  • It’s solving a real problem in a niche case. Someone called it gimmicky, but it’s actually just a good tool currently produced by an unknown quantity. Hopefully it’ll be sorted or someone else takes up the reigns and creates an alternative that works perfectly for all my different isos.

    For the average home punter maybe even up to home lab enthusiast, probably not saving much time. For me it’s on my keyring and I use it to reload proxmox hosts, Nutanix hosts, individual Ubuntu vms running ROS Noetic and not to mention reimaging for test devices. Probably a thrice weekly thing.

    So yeah, cumulatively it’s saving me a lot of time and just in trivialising a process.

    If this was a spanner I’d just go Sidchrome or kingchrome instead of my Stanley. But it’s a bit niche so I don’t know what else allows for such simple multi iso boot. Always open to options.


  • Don’t waste time on pandering to proof of ability when actions speak louder than words. The release of your research is personally something I’m looking forward to regardless of your history or experience. I will interpret your research and evaluation with my own bias and sceptical stance. I’d rather question you afterwards if your article left questions unanswered or unclear.

    Jumping the gun now and questioning you before we start just wastes both our time.

    Good luck with your research!




  • I think you probably don’t realise you hate standards and certifications. No IT person wants yet another system generating more calls and complexity. but here is iso, or a cyber insurance policy, or NIST, or acsc asking minimums with checklists and a cyber review answering them with controls.

    Crazy that there’s so little understanding about why it’s there, that you just think it’s the “IT guy” wanting those.


  • Sr-iov works already though? That’s not needed for this. The motherboard presents the pci bus to the guest regardless of what’s plugged in. Works fine.

    This is when you want many guests to have shared graphics by partitioning a gpu. So the host still retains it and presents the graphics card to guests. You need to partition the ram up equally though, so useful only in VDI generally where you want a RTX A6000 like card to split to 10 guests each with 8gb of ram, and they share the gpu, but keep their individual video ram. Economy of scale can work out in graphics or maybe ML situations. Not so useful at home since you’ll probably have a Rtx 3080 with like 10-12gb of ram, and at most you wouldn’t want to split it below 8gb for modern games and partitions need to be equally sized. For 10g two = 2x5gb which would be a poor experience probably. Lots of frame stutters as it switches stuff between ram to video ram.

    Hope that helps. Unless this technology unlocks better partitions it’s more about opening to vdi and machine learning in a full open source context like proxmox rather than just the driver being locked behind hyperv vmware and citrix hypervisor/xen and a big yearly license. Maybe it still needs that yearly license.


  • This is possible now, but in xen or vmware you need to buy a nvidia license to unlock this feature. You can trial it for a minute in a lab but you can’t give 4 guests each 2gb of vram on your graphics card without Nvidia specialist proprietary driver on both the host and the guest.

    For vdi where you can buy 48gb rtx a6000 graphics cards, with architects (for example) each user getting each about 8gb each, you can 10 guests concurrently per card. Which at a few hundred architects scales better than buying many $5000 dollar workstations that struggle with WFH.

    For a home user, maybe being able to split for your two kids on a standard rtx 3070 with what like 8gb might be OK? Probably not though.

    Right now I have a hacky way that isn’t really supported in nvidia to split graphics cards to two guest vms but it’s neither license compatible or what I’d call “production ready”. I’d like proxmox to be able to handle this out of the box because it’s already in the kernel.

    I’ve no idea what this means with licensing though. The yearly license cost to allow you to use your driver is actually stupidly expensive. The Rtx A series cards are already dumb money.

    Either way it’s a good thing, but probably not much news for the average enthusiast






  • The root cause of this issue that they identify, is 100% the kind of AI that they’ll build for this situation.

    Old mate wants to use it to keep people on their best behaviour. The kind of subjective wording that whatever he doesn’t like, is the exact reason people lie in court.

    Power to that thought process through systemising it, legitimising it, is exactly part of the problem.

    What’s that American who said lies about the eating cats then justifying it by saying “I’d lie if it got the American public to wake up”. Let me get the quote…

    https://www.mediaite.com/news/remarkable-confession-jd-vance-absolutely-floors-observers-with-comment-that-hes-been-creating-stories-about-migrant-pet-eating/

    If I have to create stories so that the American media actually pays attention to the suffering of the American people, then that’s what I’m going to do.

    Yep. It’s not infallible, it’s intentional. Intent goes into the creation of systems and implementations. These are the kind of people that want these systems. They’re justified in their own minds.

    So to close the loop you linked that article and it’s point was:

    More than half of wrongful convictions can be traced to witnesses who lied

    Don’t give them reason for more ways to do so. Don’t give them legitimacy. That’s deterministic. It’s intent. It’s not failed if it worked. Your opinion on a system which is failed or fallible is not the same as the Oracle hocho who wants to be God.

    They’re not sharing your values, morals, ethics or compassion.






  • Other then legacy and uefi does it have a CSM compatibility support mode? An option to enable usb initialisation before bios? Eg wait for usb initialisation?

    Some “boot faster” options kind of reorder boot initialisation to a point where it’s not holding the system back.

    Though I’m really running out of suggestions… I can imagine you’re pretty frustrated. I know my Dell laptop was a pain to get the right settings to get usb to boot and the stupid 100db beep to silent on boot interruption.



  • I suggest a few more things:

    Try a different brand usb. Different motherboards sometimes don’t support some usb brands. In fact, a Lenovo server I rebuilt refused to boot off certain usbs.

    Some motherboards don’t initialise boot off some usb ports. Sometimes the additional ports are on another controller and initialise too slow.

    Just try a straight working Ubuntu live boot usb to remove any ventoy from equation. Ubuntu has real signed uefi (and no shim) granted by Microsoft. I think that’s how it works, uefi is a mess.

    Try to start isolating all the different factors, and there could be more. It doesn’t necessarily mean anything definitive if it works on another machine.
