> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.6.0
> Reporter: Harikrishna Patnala
> Assignee: Harikrishna Patnala
> Fix For: Future
>
>
> There are some VM deployment failures happening when multiple VMs are
> deployed at a time, failures mainly due to NetworkModel code that iterates
> over all the vlans in the pod. This causes each deployVM thread to hold the
> global lock on Network longer and cause delays. This delay in turn causes
> more threads to choose same host and fail since capacity is not available on
> that host.
> Following are some changes required to be done to reduce delays during VM
> deployments which in turn causes some vm deployment failures when multiple
> VMs are launched at a time.
> - In Planner, remove the clusters that do not contain a host with matching
> service offering tag. This will save some iterations over clusters that dont
> have matching tagged host
> - In NetworkModel, do not query the vlans for the pod within the loop. Also
> optimized the logic to query the ip/ipv6
> - In DeploymentPlanningManagerImpl, do not process the affinity group if the
> plan has hostId provided.
