EVC can refer to different things depending on the context. Here are some possible meanings of EVC based on the search results:

• Enhanced vMotion Compatibility: EVC is a feature in VMware that allows virtual machines to be migrated between different generations of CPUs.

• Ethernet Virtual Connection: EVC is a data link layer bridging architecture that supports Ethernet services. It is defined by the Metro-Ethernet Forum (MEF) as an association between two or more user network interfaces that identifies a point-to-point or multipoint-to-multipoint path within the service provider network.

• Electronic Verification Code: EVC is a 10-digit alphanumeric code that is sent to a registered mobile number to verify an item electronically. It is used by the Income Tax Department in India to validate e-filing of tax returns.

• EVC mode of a virtual machine: In VMware, the EVC mode of a virtual machine determines the CPU and graphics features that a host must have in order for the virtual machine to migrate to that host and power on. The EVC mode of a virtual machine is independent from the EVC mode that you configure for the cluster in which the virtual machine runs. The EVC mode of a virtual machine is determined when the virtual machine powers on. If the EVC mode of a running virtual machine or the entire EVC cluster is raised, the virtual machine does not change its EVC mode until it is powered off and powered on again.

In summary, EVC can refer to Enhanced vMotion Compatibility in VMware, Ethernet Virtual Connection in networking, Electronic Verification Code in tax filing, or EVC mode of a virtual machine in VMware.
