[Users] Failed to Start VM (Run Once) due to internal spice channel error

When trying to run a first time (Run Once) VM install, the vm session fails to start. When we look into the libvirtd.log on the host, we find the following error: virDomainGraphicsDefParseXML:6566 : internal error unknown spice channel name ain in the lines right above message, contained in the xmlDESC we find the following snippet: <channel type="spicevmc"> <target name="com.redhat.spice.0" type="virtio"/> </channel> <graphics autoport="yes" keymap="en-us" listen="0" passwd="*****" passwdValidTo="1970-01-01T00:00:01" port="-1" tlsPort="-1" type="spice"> <channel mode="secure" name="ain"/> <channel mode="secure" name="nputs"/> <channel mode="secure" name="ursor"/> <channel mode="secure" name="layback"/> <channel mode="secure" name="ecord"/> <channel mode="secure" name="isplay"/> <channel mode="secure" name="sbredir"/> <channel mode="secure" name="martcard"/> </graphics> It looks to us that the xml may be malformed due to the seemingly first character missing in the channel names. Does this make any sense to anyone?
