Subject: Re: [Openstack] Making Image Launch faster in Openstack

Thanks Padraig, but is there any other way than using "squid". Like calling 
API's in glance or calling nova-compute API's or add something in glance code 
which triggers copy of vmdk to all compute nodes after image is uploaded.

CERN did some work on that:
