- Not working from client to guest is the only issue?

- When you say 'cut and paste' is it a string that you are selecting with your mouse in some application or a file?

- If you are running on Wayland can you try using an X11 session to see if it works?

I can't cut and paste from the host to the clients. I work a lot with different guests, and I need to cut and paste commands or scripts from the host (my workstation) to the guests (which are spot vms I use and destroy). I was able to do it with fedora 24 but I have never been able to do it with fedora 26. I can cut from a guest and cut to the host, but I need to do the contrary. Yes, I am using Wayland and will try to switch back to X.
if I check the service with the "verygoodinitdreplacement" systemd I get:

systemctl status spice-vdagentd.service
● spice-vdagentd.service - Agent daemon for Spice guests
   Loaded: loaded (/usr/lib/systemd/system/spice-vdagentd.service; enabled; vendor preset: enabled)
   Active: inactive (dead)


which tells me there is a problem (the service started but there was an issue).
checking the boot sequence I get:

Sep 09 15:15:29 <hoatname> spice-vdagent[1880]: Cannot access vdagent virtio channel /dev/virtio-ports/com.redhat.spice.0

and if i check if the device file does exist, I can't even find the directory virtio-ports in /dev.

/dev/virtio-ports/com.redhat.spice.0 not existing would be your first issue. Does that always happen? Only sometimes? However, when it's missing, I'd expect copy and paste to not be functional at all.

Copy and paste working from guest to host, but not the other way round is a totally different issue, and is related to wayland.

update: using Xorg instead of Wayland fixes this issue (and I have to say that the mouse movements are smoother than before).

anyway /dev/virtio-ports/com.redhat.spice.0 is NEVER created. I checked on both my workstations. So I guess we have an issue here, which does not affect the cut and paste stuff anyway.
Switching back to xorg seems a workaround, nut i guess both problems should be fixed

Just to be sure, you are checking this device in the guest VM right, not in the host/client.

It would not be possible to have things working without this device.

nope, I am able to cut and paste between the host and the guests. I am doing this right now.

have a look below:

journalctl -b|grep virtio

the wayland side is a bug upstream.

My question in comment #5 was if you are checking the spice-vdagent in the VM or in the HOST. There is no need to run spice-vdagent in the HOST and in the HOST we don't have the virtio-port which would explain your concern.

sorry about that, I misunderstood then. aswering tour question, yes, I am running vdagent in the guest. spice-vdagent starts by default (fedora 26), I didn't touch it. SWo i guess I can disable the service than. So I guess my issue should be moved to wayland than. another issue I have is that if a cntr-tab in full screen in a guest, the key conbination is intercepted by wayland (I see processes running in the host). thanks for your explanation.

and I guess that vdagentd is enabled by default in case fedora runs as a guest :-)

This can be a real bug maybe selinux :

1. Can the distro get provider CISCO access like a "virtual machine" ( ... SYSLOG_PID	1672 with _GID	1000 ) into area using a device on BNC (Bayonet Neill-Concelman) 

2. The logs from server Fedora also show selinux issue:
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
