You can do it that way, but I have both cables going into an HDMI switch and then to my single monitor. The switch has a button to select which input to use. It's important to get a switch that maintains a signal on the unselected input, otherwise the GPU might think it's disconnected and do something funny (especially if it's the Windows side), otherwise it works well. You also have to switch the keyboard and mouse unless you want to double up on those, but QEMU/KVM handles it fine with a Ctrl-Alt combo. However that's the easy part. The trickier part is to get Linux to completely ignore the VM's GPU so as not to interfere with the Windows drivers in the VM, which means creating a boot line to turn it off. That in turn depends on details of your motherboard and chipset. Alex Williamson has a great blog at: https://vfio.blogspot.co.uk/2015/05/vfio-gpu-how-to-series-part-1-hardware.html and there's a mailing list for all this at: https://www.redhat.com/mailman/listinfo/vfio-users However, once again: this is for people who want to run Windows VMs that use proprietary device drivers, e.g. for DirectX graphics. It's probably not necessary if you're just doing photo editing (video editing may be another story). poc _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org/message/KJCFAYTQSY7RFNX4HORGFFGW4WC4GUJA/
