[Qemu-devel] [BUG] QEMU: Cannot VNC to a VM if a VNC is already opened to it

[Qemu-devel] [BUG] QEMU: Cannot VNC to a VM if a VNC is already opened to it

[Yaniv Kaul]

Using QEMU part of latest KVM (82-84, at least). A VNC session was established to a VM. Then, no one else can VNC to that VM.

Even:

1. If the shared desktop flag was set (not sure it is honored in the server)

2. If the VNC client was abruptly disconnected (there is no keep-alive between the client and the server, I reckon)

3. If the VNC client asked for read-only access.

I've opened https://bugzilla.redhat.com/show_bug.cgi?id=490344 and https://bugs.launchpad.net/qemu/+bug/312833 about this issue.

TIA,
Y.

This certainly used to be the behaviour, but just before QEMU 0.10.0
there was a patch merged to allow multiple concurrent VNC clients,
so I'm surprised if this is a still a problem with current release
or SVN checkout
