QEMU/KVM Attaching a Virtual NIC Directly to a Physical Interface

Posted on 2023-09-29 [Friday] by Jay Jay

Man, it took me a while to figure out how to do this! Over on Attaching a Virtual NIC Directly to a Physical Interface I figured out I could use this XML in Virtual Machine Manager (virt-manager) for my NIC device:

<interface type='direct'>
  <source dev='enp9s0' mode='bridge'/>
</interface>

That then gets expanded automatically to something like this:

<interface type="direct">
  <mac address="52:54:00:ce:5b:09"/>
  <source dev="enp9s0" mode="bridge"/>
  <target dev="macvtap4"/>
  <model type="rtl8139"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x10" slot="0x01" function="0x0"/>
</interface>

Update: ah, balls. This doesn’t completely work, because the guest can’t connect to the host, and vice versa, even though both the host and the guest can connect to the internet. This is a problem for another day. Maybe this or this will help?

Four pillars of virtualization

I’m reading Mastering KVM Virtualization and it says the four pillars of virtualization are:

CPU
memory

Circle that presses them

There’s a great quote from Carlos Castaneda in Journey to Ixtlan: “A warrior proceeds strategically. If one wants to stop our fellow men one must always be outside the circle that presses them. That way one can always direct the pressure.”

Good learners

Posted on 2023-09-28 [Thursday] by Jay Jay

I was reading about Neil Postman and found myself on the inquiry education page. It says that all good learners have:

Self-confidence in their learning ability
Pleasure in problem solving
A keen sense of relevance
Reliance on their own judgment over other people’s or society’s
No fear of being wrong
No haste in answering
Flexibility in point of view
Respect for facts, and the ability to distinguish between fact and opinion
No need for final answers to all questions, and comfort in not knowing an answer to difficult questions rather than settling for a simplistic answer

EarthBound

I read somewhere recently about EarthBound which is apparently a classic computer game. But I don’t recall ever having played it and I wasn’t able to find it on Steam.

Update: oh, I heard about it in The AI Revolution is Rotten to the Core

Fuck you ChatGPT

Posted on 2023-09-25 [Monday] by Jay Jay

Man. Today I can’t prove I’m human to ChatGPT because its captcha is too hard for me. I gave it like five or six goes. I’m a bit pissed off because I pay for access to ChatGPT and having it waste my time like this and then deny me access wasn’t what I sent my money for. Off I go…

Update: gonna try NoowAI, that looks interesting and like it might satisfy my usecases.
