> VMware uses a folder in machine where management server is running to mount
> secondary storage. This is a bootstrap phase to start system vm, because
> unlike KVM, Xenserver, management server cannot directly access VMWare ESXI
> host to download systemvm template from secondary storage to primary storage.
> The secondary storage is usually managed by SSVM that uses root account to
> download templates. However, management server is using account 'cloud' to
> manipulate templates after secondary storage is mounted. After admin
> registers new systemvm template in CS as a normal upgrade procedure, the old
> SSVM will download the template using account root, but management server
> will create new SSVM from the new template using account 'cloud'. Then a
> permission denied error will raise.
> Prior to 4.4, CS used to handle this by running 'chmod -R' to the folder to
> which secondary storage is mounted every time management server mounts
> secondary storage. Unfortunately, this method is slow because we are trying
> to give permissions to the entire folder. So in 4.4, we stopped automatically
> providing the permissions and asked admin to manually run 'chmod -R' to the
> folder 'templates' on secondary storage, after registering new systemvm
> template.
> We can avoid this manual admin step by only providing permissions for the
> /templates folder instead of the entire folder. This way we will avoid the
> snapshots folder which could be very large in upgrade setups.
