Hi,
I also tested some emulated nic devices and virtio network devices (in
the attachment).
The VNC client's screen cannot be recovered while using all virtio
network devices and the emulated e1000e nic.
Thanks.
Regards,
Derek

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) inside
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=e0,netdev=hn0 \
-netdev
tap,id=hn0,br=br0,vhost=off,helper=/usr/local/libexec/qemu-bridge-helper \
```
Thanks.
Regards,
Derek
