The actual number of virtual + functions available for passthrough depends on the number of interrupts vectors + required by each of them and on the hardware configuration of the host. Each + ESXi host has a limited number of interrupt vectors. When the host boots, devices + on the host such as storage controllers,​ physical network adapters, and USB + controllers consume a subset of the total number of vectors. Depending upon the + number of vectors these devices consume, the maximum number of potentially + supported VFs could be reduced. ​ \\ \\ **Correct Answer:** \\ 1024 \\ {{tag>​qq}} \\
