Greetings!
This an openSuse Leap-15.3 installation.
I’m running KVM on server ‘KVM1’ with KVM-guest ‘MAG1’.
GDM is the display-manager on KVM1.
To have the guest GUI available I’m using XDMCP and start the guest GUI with
nohup /usr/bin/Xorg :8.0 vt8 -query MAG1
Switchung between KVM1 server GUI and guest GUI is done with
Ctrl + Alt + F7 and Ctrl + Alt + F8
Works as requred.
However
after running
ssh wg@KVM1 'sudo /root/remountUSB.sh'
on MAG1 guest several times I cannot switch to KVM1 server.
/root/remountUSB.sh:
#!/bin/bash
/usr/bin/virsh detach-device MAG1 /root/$USB_MODEM.xml
/usr/bin/virsh attach-device MAG1 /root/$USB_MODEM.xml
The guest MAG1 is still running ok.
I can reach KVM1 server via
ssh **root**@KVM1
the prompt and password dialog appears as expected.
It however takes about 3min to get the KVM1 server root prompt.
If I
ssh **wg**@KVM1
the KVM1 server prompt returns immediately.
Running
systemctl restart display-manager
on KVM1 hangs

The above configuration is running on OpenSuse-Leap-42.3 sinvce several years and I’ve never seen such an issue.
The problem might be related with the remote sudo command…
I ver much appreciate any hint where to search for the reason of this issue.
Thanks for reading.
