Are you Licensed for VMware FT (Fault Tolerence).

It's only available in vSphere Standard, Enterprise and Enterprise Plus in vSphere 5.x.

insufficient resources to satisfy configured failover level for vsphere ha

suggests VMware HA does not have suffucient resources on other hosts.

You can change this cluster feature, and disable admission control.

The operation would violate the configured failover level of the vSphere HA cluster. Either change the admission control policy to reserve fewer resources for failover or add more hosts to the cluster.
Check the CPU and Memory reservations of the virtual machine in question.  As a virtual machine starts up, slot calculation will be affected and fewer slots will be available when a machine with high reservation values is started.
