The QEMU project is currently moving 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 the bug state to "Incomplete" now.
If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".
If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:
1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:
https://gitlab.com/qemu-project/qemu/-/issues
and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.
2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).
Thank you and sorry for the inconvenience.

Title:
COLO's guest VNC client hang after failover
Status in QEMU:
Incomplete
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
