No, that is not valid. WTF is even “mainstream”?

main·stream /ˈmānˌstrēm/ noun

I know how it is defined. But how are you claiming which ones are mainstream. Because there is only subjective evidence to support any of your wild ass bullshit claim.

Mint is Mainstream to many. It is old and nasty and not something I would ever use.

Ubuntu is a steaming pile of shit that only has popularity among "developers" because it was "popular" as a desktop OS.

Okay ass.

You know what my intention is and was when using the term Mainstream.

So get off your horse and onto the dildo, cause you need to sit and spin for a while.

Completely unwarranted reply from you, because the use and intention of "mainstream" is useless no matter how you try to swing it... HOWEVER, I LMAO so hard at this.

Maybe if it is studded? For that extra oomph?

Definitely studded. Only way to go.

Mangolassi.it - Always go for a flaming laugh!🙂

So following on from the Other thread.

Looks like i'm heading to the Install KVM, setup a Linux VM and use that to manage the KVM server from that.

@Pete-S said in Typical virtualization host server config?:

We've calculated guesstimated 8GB RAM and 50 GB SSD storage per VM on average.

How did you come up with your guesstimate? Do you have some workloads in production right now that you'd be virtualizing with whatever host your configure and buy?

Yes, actually we have the hardware now but it hasn't been configured completely yet. We are still figuring things out.

The workloads are running on physical servers (Windows) and it's latency that is our primary concern, not capacity. We are moving the applications to linux and making them multi-tenant and horizontally scalable at the same time. So that's why we are guesstimating based on the config of the physical servers.

@FATeknollogee the install itself has been covered too many times to mention 🙂 Maybe if he runs into a specific issue and solves it, that would be a good thing to share

Conversely, I over-allocated vCPUs across several VMs (ESXi) when I was new to type 1 hypervisors and ran into performance issues associated with high CPU ready times. After scaling down, performance improved dramatically.

@Dashrender said in Why I Feel KVM Is the Easiest HyperVisor to Learn the Basics On:

The question is - why is the quality so bad? Isn't the process supposed to catch bad quality?

Their process is consider the windows insider group (extreme power users) to be a good enough replacement for proper QE teams, and writing automated build tests.

Right, the new process isn't to catch bad things, it's actually to see bad things as "not all that bad." Presumably because a shift from viewing their products as being for business to being for entertainment. Remember when Windows 95 was a key tool for businesses, but by Windows 98 they had made sure to put a "for entertainment purposes only" label on the product to make sure no one confused it with something that was intended for business use?

I feel like that's where they are now. At least internally, no one is really thinking of this as a business tool.

@scottalanmiller said in KVM with Cockpit on Fedora 29 Network Type Options Greyed Out:

When building a new VM using Cockpit's web interface to KVM on Fedora 29, the Network Type option leaves most options like Bridge to LAN, Generic ethernet connections, and Direct attachment greyed out. Anyone know why?

Did you try with network manager? Any missing package?

Too bad KVM is not available on Mac then I can move from using Virtualbox.

@obsolesce said in Fedora 28 KVM Cockpit Doesn't Show All VMs:

Everyone is always waiting for someone else to report bugs and issues, that's why they take so long to get fixed. Not as bad with FOSS, but a big reason with MS for example.

But I don't know that it is a bug. It's reasonable that it might be, but it's just one possibility.

Allowing an SSH connection to the managementVM from the Internet

I have not tried this approach yet, and it appears more risky than the Screen Connect approach, since SSH to that VM would be open to the Internet. Unless I'm missing some benefit to this approach, I'll not be using it.

Use a strong key, lock to your IP. Very safe. Add Fail2Ban, of course.

Or add Salt and open/close based on need so it doesn't stay open.

Fail2ban doesn't work with keys.

But it would work normally with people attacking using non-keys, would it not? Or am I missing something about what it would do?

Why would you not require keys? Not making them mandatory defeats the purpose of using them.

I think he means - if a hacker is trying to use a password on a system setup to only allow keys - the fail2ban will block those users, or won't it?

No. It's dropped before fail2ban even sees it.

Oh, makes sense. There is no "attempt" like with a password, it is "already blocked."

@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.

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