[Qemu-devel] [Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
Mon, 13 Mar 2017 20:13:05 -0000
It seems the issue is sdl related to change in sdl window size. If I
started qemu and set the monitor (and serial & parallel) to the same VC
size, it works much better. Instead of hangs on a 2-3 switches, it may
hang after rapid switch of more than 10 times. Btw, it can hang in any
windows, i.e. display, monitor or serial/parallel.
So the workaround to ease this is, something like '-monitor vc:640x480

kvm hangs occasionally when switching out of the qemu console
Status in QEMU:
Status in qemu package in Ubuntu:
To recreate (although this does *NOT* fail most of the time alas):
1) press "ctrl-alt-2" to switch to the qemu console.
2) type say "sendkey ctrl-alt-f1"
3) press "ctrl-alt-1".
Expected outcome: Switch to tty1 in the VM.
Actual outcome: No switch to tty1 in the VM. and qemu console
unresponsive to any keyboard input.
Rather a vague problem description I'm afraid but this has happened to me 3
times recently. No crash and no excessive CPU is observed.
I'll grab an strace when it happens again and attach...
