commit 0124d57275a17544f796edb244a9406487efa29d Author: Radoslav Gerganov <[email protected]> Date: Tue Oct 31 11:22:46 2017 +0200 VMware: expose max vCPUs and max memory per ESX host Expose maximum vCPUs and maximum memory from single ESX host in the vCenter cluster. This will be used for implementing get_inventory() in the follow up patch. Partial-Bug: #1462957 Change-Id: I28e19d46a737ac253718c7c66837bd71b064b0b9 ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1462957 Title: VMware driver cannot report non-contiguous resources to the scheduler Status in OpenStack Compute (nova): Fix Released Bug description: A VMware hypervisor can have various types of non-contiguous resource. This includes: * CPUs and memory, assuming a cluster has more than 1 member. * Storage space, if a (VMware) host has more than 1 datastore. Focussing on the latter, if a host has 5 datastores, each with 50GB of free space, we currently report the largest contiguous free space to the hypervisor: 50GB. This means that the scheduler knows it can allocate an instance with a 50GB block device, but until the host stats are updated it will not allow subsequent instances to be scheduled there. We could alternatively report 250GB of free space, but would risk the scheduler repeatedly sending us a request for an instance with a 100GB block device, which we cannot fulfil. Without the ability to represent non-contiguous resources we are left choosing between 2 suboptimal choices.
