Hi, At the summit there was a session about this. Please also see https://review.openstack.org/85792 Thanks Gary From: Rakesh Sinha <rakesh.sinha at gslab.com<mailto:rakesh.sinha at gslab.com>> Date: Monday, May 26, 2014 4:35 PM To: Pádraig Brady <P at draigbrady.com<mailto:P at draigbrady.com>> Cc: "openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>" <openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>> 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: http://coarasa.dyndns.org/?p=162<https://urldefense.proofpoint.com/v1/url?u=http://coarasa.dyndns.org/?p%3D162&k=oIvRg1%2BdGAgOoM1BIlLLqw%3D%3D%0A&r=eH0pxTUZo8NPZyF6hgoMQu%2BfDtysg45MkPhCZFxPEq8%3D%0A&m=uk5UeNLCDtH4%2Bx1kXlhPNZ8GLyRTbsDUSKlzpqsezDY%3D%0A&s=b76ce857ca16d18b390c9fd45d1f6282dbf0a49dfbc79bfdea724b1f94837e09> thanks, Pádraig. -------------- next part -------------- An HTML attachment was scrubbed...
