bhyve on SmartOS

Introduction

The following options that aren't in the kvm brand should work:

  • com1, com2
    • Can be set to tty-like devices or socket,/some/path.
    • If both are unset, com1 defaults to /dev/zconsole and com2 defaults to /tmp/vm.ttyb.
  • bootrom
    • Should be set to /usr/share/bhyve/BHYVE_UEFI.fd or /usr/share/bhyve/BHYVE_UEFI_CSM.fd
  • Defaults to /usr/share/bhyve/BHYVE_UEFI_CSM.fd
