cab31c74	01/18/2013 01:30 pm	Christos Stavrakakis	Add warning message for backend without networks
2e1e6844	11/30/2012 02:47 pm	Christos Stavrakakis	Temporary fix for allocating archipelagos VMs
5dd9d123	11/02/2012 11:29 pm	Christos Stavrakakis	Introduce per-user allocation of VMs to backends Add BACKEND_PER_USER setting, a mapping from users to backends. This setting can by used in order to bypass the default backend allocation process, and allocate all the new VMs of a specific user to a specific Backend.
9cf4a3c0	10/03/2012 01:08 pm	Christos Stavrakakis	Refresh backends in locked mode
f96f60fd	09/28/2012 03:32 pm	Christos Stavrakakis	Move check for free IP to backend_allocator Filter out the backends that do no have a free IP in BackendAllocator instead of the default_allocator, in order to remove imports from synnefo in the allocation strategy.
adc46059	09/28/2012 12:19 pm	Christos Stavrakakis	Perform allocations in separate transactions Add ForUpdateManager to the Backend model, in order to guarantee exclusive order when allocating a VM. Use manual transactions when allocating Backend and public IP for a new VM, since these allocations need exclusive access (SELECT..FOR UPDATE)...
47d1d754	09/21/2012 11:23 am	Christos Stavrakakis	Add some logging to backend allocator
7fede91e	09/07/2012 05:36 pm	Christos Stavrakakis	Implement multiple public networks Implement multiple public networks in order to support: - different public networks per backend - non-consecutive IP ranges in each backend To support this, public networks are treated different from private ones. Namely, they are correlated with one backend (and so have...
cc7c0f44	07/23/2012 11:33 am	Christos Stavrakakis	Implement backend allocator and management command New module implementing instance allocation to one of the available backends. Allocation is performed based on memory and disk utilization. Statistics for each backend are stored in DB and updated periodically....
