Public bug reported:
1. User try to boot a new vm by click the button "+ Launch Instance" in
dashboard web->project->compute->instances.
2. But the button "+ Launch Instance" is disabled and shows "quota exceeded".
3. Then user go to dashboard web->project->compute->overview perspective, but
find Instances,VCPU and RAM haven't exceed
the quotas. In this case, it's shows like below:
Instances
Used 8 of 10
VCPUs
Used 18 of 20
RAM
Used 512MB of 50.0GB
This will confuse the user, is there anything incorrect?
root cause:
I think one of the root cause is that the current project have another work,
such as rebuilding vm, which obtail some quotas and mark
the 'reserved' fields(nova->quota_usages table) to a none zero value .
So I select * from nova.quota_usages where project_id = 'current project id',
and find thati in the row 'cores' , the 'reserved' = 2. Because of this, the
VCPU is actually Used 10 of 10.
Excepted result:
The 'reserved' quota should also be taken as an used quota ,and so in dashboard
web->project->compute->overview perspectiv, it should shows as below:
VCPUs
Used 20 of 20.
