e90273829b Add ioctls to control the X2APIC capability exposed by the virtual machine to 
the guest.

At the moment this simply sets the state in the 'vcpu' instance but there is
no code that acts upon these settings.

177fd53318 Add sysctls to display the total and free amount of hard-wired mem for VMs 
# sysctl hw.vmm
   hw.vmm.mem_free: 2145386496
   hw.vmm.mem_total: 2145386496

1ff856dbd7 Allow the 'bhyve' process to control whether or not the virtual machine sees an 
ioapic.

90d4b48f60 API to map an apic id to the vcpu. 
At the moment this is a simple mapping because the numerical values are
identical.

32c96bc813 There is no need to explicitly specify the CR4_VMXE bit when writing to guest 
CR4. This bit is specific to the Intel VTX and removing it makes the library
more portable to AMD/SVM.

In the Intel VTX implementation, the hypervisor will ensure that this bit is
always set. See vmx_fix_cr4() for details.

cd942e0f25 MSI-x interrupt support for PCI pass-thru devices. 
Includes instruction emulation for memory r/w access. This
opens the door for io-apic, local apic, hpet timer, and
legacy device emulation.

366f60834f Import of bhyve hypervisor and utilities, part 1. 
vmm.ko - kernel module for VT-x, VT-d and hypervisor control
  bhyve  - user-space sequencer and i/o emulation
  vmmctl - dump of hypervisor register state
  libvmm - front-end to vmm.ko chardev interface

bhyve was designed and implemented by Neel Natu.

Thanks to the following folk from NetApp who helped to make this available:
