Yes, resource overcommitment is possible both in virtual machines and in containers.
Virtual Machines: A hypervisor can allocate more resources (CPU, memory) to virtual machines than physically available, assuming not all VMs will use the maximum at the same time. This increases hardware utilization efficiency but can lead to slowdowns or failures during sudden load spikes.
Containers: In orchestration systems (e.g., Kubernetes), resource limits and requests can be set. Overcommitment occurs when the total container requests exceed the physical resources of the node, allowing more containers to run but risking performance degradation under high load.
Thus, overcommitment is a balance between efficient resource use and the risk of reduced service quality.
