15616	Linux 5.1 aborts when using a KVM switch (Qt monitor hotplug)	Christopher Juckins		"When using a KVM (keyboard/video/mouse) switch with VirtualBox 5.1 running on Linux Centos7, the guest VMs abort when I switch from my host computer to my second computer.  

Here is my setup:

Host computer Centos7 version 7.2.1511 with kernel 3.10.0-327.22.2.el7.x86_64.  I installed VirtualBox  VirtualBox-5.1-5.1.0_108711_el7-1.x86_64.rpm this morning.  

I can start up my two guest VMs (also running Centos7) without issues.  

When I toggle my KVM switch from my host Linux computer to my other computer (Windows 10) and then go back to my host Linux computer, both of my guest VMs are gone from my screen.  When I restart the main VirtualBox  program GUI, both of my guest VMs show ""Aborted"".

I downgraded back to Virtual Box 5.0 (VirtualBox-5.0-5.0.24_108355_el7-1.x86_64.rpm) and the KVM abort problem disappears.

If I can provide any more information just let me know.

I am trying to attach my VBox log file as well.

Thank you for your help.
