Hardware Requirements To set up vMA, you must have an ESXi host. Because vMA runs a 64-bit Linux guest operating system, the ESXi host on which it runs must support 64-bit virtual machines. The ESXi host must have one of the following CPUs: ■ AMD Opteron, rev E or later ■ Intel processors with EM64T support with VT enabled. Opteron 64‑bit processors earlier than rev E, and Intel processors that have EM64T support but do not have VT support enabled, do not support a 64‑bit guest operating system. For detailed hardware requirements, see the Hardware Compatibility List on the VMware Web site. By default, vMA uses one virtual processor, and requires 3GB of storage space for the vMA virtual disk. The recommended memory for vMA is 600MB.
