Bug Description
After uploading a 5G image (cloud-
I'm aware that this is also dependent on hardware capabilities and may not constitute a bug - but possible uneccessary blocking occuring from one task to the next.
2 x Intel Core Duo E6550 @ 2.33GHz
2Gb RAM
Storage is local disk (SATA)
No swapping occurring.
Commands to reproduce:
$ cloud-publish-image -t image -K CentOS-
$ euca-describe-
Eventually returned this
IMAGE ami-00000011 images/
IMAGE ari-00000010 images/
IMAGE aki-0000000f images/
On my host (spec as described), nova-api running 99-100% on a single CPU (untarring image).
Concern is that no other users can use nova-api (and therefore Nova) until task is complete.
Is it the nova-api or nova-objectstore process that's blocking?
