This commit adds vmpooler inspection of configuration issues to host
selection. Specifically, configIssue is checked, which should allow an
issue like quickstats not being reported to be identified even when the
alarm will not trigger. Without this change a host will continue to be
used if quickstats are not reported when alarms are not triggered
because of this condition, which results in a single host being the
target for all deploys and migrations, overloading the host and causing
its VMs to have degraded performance.
Previously the vsphere provider assumed that there was one and only one
datacenter (DC) in the vsphere instance. However this is simply not true for
many vSphere installations. This commit:
- Adds the ability to define a vSphere datacenter at the Pool or Provider level
whereby the Pool setting takes precedence
- If no datacenter is specified the default behaviour of picking the first DC
in the vSphere instance
- Updated all tests for the new setting
- Update the vmpooler configuration file example with relevant setting name
and expected behaviour
- Fixed a bug in the rvmomi_helper whereby if no DC was found it would return
all DCs. This is opposite behaviour of the real RBVMOMI library as it returns
nil
Previously the vSphere provider did not implement any of the required methods
from the base class. This commit modifies the vSphere provider so that in
can properly implement the following methods:
- name
- vms_in_pool
- get_vm_host
- find_least_used_compatible_host
- migrate_vm_to_host
- get_vm
- create_vm
- destroy_vm
- vm_ready?
- vm_exists?
- create_disk
- create_snapshot
- revert_snapshot
This commit also includes changes to syntax for rubocop violations.
Previously there were no spec tests to document the behaviour of the
vsphere_helper. This commit adds the behavioural spec tests in prepration of
the refactoring work as part of POOLER-70, the connection pooling work in
POOLER-52 and various bugs found in vsphere_helper while these spec tests were
being created.
