#VIRTUALBOX SIERRA PARAVIRTUALIZATION FOR MAC OS X#

#VIRTUALBOX SIERRA PARAVIRTUALIZATION WINDOWS 7#

On windows 10 host, the guest runs normally (maybe a bit slow) but it boots and desktop is shown. Not to mention, all virtual disks i use are inmutable (to ensure identical tests). I had tested with a Windows 10 guest, running on a Windows 10 host and on a Linux host (or at least i had tried). If you migrating/moving VMs from Linux to Windows, I recommend to have default option, which makes automatic selection of best virtualization interface. So if you have upgraded VirtualBox to version 5 in Linux, just select kvm or default, start VM and check if it works correctly. These options are explained in detail under Section 10.4, вЂњ Paravirtualization providersвЂќ. and hyperv - recommended for Windows guests.

The minimal provider is mandatory for Mac OS X guests,.

The legacy option is chosen for VMs which were created with older VirtualBox versions and will pick a paravirtualization interface while starting the VM with VirtualBox 5.0 and newer.

This is the default option chosen while creating new VMs.

The option default, will pick an appropriate interface depending on the guest OS type while starting the VM.

Specifying none explicitly turns off exposing any paravirtualization interface.

This setting specifies which paravirtualization interface to provide to the guest operating system. paravirtprovider none|default|legacy|minimal|hyperv|kvm: Let's be more precise, because I had 4.3 migrated VMs, and those are 'legacy', also I was interested in what setting to use, if I copy VM from Linux to Windows or vice versa: Legacy: The legacy option is chosen for VMs which were created with older VirtualBox versions and will pick a paravirtualization interface while starting the VM with VirtualBox 5.0 and newer. None: Specifying none explicitly turns off exposing any paravirtualization interface.Дefault: The option default, will pick an appropriate interface depending on the guest OS type while starting the VM. The other options in the drop down do the following, as explained in the vboxmanage docs: This provider is recommended for Windows guests. VirtualBox's implementation currently supports paravirtualized clocks, APIC frequency reporting, guest debugging, guest crash reporting and relaxed timer checks.

Hyper-V: Presents a Microsoft Hyper-V hypervisor interface which is recognized by Windows 7 and newer operating systems. This provider is recommended for Linux guests. VirtualBox's implementation currently supports paravirtualized clocks and SMP spinlocks. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. This provider is mandatory for running any Mac OS Additionally, reports the TSC and APIC frequency to the guest operating system. Minimal: Announces the presence of a virtualized environment. The VirtualBox Manual, in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added):
