move all listxxx interface from HostDao to managers(ResourceManager, SecondaryStorageVmManager etc) with decent name using SearchCriteria2
or direct call SearchCriteria2 on demand
Changes:
To make sure migration does not attempt to pick a host that has running VMs more than the max guest VM's limit:
- Changed manual migration to call host allocators to return a list of hosts suitable for migration. Host allocators check for the max guest VM limit.
- Earlier we returned hosts with enough capacity but now Host Allocators make other checks along with capacity. So the list of hosts returned are hosts that have enough capacity AND satisfy all other conditions like host tags, max guests limit etc. Or in other words Allocators dont return the hosts that dont satisfy all conditions even if they have capacity.
-Therefore, now we mark the list of hosts returned for manual migration as 'suitable' hosts instead of 'hasenoughCapacity' in the HostResponse.
- HA migration already calls allocators, so no change is needed there.
Changes:
- Changed host allocators/planner to use cpu.overprovisioning.factor
- Removed following: while adding a new host, we were setting the total_cpu in op_host_capacity to be actual_cpu * cpu.overprovisioning.factor. Now we set it to actual_cpu.
- ListCapacities response now calculates the total CPU as actual * cpu.overprovisioning.factor (This change does not add anything new - listCapacities was pulling total CPU from op_host_capacity DB earlier which had the cpu.overprovisioning.factor applied already. Now we need to apply it over the DB entry.)
- HostResponse has a new field: 'cpuWithOverprovisioning' that returns the cpu after applying the cpu.overprovisioning.factor
- Db Upgrade 222 to 224 now updates the total_cpu in op_host_capacity to be the actual_cpu for each Routing host.
