Subject Xen - Deploying servers from a template
Date Tue, 28 Apr 2015 11:13:16 GMT
Hi All,

Quick question with regards to xenserver and deploying a cloudstack
instance from a template stored within secondary storage.

In this case it is secondary storage using NFS and deploying to local disk
on the xenserver. (cloudstack 4.3, Xen 6.0.1)

I believe this script is used to pull down the template:
/opt/cloud/bin/copy_vhd_from_secondarystorage.sh

I'm seeing a big variation when deploying 3 servers, for example. 2 of the
servers might start very quickly and one may take longer.

Is there any caching of the template taking place on the xen host its self?
If a host has previously deployed a template, and is then asked to deploy a
new instance using the template, will it have to go back to secondary
storage again or can it use a local cache of the vhd file?

Many thanks in advance for any responses.

Cheers!
