Hi,
Currently I am using the latest libvirt API listAllDomains() to probe for domains.
I may need to fall back to older API for old libvirt server such as: listDefinedDomains()
and lookupByName()
instead of listAllDomains().
Is there any disadvantage to using listAllDomains instead of listAllDomains
or its the same results via different API?
I guess you meant "disadvantage to using listDefinedDomains and
listDomainIDs instead of listAllDomains". And yes there is, you have
to call two functions, one for collecting domains that are shut off
and one for those that are running. For those that are running, you
only get IDs and you have to iterate over them. The process is not
atomic, so if in the meantime the domain changes status, it can appear
twice (once for each list) or not at all.
Does that answer your question.
Thank you,
Shahar.
