Has this ever been fixed on the QEMU or Spice side? Anyway, the QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now. If you stil

Hi James, The change in QEMU in 4.1 is that it's using a newer spice interface; Freddy is on our spice team and we chatted about whether to change QEMU but they thought it best to fix Spice to be more tolerant; so I'm happy to go with that recommendation. -- You received this bug notificati

Yes, I first replicated the issue by removing "max_outputs=1", then patched spice server, and the issue no longer happens. QEMU 4.1.0 still changed something. If I understand correctly, it's now in some circumstances saying there are 0 monitors, even though there's a graphic card? Fixing this in

James: Freedy proposed a fix for the bug I was looking at with a spice fix: https://lists.freedesktop.org/archives/spice-devel/2019-September/050859.html That's in the spice-server package. If you can check that it also fixes your bug that would be great. -- You received this bug notificatio

Sorry, my #8 was really long. All builds I've done were in clean chroots, so starting from scratch with just git source, with no interference from other builds. Also later in #8, I show that --disable-glusterfs doesn't work because some part of the build looks for the .so that was never built. L

hmm, disable-glusterfs *should* work around that; sometimes it's worth nuking the build directory and trying a fresh configure with these things. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1843151

P.S. Looks like I can use --disable-docs to hopefully get around the json parsing error, but that still doesn't help with the gluster error or that something is still looking the .so given --disable-glusterfs. -- You received this bug notification because you are a member of qemu- devel-ml, which

OK that's interesting - I've got another bug I've been following that's also fixed by (b). A bisect would still be interesting; but one place to start might be to try before and after commit be812c0 -- You received this bug notification because you are a member of qemu- devel-ml, which is subs

a) spice 0.14.2. Also spice-gtk 0.37, and spice-protocol 0.14.0. b) Swapping with "-device qxl-vga,max_outputs=1" does fix the problem. Swapping with "-device qxl-vga" still has the bug. c) Knowing b, would the bisect still help? If needed, sure, I will. -- You received this bug notification

Hi James, OK, thanks - some questions: a) What version of spice-server have you got on your host? b) Does swapping the '-vga qxl' for '-device qxl-vga,max_outputs=1' help? (try with and without the max_outputs=1) c) Are you able to do bisect builds to try and track down which commit

Finding a minimal case did shed some light on this. Using QEMU's native graphics window, this works fine: $ /usr/bin/qemu-system-x86_64 \ -m 1G \ -blockdev raw,node-name=install_iso,read-only=on,file.driver=file,file.filename=/mnt/losable/ISOs/archlinux-2019.09.01-x86_64.iso \ -device
