[Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
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 -serial vc:640x480'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1257352 Title: kvm hangs occasionally when switching out of the qemu console To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1257352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
Interestingly, after i lock the qemu console up with the xdo script, the screen is always locked in ctrl-alt-2, that is, the monitor, not the vm display, hitting ctrl-alt-1 never returns it to the vm display, but if i continue the xdo script running, it sometimes does return to the vm display, where you can see memtest continuing to run.

Re: [Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
That's surprising. Can you test it with upstream qemu? ( git clone git://git.qemu.org/qemu.git cd qemu ./configure --target-list=x86_64-softmmu make cd x86_64-softmmu ./qemu-system-x86_64 --enable-kvm qemu-args ) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1257352 Title: kvm hangs occasionally when switching out of the qemu console To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1257352/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
I never saw the issue with saucy. Downgrading to 1.5.0+dfsg-3ubuntu5.1 certainly appears to have resolved the issue for me, so it's looking like a regression introduced by 1.6.0+dfsg-2ubuntu4. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1257352 Title: kvm hangs occasionally when switching out of the qemu console To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1257352/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1257352] Re: kvm hangs occasionally when switching out of the qemu console
Thanks, James. I suspect this is due to the arm64-user-static patchset i added. As mjt has pointed out it has a lot of cruft in it.
