Dell Considers Bundling Virtualization on Mobos 138

Posted by Zonk from the wave-of-the-future dept.
castrox writes "Ars Technica is reporting that Dell may be considering bundling virtualization on some of their motherboards. No more dual boot or VMs inside the running OS? 'Any way you slice it, though, putting the hypervisor in a chunk of flash and letting it handle loading the OS is the way forward, especially for servers and probably even for enterprise desktops. Boot times, power consumption, security, and flexibility are all reasons to do this ... The big question is: which hypervisor will Dell bundle with its machines? Vance suggests hypervisors from XenSource and VMware as two options, but I think that VMware is the most likely candidate since it seems to be the x86 virtualization solution of choice for the moment. However, if Dell doesn't try too hard to lock it down, this system could easily be modified in an aftermarket fashion to include almost any hypervisor that could fit on the flash chip.'"

      The only reason I've ever called a manufacturer's tech support line in years has been to get an RMA. And it's generally just irritating when they insist on taking me through their little script before they'll admit defeat and return the piece of junk.

        A few tips on calling Dell tech support if you are a competent engineer who diagnosed the problem before reporting it.

        1. For a home PC the techs are so incompetent that it's easier to just lie about the nature of the problem. I.e. If your hard drive is on the fritz, making rattly sounds and loosing data just say "The drive is completely dead. When I connect it the BIOS doesn't even admit that it's there".

        2. Gold support is better than economy or even silver, but not for the reasons on dell.com. It's better because they connect you to the most competent support guys almost immediately when you call the gold support line. Competent engineers know when they are speaking to an equal and will dispatch the required parts immediately. They also send out "just-in-case parts".

        3. Call late at night if your warranty allows it. The brightest tech support guys in Texas know that the graveyard shift is the best time to work. Less traffic on the commute, more pay and more time available for none work related tasks. Your shortest and most fruitful calls will be at 2:00 AM.

        4. Don't be afraid to hang up. I once had an external tape drive (PV 110T) that was bursting tapes whenever I initiated a backup. The tech support guy insisted that I must reboot the server so I could see if the drive shows up in the BIOS before he could go any further. I hung up, called back latter and got a brighter support guy who dispatched a replacement drive in around 5 minutes.

        • #2 is the most important, I find. Dell's non-Gold support is worthless. On the other hand, their Gold support is pretty darn good. Needless to say, every system we buy (which are mostly laptops) are bought with the Gold support and Complete-Care.

Compromise a guest and you haven't compromised the machine. In fact, one thing you might run on the host is an Intrusion Detection System that monitors the guests and shuts down any that might go rogue. Better yet, you could "freeze" the rogue by ceasing to schedule CPU cycles to i

          Run your user account inside a guest, and at least the base OS won't get compromised, and you won't need to reinstall. Run your browser and/or email inside a guest inside your account, and you won't have to worry about virii or web nasties compromising your precious code and data. It's all about damage limitation/confinement.

There's certainly precedent for this, and we're sure to see a lot more of this in the future. Hopefully the PC market is competitive enough that Dell won't be restricting their own hypervisor

    They are doing this for DRM.

    Their Hypervisor will enforce DRM, so even linux can't override it.

    They'll make it so all device drivers must be signed to go into the
    Hypervisor which will be the only thing with any I/O privs that aren't
    virtualized.

    They'll make it so new hardware has closed interfaces and can only be
    supported by a driver at the Hypervisor level.

    Any drivers in any OS level won't be able to circumvent the DRM, since
    they'll just THINK they are talking to hardware, but will get virtual
    hardware instead - and the Hypervisor won't let it read any protected
    content through the virtual I/O, it will blank it out (e.g. all zero
    bytes from the "soundcard") or something similar.

    The drivers designed for the Hypervisor won't work in any higher level,
    since they'll need to do a crypographic handshake with the hardware to
    verify it is "real" and the hardware will also monitor bus activity so
    it'll know if any extraneous activity is occur (as it would if it was
    being virtualized).

    Everything will have a standard interface to the O/S, so Linux will still
    run but be very limited and slowed down - since only Windows will be
    allowed "preferred" access to hardware, other O/S will be deliberately
    crippled.

    They'll say you can still run Linux.

    Hardware manufacturers won't release specs, they'll say use the Hypervisor
    and you can still use Linux.

    You'll still need to buy Windows to use any hardware - Linux won't even
    boot on the raw hardware.

    MS doesn't care if Linux isn't killed - the above allows them lock in - no
    windows - your PC won't boot - since nothing but the Hypervisor will know
    how to talk to the IDE card, etc.

    What about manufacturers that want to support open interfaces, etc?
    Microsoft will deny them a key which they will need to talk to the
    Hypervisor - and the Hypervisor will refuse to talk to them.

    Support anything other than solely the Hypervisor and you can't use the
    Hypervisor. No Windows - lose too many sales.

    And they can say other O/S's are still allowed.

    They'll just not be able to give you freedom to use your hardware as you
    see fit (DRM, need to pay more to get software to unlock other features
    on your hardware), only Windows will run well, and you need a Windows
    license and Hypervisor for every PC or else it is unbootable.

      On the contrary; Dell has been driving companies like Broadcom and Adaptec to open up and offer open source drivers. AFAIK the only reason we have the tg3 driver is because Dell told Broadcom to provide Linux drivers.

    This frightens me on so many levels that it is difficult to know where to start. Unless that hypervisor is burned into a non-rewritable form of storage (e.g. ROM), it will be subverted.

    As it has been demonstrated at Black Hat by the illustrious Ms. Rutowska, (as well as being fairly obvious to anyone familiar with hypervisors) a hypervisor is below the OS and can be impervious to the OS's probing, but it still lies between the OS and the hardware.

    Properly implemented, this could be a very good thing. With no disrespect intended toward Dell, I suspect that the first several implementations (at least) will leave the resulting systems vulnerable to subversion, and this subversion would be difficult, at best, to detect.

    This is an interesting concept, and it could be used for "good", but as the saying goes "the devil is in the details". The idea is good, it is the potential implementation that worries me.

    It's easy to see how moving more stuff from the disk to flash is "slicker" and can make things load a little bit quicker (but seriously: how much? I doubt transferring hypervisors, kernels, or boot managers (e.g. grub) from disk is a major factor in boot times). But what's so special about hypervisors? Forget making this "solution" so specific. Just build a few dozen megabytes of disk-like (bootable) flash into the board, and let the user decide if they just want to use it for a hypervisor, or move a whole bunch more stuff into there in an effort to try to get their modern machine boot as fast as an Amiga.

    The one thing that it occurs to me that such an answer would really help with, is working around a certain (dumb) Linux limitation. Booting off EVMS is tricky (or at least it was, last time I looked). Move your boot off-disk, then you can EVMS your whole disk.

    And what's this about "security?" The article doesn't explain why it mentions security, and that's not a surprise, because there's no reason it would be more secure. As other have pointed out, "security" is obviously being used as a codeword for something very, very different (i.e. having the machine serve someone else's interest (e.g. MPAA) at the expense of the user's interest).
