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
