QEMU / KVM : Spice Console unable to connect to VM in KVM

fanoflq · 08-16-2016, 10:04 AM

Scenario:
In Linux Mint 18 -Cinnamon (Ubuntu 16) host, started CentOS7 VM in KVM via virt-manager.
then I clicked "Open" icon to show virtual machine (graphical) console and details. This would be the display for QEMU / KVM console.

and I got this error in

Quote:

"Error connecting to graphical console:
Error opening spice console, SpiceClientGtk missing"

On VM CentOS 7 side,I found this log messages when I connect using virt-viewer instead of failed connection using Spice console:

Quote:

[root@localhost ~]# cat /var/log/messages | grep avc
...
type=AVC msg=audit(1471235537.999:359): avc: denied { getattr } for pid=2302 comm="spice-vdagent" path="/dev/vport0p2" dev="devtmpfs" ino=432 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u: object_r:virtio_device_t:s0 tclass=chr_file
...

So I fixed the error above related to SELinux.
meaning it no longer shows up in the CentOs7 (VM) log messages

But I still am not able to connect using Spice console and still get this error on Linux Mint host side:

Quote:

"Error connecting to graphical console:
Error opening spice console, SpiceClientGtk missing"

On Linux Mint host side, I also already have the missing SpiceClientGtk:

Quote:

$ apt-file find SpiceClientGtk
gir1.2-spice-client-gtk-2.0: /usr/lib/girepository-1.0/SpiceClientGtk-2.0.typelib
gir1.2-spice-client-gtk-3.0: /usr/lib/girepository-1.0/SpiceClientGtk-3.0.typelib
libspice-client-gtk-2.0-dev: /usr/share/gir-1.0/SpiceClientGtk-2.0.gir
libspice-client-gtk-3.0-dev: /usr/share/gir-1.0/SpiceClientGtk-3.0.gir
python-spice-client-gtk: /usr/lib/python2.7/dist-packages/SpiceClientGtk.so

Note that the setting for display on virt-manager's "virtual hardware details tab" (click "Open" then in new window click "i" icon) for display are:
Display: type = Spice Server, Address = Localhost only, Port=5900 (Auto)
Video: Model= QXL

What is causing this problem on host side?
Thank you.

Hi. I had the same error and i fixed it thusly:
sudo apt-get install python-spice-client-gtk
sudo apt-get install virt-viewer

Those packages were already installed.
What is your host Linux distro?

lethein · 08-19-2016, 01:37 AM

It's Linux Mint 18 xfce. I also have KVM on Fedora 24 and there weren't any error messages there.

@lethein:

I am using Linux Mint 18, Cinnamon.
Spice console is still not working....

Luckily, virt-viewer is working.
Still do not know why ...

If you ever install LM 18 - Cinnamon,
Let me know your result with KVM & Spice console..

Thanks.

If you install virt-manager from the installation DVD, there is a missing "recommends" package on the DVD. crtlbreak mentions this package above.

Me too, I just registered to thank you. I'm running KVM on Linux Mint 18.3 Cinnamon.

Hi, I got the same error message and executing the above install got me a 'no package found' error from apt-get.
However, when searching Synaptic Package Manager, I found gir1.2-spiceclientgtk-3.0 (notice the dashes left out), which I could install and fixed the error (after restarting libvirtd.service and virt-manager).

So, I guess for Linux Mint 19 use:

Code:

sudo apt-get install gir1.2-spiceclientgtk-3.0
