KVM Specifications

> KVM Specifications

> | Memory foot print – Similar to any embedded virtualization layer, KVM is very thin and takes very less resources.

> | PCI pass-through – Sometimes, the hardware might not be virtualized; therefore, the hardware must be redirected into the virtual machine (VM) for its direct control. This feature is called PCI pass-through, and there are several flavors for it: 1-1 memory mapping, para-virtual PCI, and hardware support using VT-d.

> For information about the KVM bits, and to make the PCI devices pass through, refer to the user documents of the respective operating systems.

> | Host Bus Adapters (HBA) – Nytro WarpDrive cards and HBAs connecting the back-end must be a pass-through so that the VM can have direct mapping and control of the Nytro WarpDrive cards and the HBAs in the server.

> | PCI resources – The PCI resources cannot be shared across the VMs, that is, the WarpDrives and HBAs cannot be shared across the VMs.

> | Virtual machine management (VMM) – VMM does not need external tools running in the privileged VMs or the Hypervisor to manage the VMs.
