Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU (version 3.0)? Which window manager were you using here?

Firstly, what works: A single VM instance, running Windows. Although, I am keeping this (GTK) window focused. What really fails: If I have two running VM's, WIndows XP and Windows Vista: 1. I press Ctrl-Alt-G to get the focus. 2. That works first time. 3. Then I press Ctrl-Alt-G again. 4. Then Alt-Tab to the other machine (switching from XP to Vista, or back.) 5. Then press Ctrl-Alt-G to gain focus: - Problem is that now the Ctrl-Alt-G, although showing in the title bar, only grabs the mouse, but NOT the keyboard. That is to say, whilst in Ctrl-Alt-G mode the second time, pressing Alt-Tab jumps back to the other VM! Pressing Alt-F4 quits!!!!!!!!!!!!! Regardless of whether Ctrl-Alt-G mode or not! But only when running two VM's. Thanks Misha To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1485180/+subscriptions
