Looking at the comments, it seems to me that this was an issue in VTE that got fixed. Is there still anything left to do for upstream QEMU here? ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868116 Title: QEMU monitor no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1868116/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As Vte-upstream long term would want to get rid of this implementation style Christian Persch provided a qemu patch [1]. That is too much UI for me to really have an in-depth opinion, but I can say that it builds and input works fine with it. I suggested on [2] to send it to qemu-devel, but in case that doesn't happen it might be great if Gerd Hoffmann and Cole Robinson could take a look at it.

>From IRC: [16:10] cpaelzer, @vte, we should get 0.60.1 for focal, 0.59.91 is a rc1 for 0.60, we are lacking behind merging the stable version from Debian but it's on our backlog (kenvandine was look at that one), the .1 is part of GNOME 3.36.1 which we plan to get before release (I would understand if you would like to backport a patch to help testing rather than waiting though) >From VTE Bug: The standard Ubuntu freeze doesn't apply to GNOME packages. Usually Ubuntu aims to ship latest GNOME x.1. VTE is part of GNOME, VTE 0.60.0 is part of GNOME 3.36.0, VTE 0.60.1 belongs to GNOME 3.36.1 etc. Accordingly, 0.60.0 -> 0.60.1 contains important bugfixes only, no new features. In this particular case, 0.60.1 will bring a trivial shell script fix (quite important for non-VTE users), and hopefully this one. It would be outright ridiculous for an LTS distro to ship an unstable VTE. So, the only reasonable thing for Ubuntu 20.04 is to ship VTE 0.60.1. Anyway, this is not the right place to discuss it.

I'm not sure how many of you are tracking the Vte bug [1] so here a summary of the latest insight from there. - Short term it seems that new behavior will be reverted in Vte 0.60.1. - Long term the Vte devs might want to deprecate no-pty use cases or at least better understand why apps use it that way.

[Bug 1868116] Re: QEMU monitor no longer works
I'm not really a UI guy, so I was checking what I might have lost by disabling VTE and found the very old [1]. That list of features really seems to make disabling VTE not an real option: "It's also screen reader accessible, supports copy/paste, proper scrolling and most of the other features you would expect from a terminal widget." After seeing that Cole authored the "drop PTY" [3] patch I have subscribed him here as well. I have tried to answer and ask a few questions on the VTE issue [2] to get it make progress, but it would really benefit getting the attention of Gerhard and Cole (or anyone else who feels the UI-power).

For a bit of reverse-confirmation of the findings so far. If I build qemu without VTE, like (configure) GTK support yes (3.24.14) VTE support no It works, due to the fallback implemented by [1][2]. But obviously without all the VTE features, I'd prefer a more fine grained fix than disabling VTE :-) [1]: https://git.qemu.org/?p=qemu.git;a=commit;h=f8c223f69ac58488ea830597281b7ddd33037c4c [2]: https://git.qemu.org/?p=qemu.git;a=commit;h=bbbf9bfb9c27e389340cf50a11c22fa46c572150 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868116 Title: QEMU monitor no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1868116/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for this investigation so far! We've opened an upstream VTE issue at https://gitlab.gnome.org/GNOME/vte/issues/222 . We'd appreciate if QEMU developers joined us there. Apparently QEMU uses the "commit" signal in a way that it was not meant to be used, and thus it's unclear what the best solution would be. ** Bug watch added: gitlab.gnome.org/GNOME/vte/issues #222 https://gitlab.gnome.org/GNOME/vte/issues/222 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868116 Title: QEMU monitor no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1868116/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

commit 55e5d53676960feb5dc11400ecdc7c9d7c4ab13e (refs/bisect/bad) Author: Christian Persch Date: Sun Nov 17 22:15:38 2019 +0100 lib: Add missing files commit 7888602c3a980eee093313b2c0f949c756668070 (refs/bisect/skip-7888602c3a980eee093313b2c0f949c756668070) Author: Christian Persch Date: Sun Nov 17 21:58:09 2019 +0100 lib: Rework child exit and EOF handling When the child process exits, we used to immediately unset the PTY, which causes us to miss data written by the child but not yet read by vte. Instead, only store the child exit status, and defer emitting the 'child-exited' signal until after all the pending data has been read and processed. Similarly, rework how EOF is processed. Instead of immediately queuing the emission of the 'eof' signal, only take note of the EOF, and process it after all pending data has processed. There also was a bug in that we took the first occurence of G_IO_HUP in Terminal::pty_io_read() to stop reading more data. Instead, only take a pure G_IO_HUP without G_IO_IN as EOF, or if reading data from the PTY returns the EIO error. This also fixes the bug where a(ny) partial character(s) not yet fully decoded by the UTF-8 and ICU decoder would not show in the output; this now correctly flushes the decoder, which inserts either a replacement character (for the UTF-8 decoder) or the character(s) in the ICU decoder internal state (most likely also a replacement character). https://bugzilla.gnome.org/show_bug.cgi?id=777686 commit 9e4fbae2cabcd937ac4d1a984ba844d24b44b83f (refs/bisect/skip-9e4fbae2cabcd937ac4d1a984ba844d24b44b83f) Author: Christian Persch Date: Sun Nov 17 21:58:09 2019 +0100 lib: Use ICU for legacy charset support Instead of converting the whole chunk of input from the input charset to UTF-8 in one go, we need a decoder that consumes the input one byte at a time. Since the iconv API is not particularly suited to this (or, really, any) task, switch to using ICU for this. Add functions to get the list of supported legacy charsets, and to check whether a particular string is a supported charset.

I started to consider bisecting: #1 check if v4.2.0 from upstream exposes the behavior => yes it does #2 check if v4.0.0 from upstream does not expose the behavior => No, v4.0.0 is as broken as th v4.2.0 build Hmm, this used the same build options and the same build environment. Might it again be an issue with the BIOS or the libraries? Copying the binaries into an Eoan environment makes them work.

[Bug 1868116] Re: QEMU monitor no longer works
Hi Leonardo,
I first ran something in libvirt as usual, and I got monitor access through
libvirt as usual.
For example:
$ virsh qemu-monitor-command focal3 --pretty '{"execute":"query-block"}'
Then I started a most basic qemu to get the usual UI.
$ qemu-system-x86_64 -enable-kvm --drive
media=cdrom,file=http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/mini.iso
I can switch to the monitor there
default grab is CTRL+ALT
monitor on SHIFT+2
I was only once able to switch to the monitor, and then I failed to
enter something just as you describe it. Setting to confirmed, but this
needs a deeper look.
