Guests wont start with 15 pcie-root-port devices

2021-11-12 Thread Brian Rak
In 6.1, a guest with 15 empty pcie-root-port devices will not boot properly - it just hangs on "Guest has not initialized the display (yet).".  As soon as I remove the last pcie-root-port, the guest begins starting up normally.  My qemu command line: /usr/libexec/qemu-kvm -name guest=xxx,debug

We ran into this as well, using qemu 2.11.0. We're not using the "-k en-us" command line flag, and we're using noVNC as a client (which supports the QEMUExtendedKeyEvent encoding) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https

Public bug reported: Since 2.9 / 07e95cd529af345fdeea230913f68eff5b925bb6 , whenever the VNC websocket server finds an error with the incoming connection request, it just closes the socket with no further information. This makes figuring out what's wrong with the request nearly impossible. I wou

We've been considering switching over to using qemu's built in websockets support (to avoid the overhead of needing websockify running). We've been seeing very poor performance after the switch (it takes the console 4-5 seconds to update after pressing a key). So far, I haven't been able to f
