Optional I<graphicsuri> overrides connection parameters used for automatically
reconnecting a graphical clients at the end of migration. If omitted, libvirt
will compute the parameters based on target host IP address. In case the
client does not have a direct access to the network virtualization hosts are
connected to and needs to connect through a proxy, I<graphicsuri> may be used
to specify the address the client should connect to. The URI is formed as
follows:
protocol://hostname[:port]/[?parameters]
