[libvirt] [PATCH 0/6] Support VNC password changes on running guests v2

[Daniel P. Berrange]

This patch introduces a new virDomainUpdateDeviceFlags() API to allow
the configuration of a device to be changed on the fly. It ports the
existing CDROM media change code in all drivers to use this new API
(keeps old support too). It then adds VNC password change support
in the QEMU driver using this new API
