#55 VNC on IPv6

[Farhan]

When you start a VNC service for a VM, it works fine under IPv4 but only uses port 5900 on IPv6. If two VMs are using VNC on IPv6 with the same port and you attempt to connect to them, both VMs will crash.
Manually specifying the port does not fix the issue, it appears that 5900 is hard-coded.

Hello,

This sounds like a VirtualBox bug if the VMs crash. Please open a ticket at VirtualBox.org

Sure! But I was having a bit of trouble finding out where you tell vboxsrv
what port to bind on.
