Hello oVirt Development team
We had some more questions as we continue working on REST APIs. Kindly
help us answer the same.
What is the expiry of generated access_token?
*Description: *We have observed that the output of
*“/ovirt-engine/sso/oauth/token” *contains a field *“exp”* which points
to the date when the access_token is going to expire. In our case, we have
seen this value to be 8 days later. However, the access_token gets expired
within an hour. We would like to understand exactly what is the lifetime of
this access_token? What we are seeing is something unexpected? Is this
value configurable by users?
How to retrieve the ‘creation_status’ of the snapshot through REST API?
*Description: *We see there is a way to get it as part of query snapshot
API viz /ovirt-engine/api/vms/<vm_id>/snapshots/<snapshot_id> where the
response contains detailed information of snapshot, along with the field
*"snapshot_status":
"ok". *Just wanted to check if there is another API explicitly devoted to
getting the creation status so that we can poll it periodically to know the
status?
At least in CURL, we see there is some URL to fetch the creation status
like this /ovirt-engine/api/<vm_id>/snapshots/<snapshot_id>
/creation_status/<WHAT_IS_THIS_ID?>"
*Q.* How to call a DELETE snapshot API with ‘async’ operation as ‘false’?
*Description: *The documentation for DELETE snapshot API mentions that
the DELETE operation can be invoked synchronously or asynchronously based
on the value of the parameter ‘async’. I wanted to perform DELETE operation
synchronously, so tried providing this parameter in the body as
“<async>false<async>”, still it was doing the operation asynchronously.
Please advise on the correct usage of it.
Thanks
Suchitra

*Subject: *Image Transfer mechanism queries/API support
Hello oVirt Development team
We had a conversation with Pavan Chavva for supporting RHV. He had
suggested to contact you with queries related to oVirt APIs we plan to use.
We have following queries:
1. While downloading a snapshot disk, can we identify allocated
extents and download only those using oVirt API? We are able to download
the disk using the Image Transfer API mechanism.
However, this method downloads the entire disk including the non-allocated
extents, which is a performance overhead. If this functionality does not
exist at this point will it be available in near future?
2. Is there an alternate method to transfer a snapshot to and from
RHV storage? Are there other methods such as NFS share where we can
download snapshot image to and from RHV storage?
Thanks
