Hi, It seems that issue is the following : Since these hosts and Guests are now hosted in a RHEV Cluster, RHEV-M deals only with transient domains . (.xml config files are downloaded from RHEV-M when Guest is started.) So, from my understanding, only way to add my channel device is to use a VDSM hook. Hope to find some examples of vdsm hooks. Thanks for your help.
