is
# addgroups="lp,network,power,wheel"
– manjaro/kde/profile.conf · master · Profiles & Settings / iso-profiles · GitLab
The profile for building the Gnome edition is extending the default
addgroups="lp,network,power,wheel,users,storage,input,audio"
– manjaro/gnome/profile.conf · master · Profiles & Settings / iso-profiles · GitLab
This difference is a maintainer decision - it is how it is, no questions asked, no blame casted.
The copy/paste from a KVM guest to the host depends on the membership of the input group.
Thus for the issue at hand - a Manjaro Gnome will behave different than a Manjaro Plasma virtual machine.
Inside the Plasma guest - add the user to the input group, and the copy/paste from guest to host will be activated upon next sign-in.
sudo gpasswd -a $USER input
Remember to sign off and sign in to activate the group (or reboot).
This seems to be a mess.
copy-paste by just highlighting text with the mouse works normally
when host and guest are running x11
It only works for host to guest when guest is running wayland - not the other way around.
(no copy paste from guest to host)
And it only works when using the context menu -
when explicitly selecting “copy” and then “paste” on the other side.
Just highlighting text isn’t enough anymore.
My host is Xfce4 - can’t run wayland there, can’t explore this further.
Am I glad not to be forced to use wayland. 
No luck
Installed wl-clipboard rebooted and tried: nothing changed
Your issue is group membership - See my comment above 
Your guest user is not member of input group.
Check the output of groups command when signed in.
I didn’t say anything about the host user - only the guest.
It is a mystery then.
As I promised above I tested with a minimal Plasma and precisely that change - adding the guest user to input group - made the difference between working and not working.
Oh SORRY, my host desktop is KDE but on guest is xfce!
