In what scenario is live VM migration particularly risky for virtualized environments?

Live VM migration is particularly risky in virtualized environments when there is a lack of secure deprovisioning. This is because when virtual machines (VMs) are migrated while the deprovisioning of resources has not been effectively managed, sensitive data may remain accessible within the original host environment or the underlying storage. If appropriate secure wiping procedures are not followed, remnants of data could be exploited by unauthorized users, leading to data breaches or loss of confidentiality.

Moreover, a successful migration should involve ensuring that any data no longer needed on the source node is adequately destroyed, thereby eliminating the risk of exposure. Effective deprovisioning processes also ensure that licenses, rights, or configurations tied to the original environment are handled properly, protecting the integrity of the operational environment during and after migration.

In contrast, scenarios such as excessive VM replication, privilege escalation, or data remnants are not inherently tied to the migration process itself and do not emphasize the critical nature of securely managing the lifecycle of data and resources as strongly as the risks posed by inadequate deprovisioning.
