[libvirt-users] domain reinitalization detection

Hello I'm trying to find out how to detect if domain was destroyed and brought up between two time moments, let's call it reads. So far the best approach I could find is to compare domain ID from previous and current read. And this is my first question : is that reliable solution ? Or do you know any better ? And related question is how to resolve virDomainPtr into domain ID ? The only verified way of getting domain ID I know is to memorize it's UUID, then call virConnectListDomains , then iterate over all returned domain IDs and resolve each one's pointer using virDomainLookupByID , then get UUID by virDomainGetUUIDString get domain ID of matching UUID's . It seems too complex and I expect noticeable performance overhead, so looking for something lighter. I'm trying to get current domain ID using API function : char * virDomainGetMetadata (virDomainPtr domain, int type, const char * uri, unsigned int flags) I'm not sure it's relevant function, since domain ID is contained not in metadata subsection but in opening <domain> markup. In fact I wasn't even able to get any data using that function call since I don't know how to construct valid URI. Do you know any doc or examples explaining that ? Any help appreciated Krzysztof -------------------------------------------------------------- Intel Research and Development Ireland Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
