Subject: vnc: auto assian an id when calling change vnc qmp interface
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f7801c5ce42250bf1e84d21bceb1802cfe4485e8;p=qemu.git

vnc: auto assian an id when calling change vnc qmp interface

Only in this way, change vnc qmp interface can take effect,
because qemu_opts_find(&qemu_vnc_opts, id) will return NULL
in vnc_display_open(), It can't connect successfully vnc
server forever.
