Does anyone have any ideas .. it sounds like a bug to me.
To begin with I'd look in the logs (usually in /var/log) and e.g. use
'dmesg' to see if there's anything intersting. If USB communication
is somehow being broken for the kernel I'd expect that there would be
something which mentions it.
Nothing interesting in the logs
Since the user hasn't mentioned anything about USB passthrough, and the
normal USB emulation is very reliable in my experience, I'd look for
something else.
We're not even quite sure if the keyboard is using the USB subsystem -
isn't the default PS/2-based? I know that there are USB tablet (mouse)
and keyboard devices, but they aren't the only ones and libvirt, if I
remember correctly, defaults to the non-USB components.
In all the setups it seems Qemu is defaulting to PS/2 but initially
both the keyboard and mouse work fine.
Crucially, there's *no* connection between VMs and hosts regarding
keyboard and mouse input. It doesn't matter what technology you use on
the host.
Since the issue only happens after some idle time, I suspect a
screensaver to become active. They typically catch keyboard input, but
no mouse input.
I will check for a screensaver, not sure if one is loaded in any of
the 3 distros but it's a distinct possibility. Never thought of that.
Thanks
