    Best way I've heard it described is that when you enable Hyper-V on a Windows Server, your Windows Server Core (or GUI) becomes the Linux equivalent of Dom 0

    And exactly like installing Xen onto Linux, Xen inserts itself as a "shim" under Linux and then reboots, booting into Xen instead of Linux. HyperV is identical, inserting itself as shim under Windows, rebooting and booting into HyperV instead of Windows.

    HyperV is modeled identically after Xen.

    I've already told Scott I would love to see one of the first major projects on the new NTG lab be to setup a ZT network.

    I like this idea. We could use the ZT Network for the NTG lab as a management network or something.

    I can see doing RAID 6 if you can afford the performance penalty.

    Which you would assume that you can if you can wait for a distant node to write as well.

    By distant, you mean local, as in the same rack?

    Yes, distant meaning outside of the chassis connected over a slow Ethernet link.

    @scottalanmiller I think of Snapshots as a quick point-in-time view... if something breaks, I can restore that snapshot in mere seconds, and I'm good to go.

    If I have to pull a full image from a backup, it could take minutes - hours to restore that backup...

    I would recommend looking at StarWind SA for example.
    That solution fits your requirements perfectly, it will also provide you with HA storage that will ensure the business continuity.
    As for support, they offer a single point of contact no matter what issue you face, plus the system will be shipped to your site fully preconfigured and pretested.

    OK, I guess I could try and test it if I have the time soon 😉

    Did you get a chance to test?

    @scottalanmiller Yeah... I know..

    It was just never bothered with. .. 😞

    I'm making a snapshot right now using NAUBackup of my VM's before running the upgrades. As ya never know if something will get broken.

    VMM: fixed an issue with Windows 10 guest kernel debugging over the network for Hyper-V paravirtualized VMs
    VMM: fixed a bug which prevented reading the saved state of the 'PATM' unit from VirtualBox 4.3.x (bug #14512)
    GUI: changed default OS type for Windows from Windows XP to Windows 7
    GUI: added another pre-defined guest screen resolution (bug #14384)
    GUI: fixed update check which was broken due to changing the location of the root certificates (bug #13096)
    GUI: fixed issues with synchronization of Caps lock / Num lock / Scroll lock on Windows hosts (bug #14302)
    GUI: don't crash during VM shutdown if 2D video acceleration and 3D support are enabled (Mac OS X hosts only)
    GUI: several seamless fixes for certain X11 window managers, also when used in multi-screen setups
    GUI: Log window size, position and cursor-position fixes
    Audio: fixed playing leftover/deprecated audio samples
    Audio: fixed playing audio after suspending the host (5.0 regression; Linux hosts using the ALSA backend)
    Audio: fixed playing short audio samples which were chopped off formerly
    Audio: fixed distortions on OS X when the sample rate of the guest stream and host device don't match
    Storage: fixed raw disk access and flat VMDK image access which would be always opened readonly (5.0.2 regression; bugs #14425, #14461)
    Storage: fixed initial encryption of VDI images after they were compacted (bug #14496)
    VGA: fix for certain graphics modes (bug #14516)
    NAT: don't freeze while the VM is paused if the network attachment mode is changed from/to NAT with activated port forwarding
    OVF: fixed duplicate USB controller entries in exported OVA/OVF (bug #14462)
    Shared Folders: fixed a path separator issue (bug #14434)
    Drag and drop: fixed crashes on OS X hosts when doing host-to-guest transfers
    VBoxManage: another attempt to not deny changing the network adapter type at VM runtime (5.0 regression; bug #14308)
    VBoxManage: fixed broken guestcontrol <VM-Name> list command (5.0 regression)
    VBoxManage: fixed broken Guest Control stdout/stderr output (5.0 regression)
    Mac OS X hosts: fixed remaining problems with activated SMAP (Broadwell and later; bug #14412)
    Mac OS X hosts: fixed broken 3D support (5.0.2 regression; bug #14476)
    Linux hosts: Linux 4.2 fix
    Linux hosts: don't crash on older Linux distributions if the DBus service isn't running (bug #14543)

    Windows hosts: fix for Windows 10 build 10525 and later (bug #14502)
    Windows hosts: fixed network adapter enumeration on Windows 10 (bug #14437)
    Windows hosts: prevent intermittent host network disconnects during VM start/shutdown with bridged networking (bug #14500)
    Windows Additions: fixed the call to the memory allocation function (bug #14415)
    Linux Additions: be more forgiving if the compilation of the vboxvideo module fails (bug #14547)

    Also, don't take this as my saying that closed source is better - I'm not. I'm just saying that anyone who isn't already familiar with this situation needs to be aware that just because something is open source does in no way imply that anyone has ever done an audit, let along a security audit of the code.

    No, but you are implying that open source is equal or worse, but it is not. It is better (or equal.) It literally has no downsides compared to closed source (for the end users, obviously what is bad for the customers might be good for the vendor) but does require customers (but not every customer) to leverage to have it still be beneficial for all (one enterprise doing an audit and checking or improving code helps everyone). The same code made open or closed will always be better or equal to the same code closed source.

    You are completely correct that no one should think that the nature of a license for code visibility would mean that it is magic and that audits are automatic - but I've never heard of anyone implying or believing such a thing. I think we were all assuming that no one thought that open sourcing code was doing anything like that.

    But we also have the vast majority of enterprise open source software being audited all the time. So in one way, we have to be aware of basics like source licensing does not imply an audit. At the same time we have to be understanding that major companies certainly do audit core code, especially security code, regularly and that there is a level of auditing going on on enterprise open source that exists nowhere else.

    Exactly - two 6 TB HDD's may be a lot less expensive, but the performance compared to SSD would be insanely different.

    How many HDDs would you need to reach your IOPS requirements?

    I've never monitored them.

    The work is being done by Dom0, not the VM.

    And with the resources being statically assigned I can't imagine that there is much of a hit to the performance of the VM's them self.

    The question from me is, Is the effected version of VMware 6 an effected version because of a patch they released or an RTM problem?

    Isn't every version patched at some level? There isn't just one version.

    NFSv4 is only for security, typically you want to avoid this in a production virtualization environment. You would want to be on NFSv3 for performance reasons.
