Title:
VMware: Same image should not be transferred more than one time on
concurrent spawn operations
Status in OpenStack Compute (Nova):
Opinion
Bug description:
On concurrent spawn operations, the VMware driver transfers the same image
into different temporary directories before getting into the cache: the same
bits might be downloaded 20 times if 20 spawn operations happen at the same
time for a given image (before being cached).
The goal here is to use a lock to only transfer one time the bits of the
image.
