ravening opened a new pull request #5722: URL: https://github.com/apache/cloudstack/pull/5722
### Description Add a new parameter `unorderedfirstfitleastconsumed` for `vm.allocation.algorithm` which computes the suitable hosts list in parallel threads and does not care about priority but still ensures that other criterias are met Currently all vm allocation alogirhm computes the suitable host list sequentially and also the list for sutiable storage pools. If we have more than 200 hosts and storage pools then these checks will be done twice and takes really long time. If we dont care about the priority but still want all other criterias to be met then use the new allocation algorithm which computes the host list in parallel which is way faster. <!--- Describe your changes in DETAIL - And how has behaviour functionally changed. --> <!-- For new features, provide link to FS, dev ML discussion etc. --> <!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. --> <!-- When "Fixes: #<id>" is specified, the issue/PR will automatically be closed when this PR gets merged --> <!-- For addressing multiple issues/PRs, use multiple "Fixes: #<id>" --> <!-- Fixes: # --> <!--- ********************************************************************************* --> <!--- NOTE: AUTOMATATION USES THE DESCRIPTIONS TO SET LABELS AND PRODUCE DOCUMENTATION. --> <!--- PLEASE PUT AN 'X' in only **ONE** box --> <!--- ********************************************************************************* --> ### Types of changes - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] New feature (non-breaking change which adds functionality) - [ ] Bug fix (non-breaking change which fixes an issue) - [X] Enhancement (improves an existing feature and functionality) - [ ] Cleanup (Code refactoring and cleanup, that may add test cases) ### Feature/Enhancement Scale or Bug Severity #### Feature/Enhancement Scale - [X] Major - [ ] Minor #### Bug Severity - [ ] BLOCKER - [ ] Critical - [X] Major - [ ] Minor - [ ] Trivial ### Screenshots (if appropriate): ### How Has This Been Tested? <!-- Please describe in detail how you tested your changes. --> <!-- Include details of your testing environment, and the tests you ran to --> <!-- see how your change affects other areas of the code, etc. --> <!-- Please read the [CONTRIBUTING](https://github.com/apache/cloudstack/blob/main/CONTRIBUTING.md) document --> -- This is an automated message from the Apache Git Service.
