linux networking – network interfaces are deleted after issuing a virsh shutdown on VM

I tried to instantiate a VM using virt-install command with few interfaces as needed. The exact command is as follows:

virt-install 
    --name VM 
    --noautoconsole 
    --input keyboard 
    --os-variant rhel7.0 
    --memory 8192 
    --vcpus 4 
    --boot hd 
    --sound none 
    --disk "vol=default,boot_order=1,bus=sata" 
    --disk sda6 
    --network bridge=eth0

Immediately after this, I tried to attach an interface using virsh attach-interface command as follows:

virsh attach-interface --domain VM --type direct --source eth1 --model virtio

I was happy with the XML configuration of the VM as the interfaces showed up correctly.

$ virsh domiflist VM
Interface  Type       Source     Model       MAC
-------------------------------------------------------
vnet16     bridge     eth0       virtio      52:54:00:e9:d5:4c
macvtap0   direct     eth1       virtio      52:54:00:70:be:74

But when a virsh shutdown was issued and later the VM was started, somehow the interface which was attached did not show up in the XML. I was left with only the eth0 interface. Not sure how/why the eth1 vanished.

$ virsh domiflist VM
Interface  Type       Source     Model       MAC
-------------------------------------------------------
vnet16     bridge     eth0       virtio      52:54:00:e9:d5:4c

Please let me know what can be done to avoid this situation such that the interfaces are preserved as-is like before the VM was shutdown.

Bitcoin vs Dogecoin – Difference at network level

With all the Dogecoin hype , mainstream media has been comparing Doge with established cryptos like Bitcoin.

Trying to understand the difference at the technical level –

  1. It comes up that Bitcoin network has better security. Is that due to the hashrate ? If more miners start switching to Doge, wouldn’t that solve the problem ?

  2. Doge code is also almost same as Bitcoin.

Ignoring the coin supply factor, where Doge can continue creating 5 billion coins per year, is there any other reason Bitcoin network is superior ? Does it boil down to simply which network gets more adoption ?

finder – How does macOS get “pretty” hostnames in Network view?

In computer networking, “hostnames” are limited to alphanumeric characters, with dashes (no whitespace or other punctuation).

However, when I open the “Network” in Finder…

Finder - Locations - Network

I can see some devices (usually macOS) show up with spaces, punctuation, and UTF-8 characters in the name:

Network devices. MacBook has spaces

Ultimately, I’m looking to have the Raspberry Pi on my network show up with a pretty name. However, in my searching on how to do this, I’m finding I’m not even clear on how macOS gets these pretty names to show up. Searching for this yields too many results of articles explaining to people how to change the hostname of their mac, which I don’t need help with.

On my Raspberry Pi, I can run hostnamectl and set the “pretty” name, but that doesn’t seem to affect anything.

Anyone know how this is achieved?

mining hardware – How can I mine a block, in C#, on a new Testnet network where no other miners exist?

I want to demonstrate how to use NBitcoin or the most simple C# function to collect transactions for use in a block, and then sign that block, and submit it into the Bitcoin-QT network client on the RPC port?

I want to demonstrate how this is done on low powered devices.

soft fork – Is there network split risk for Taproot activation with two releases (Bitcoin Core and Bitcoin Taproot)?

Every soft fork or consensus change involves a (very small) non-zero risk of a network split. That risk is considerably lower for a soft fork than say a hard fork (where all nodes need to upgrade). That’s why soft forks aren’t attempted every month or year. All you can do is minimize that risk.

Aaron lays out some scenarios that are theoretically possible. Any incompatibility between “Bitcoin Core” and “Bitcoin Taproot” during the Speedy Trial deployment is in my view highly unlikely. If Speedy Trial fails to activate and we reach November 2022 (please note 2022 not 2021) without miners activating then we are in a similar scenario to the UASF in 2017 where it depends on what the economic majority is running. I can’t predict what the economic majority would be running in November 2022 but I highly suspect the delaying of Taproot activation would be at the top of everyone’s minds.

You do have to weigh up these risks of a network split with miners deliberately blocking Taproot activation potentially forever. If we were to say no more UASFs ever again because we don’t want to take any network split risk that would be handing miners a permanent veto to block the activations of soft forks that have community consensus. So you have to weigh up the risk of the latter which would be just as concerning (if not more concerning) to people.

So in summary these are subtle trade-offs. A number of developers have worked hard to minimize the risk of a network split. But it doesn’t get to zero unless you literally never try a soft fork again. And that would mean that Bitcoin would never seriously improve again.

lightning network – Why do people who try to push an important but obscure project not realize that it has to be made SIMPLE?

I’ve been massively interested in the Lightning Network since I first heard of it. Yet every single time I try to actually use it, I come back frustrated and angry, concluding that there’s not even a proper client for Windows at all. (Which is insanity.)

And even if there were, the entire setup is absurdly complex. It should be like a “turnkey” solution that you simply fire up and then start using, without having to learn about these million different concepts.

Why do developers/evangelists of things that they (allegedly) want people to use not realize that they have to make it simple and non-user-hostile for there to be any adoption to speak of?

As it currently is, Lightning Network might not even exist at all to me. Which is very sad and frustrating, since I want to use it already.
