@flaxking said in Check my 2 min audio theory on Containers:

What you're talking about is one aspect of part of implementing DevOps that is often misinterpreted to mean the whole of it. And yes, it is stupid to call that DevOps. That's just Ops using different tools.

I see it as the opposite. Patrick's core DevOps...

"Thanks to the devopsdays conference, the idea of devops seems to live on. While talking with other people about it, I realize that it is difficult to frame it within the current IT landscape. At lot of the ideas are coming from different kinds of emerging technologies (T) and process management (P) approaches.

For me the two most important observations are:

there is a increase in feedback loops between business, all parts of the delivery process and operations thanks to this feedback loops we increase the quality and speed up the flow"

This is the core of DevOps, not well described, but pretty clearly about IT, not development. This is the core. Very, very loosely defined to the point of useless, sure.

Then things like DevOps talking dev itself is the extra, the tack on later. It's not "part of" devops, any more than it is of any operations. And just how operations doesn't cease to exist without developers, neither does DevOps.

I believe everything on that page is all meant to be within the context of companies doing development. But I agree, the core of DevOps is about Ops and Business practices. However, I firmly believe the name DevOps comes from Ops and Development working together, and thus the reason why discussions of DevOps implementation specifics centre around companies doing software development. Though just based on that page, I could see why someone could still take a different view. However, I consider The DevOps Handbook to be the definitive source, rather than notes on the initial discussions.

I think doing that makes DevOps a pointless, useless concept. Hopefully that's not what he intended. As an ops practice, it has tremendous value. As a merger of dev and ops, it's just bluster.

@scottalanmiller said in Delete All Snapshots on KVM with Virsh:

Is this a personal alias to Remove-VMSnapshot perhaps?

No I had that first but edited it incorrectly. Missed the VM in front.

But ya I thought vmcheckpoint was an alias but it's not.

Remove-VMSnapshot is correct.

So weird, they renamed it to checkpoint, but never changed the PS commands.

@stacksofplates I can imagine. Good luck!

@obsolesce that's annoying. . .

Edit: still annoying but doesn't Hyper-V have startup priority?

No it hasnt until I checked 6 months ago. Only way is build a delay schema by hand and assign delays to VM batch start them in layers

Hyper-V had startup priority since 2012... fully configurable... startup action and startup delay.

This is inaccurate. There is not a priority.

Hyper has only ever had this.

Okay, technically incorrect.... I'll give you that.

The point I was trying to make, was you can artificially set priority VM booting by adjusting the "startup delay" for each VM.

I've recently come across Restic and looks great:

Site:
https://github.com/restic/restic

Documentation:
https://restic.readthedocs.io/en/latest/

I haven't tried it yet, but it's on my list to try on my KVM server using Google's cloud as a test.

I’ve only tested it with backing up nextcloud user data and it’s been working great so far.

What are you backing up to?

I only tried an external hard drive and sftp to a Linux Server. I would like to try Backblaze.

I would like to check out Wasabi.

At first glance, https://wasabi.com/pricing/ looks like it could be a little cheaper than B2. Would definitely be cheaper if you need to download significant amounts often.

That was its selling point - a bit cheaper than even B2, but with full S3 compatibility.

Interesting read. I hope I never need to use it. Though, I would rather have it and not need it...

@phlipelder said in Hyper-V Server 2016 guest licensing question:

The guests on an OEM licensed host can be moved to another host whether it's licensed OEM, VL, or Retail so long as the destination host is licensed to receive those guests.

That makes no sense. That's not moving it, that's buying it twice. Very different things.

That's like "can I move my house from here to there"? People mean take the same house and shift its location. Not buy a second house in the new location and give up the old one.

@oksana

I doubt you will find the audience you are looking for at reddit, but good luck.

Go figure...CentOS-7 UEFI vm on Windows Server 2019 "Preview" w Hyper-V installs no problem!!!

@vhinzsanchez Containers are lighter and faster. And they are a type of virtual machine, Type-C virtualization. So things like performance and density alone are reasons that containers are popular.

You can restart the Hyper-V Virtual Machine Management service or the Windows Remote Management service and it should work.

@scottalanmiller said in KVM & Networking:

I have currently maybe 65 VMs on my KVM host, they each have their own IPs and are bridged. But there is a firewall and NAT sitting in front of all of it.

This is really how it is most cases regardless of hypervisor.

The only exception is in non-production when dealing with KVM + Wireless NIC... I haven't had time to see if I could get it to bridge somehow, so I'm stuck with NAT on my laptop. But, this is not an issue with servers, as they don't use wireless and this seems to be specific to wireless.

@emad-r said in Storage Setup for KVM:

@eddiejennings

keep your images and ISOs in the default location of /var/lib/libvirt/images/?

Yes I do, but I create 2 new folders there, iso and vm.

Fedora will be presented a 4 TB block device ?
Why dont you separe that a little, and have more fun. Block device I assume DAS, if no why dont you make the storage reliable and robust, and make it its own server, like another fedora or centos install, with RAID 10 and the simplest option to share is NFS, and this way you can have many KVMs and the migration feature will actually work, and you can do RAID on just /var, and you scan scale easily with KVM nodes + KVM nodes can be state file, think salt stack, and you can treat them as pure compute nodes.

Because @EddieJennings is talking about his home lab, which will consist of a single 1U server. That hadn't been mentioned in this thread.

Bah! Folks should be able to read my mind ;). There were some good ideas in this thread though.

What I decided on was giving enough space to / live comfortably, and gave everything else to /var.

@black3dynamite said in Determining resources for hypervisor:

Instead of using Fedora as a firewall VM, how about using VyOS?
https://wiki.vyos.net/wiki/User_Guide

I was thinking of that as well, since the OS for the ERLs.

EdgeOS and VyOS are cousins, both descended from Vyatta.

Fail2ban does nothing with key based access. It's denied before fail2ban even sees it.
