>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Management Server
>    Affects Versions: 4.1.0
>         Environment: RHES64 as in OEL64. Install from RPM built from latest GIT on OEL64.
> 2 or more KVM hypervisors with local storage in one cluster that has one primary NFS
storage pool.

> ACS402 works with no issues when tested in exactly the setup where ACS41 fails.
> Identical configuration (the same setup program is used for testing both versions).
> In ACS410 startVM fails if and only if the advanceStart: log line picks a poolID that
is not valid.
> E.g., the poolID reported in this logline appears random across a large number of tests.
> If a poolID that can not be reached by the host selected for deployment, the startVM
fails.
> This is blocking upgrade from 4.0 to 4.1 since there is no  reliable way to start VMs
that have been deployed. If a deployed VM fails to start, giving the startVM command multiple
times, will eventually make the VM start.
> The more hosts there are, the less likely it is a startVM will succeed. It is less likely
that the poolID is correct.
> The below log portion conveys how the VM has a "correct" Deployment Destination reported
and the advanceStart reports a poolID that is different and since the selected hypervisor
can not reach the poolID the startVM fails.
> The bug never triggers if there is only one KVM with local storage since the poolId can
not be wrong, there is just one (and the NFS pool is always valid).
