ASRock Z90 Extreme.

Has 2 built in NICs. The intel 1g and the Broadcom 2.5g.

Trying to use the Broadcom here, though my Ethernet is only 1g house wide, so I could try the intel if that seems like it could help..

Ok. I’ll check it out.

Let’s say it is exhausted… what will get me more bandwidth? CPU or mobo..?

Only other pci-e card in at the moment is 16 line HBA seems to be basically 2 cards sandwiched on one board)…

This may also help, my HBA is there:

sorry this took so long.. you know, life. trying that command altogether, I get this response: -bash: acpidump: command not found

trying just egrep "DMAR|IVRS" (in case they are two commands) seems to hang the terminal session.

I tried following a guide to enable PICe passthrough and get this. One important thing, there is no discrete GPU at the moment, I'm trying to pass through an HBA..

I’ve also had this idea in the back of my mind…. Curious what people suggest…

I hate Trump so very deeply. There is nothing redeeming about him or what he’s done to this country.

That being said, at least this quote you shared (the article is paywalled) is very obviously Turd saying that Biden’s vote totals beat Obama’s, from their respective elections, in swing states. But did not beat Obama’s numbers in non-swing states.

He’s trying to imply that this is proof that there was election rigging in those swing states and that’s the reason Biden’s totals exceed Obama’s previous totals.

I don’t think it makes those of us who ducking hate Turd look like we have a strong case when we willfully misread what a reasonable person can tell Turd was trying to say and then say it’s evidence that Turd is demented.

Trump IS a demented racist fraud. I hope he chokes to death on this KFC while I’m typing this…. But let’s make a stronger case with actually demented statements and not refuse to understand what’s in plain sight here.

This is in proxmox?

How can I tell if my mobo even supports it?

Ok. So they are different?

How do I tell which motherboards support IOMMU?

I can’t find it as a filter or search option on any websites…?

Well, that's at least part of my problem. I have no idea what it would be called so it's hard to google. I guess the underlying technology is all 'IOMMU', but each motherboard manufacture and Intel and AMD all have other names for it...

I'm trying to pass an HBA through to a VM for a NAS.

Look. I don’t support vaporizing Gazans and I also feel rather impotent to do anything about it. I also think things are broken and our county needs some major systemic changes to give power back to the people.

And I support the ‘uncommitted’ vote in the primary to send a clear message to Biden.

But don’t kid yourself with this ‘both sides are the same’ stuff.

Biden will, at the very, very least, try to reduce suffering where he can. And that may be pathetically little.

But this is the other side that WILL come to power if you (and I mean you) don’t vote for Biden this fall:

Trump breaks silence on Israel's military campaign in Gaza: 'Finish the problem'

A communication disruption can mean only one thing: INVASION!

Fucking finally.

Battery pack accepts incoming USB-C charging. You can apparently daisy chain chargers together with any USB-C battery pack that can output the right power.

I just got an R36S for ~$36 shipped from Alibaba. It’s awesome out of the box, but you can tweak. It’s incredible what it can do at that price.

To son proof it, just grab an image of the SD card before he starts mucking with it. Easy to flash back to a known-good starting point.

You can even back up his customized version when he has it mostly working before he mucks it up again.

They didn’t. It’s just smaller now

Not sci-fi, but The Princess Bride.

I continue pooping in the next stall over.

First google link that looked reasonable. I have not followed this. But I bet it will work.

I’m noodling a plan to do something similar because my synology NAS is running out of space.

But my plan was to have bare metal run proxmox and have xpenology in a proxmox-managed VM.

I’m very much an amateur tinkerer, here, but it’s been my impression that proxmox is a vastly more powerful VM manager than xpenology.

Even in your current setup I’m surprised you don’t have proxmox managing your fedora instance.

I’ve played with proxmox only a little so far, but it seems like it’s purpose-built to be that base-level layer managing everything running on top of it.

Even things like being able to log into each system right in the browser without messing with VNC or some other virtual desktop tool is just baked in.

….but now I wonder if I got the wrong end of the stick here..?

Hoping people who know better than me will weigh in!
