Hi Jay, I think what you're looking for is called "overcommit": http://docs.openstack.org/trunk/openstack-ops/content/overcommit.html OpenStack will allow you to allocate more memory to instances than actually exists on the host. --Alex On Tue, May 21, 2013 at 7:47 PM, Jay Kumbhani wrote: >

If you go for four different types of backend as you propose, and each has an associated config file, then it would be possible to use a single SQL database to hold all the information, or a single writeable LDAP to hold it all, with pointers to the same database in each config file. Alternativ

OK, I think it makes sense. If we keep roles and role assignments in the same place, we don't have the ability to do more complex assignments. So the four backends would then be: Domains Identity (Users, groups) Assignments (could also be called mapping) Projects (Includes roles) Assuming t

Yes, nova-scheduler has lots of filters to check if nova-compute node fit the requirement of the instance you wanna launch. Like availability-zone filter, RAM filter, cpu core filter, etc. If all the compute node failed to pass those filters, it raise this exception. Regards Lei On Tue, May 21,
