Regards, Lukas Straub -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1894818 Title: COLO's guest VNC client hang after failover Status in QEMU: New Bug description: Hello, After setting up COLO's primary and secondary VMs, I installed the vncserver and xrdp (apt install tightvncserver xrdp) insi= de the VM. I access the VM from another PC via VNC/RDP client, and everything is OK. Then, kill the primary VM and issue the failover commands. The expected result is that the VNC/RDP client can reconnect and resume automatically after failover. (I've confirmed the VNC/RDP client can reconnect automatically.) But in my test, the VNC client's screen hangs and cannot be recovered no longer. I need to restart VNC client by myself. BTW, it works well after killing SVM. Here is my QEMU networking device ``` -device virtio-net-pci,id=3De0,netdev=3Dhn0 \ -netdev tap,id=3Dhn0,br=3Dbr0,vhost=3Doff,helper=3D/usr/local/libexec/qem= u-bridge-helper \ ``` Thanks.
