@scottalanmiller this was actually always the case. MS ran into boot time problems a while ago, and their solution was to get into the UI as quickly as possible, while continuing to load everything in the background. This is why Windows is damn slow after you boot and slowly picks up speed as everything REALLY loads.

The proper timing would be from getting out of POST and to being able to actually use the desktop, not to seeing the desktop.

I remember several benchmarks being published some 10-15 years ago, showing several additional minutes of severe slowness even when your basic desktop seemed to be loaded.

TLDR: this is an illusion or a dirty hack, depending on your preference in terminology

There is no "vSphere free offering", ESXi standalone is what you can run for free, with limitations.

Also, QEMU/KVM is not necessarily QEMU/KVM, KVM can be used separately, and so can QEMU.

And one last thing - in any article involving virtualization, it is important to explain the difference between a hypervisor and a full virtualization management product, as well as the many layers in between. vmkernel is not ESXi and is not vSphere, but people lump everything under VMWare and then do silly comparisons. A pure hypervisor is nothing more than a driver for the AMD-V/Intel VT-D CPU extensions, and nothing else. To turn that into a usable VM you need an emulator for the other hardware a VM has (which is where stuff like QEMU come in) with various levels of optimized hardware emulation and physical hardware access (paravirtualized hardware). These are already two layers of software just to be able to run a VM. And we left out the fact nothing can REALLY run on baremetal, metal needs drivers, so the "pure" hypervisor is really one of the drivers that exist in a set of drivers, schedulers and supporting software, aka the kernel. Xen is one such kernel with the hypervisor included. Linux with KVM makes another such kernel. On top of that you have the base management layer, so that you don't need to type in a 15-line-long command just to get a VM going, this is where you have stuff like libvirt, ESXi and so on. And the you get the datacenter level management layer (vSphere, oVirt) or the IaaS management layer (Openstack Nova, EC2 etc)

@nerdydad hard to tell. I was born in Georgia (the real one, in the USSR, not the state ), but lived most of my life in Israel, with a few years in the UK and Ireland.

@DustinB3403 said in Testing oVirt...:

No because I was so fed up with the instructions I close abandoned the test.

Well, oVirt is an opensource and free project. You want it to be better, get involved, even by reporting bugs. I really don't get people who expect to just have everything perfectly served up and for free.

Really, every time someone tells me this or that OSS project is bad, I ask for the links to the opened issues.

@EddieJennings it only took 'em 20 years

@scottalanmiller said in Testing oVirt...:

Yeah, DevOps in finance is old hat. They've been doing that for quite a while.

devops, config management, containers, kubernetes, a bunch of various big-data tech. When I see that mentioned, I can easily imagine what the structure of their currently developed software is - microservices all the way, no legacy involved.

And if anyone but us two is reading this - DevOps isn't new, it's as ancient as companies like Ford and Toyota, ask any business major (think of that over your next smoothie, young hipsters)

@scottalanmiller yeah, my visits were to Detroit (ugh, just ugh.) and Boston, which was actually pretty good, including pastries. I'll be in San Francisco next month, will see what I find there. Here in Canada, coffee and pastries aren't anything to write home about, but you need to know the right places - chains are notably bad, but some mom-and-pop shops can turn out to be very decent, and I'm pretty sure it's the same in the US (at least that was the case in Boston)

This is a cool wrapper for FIO, written by a colleague of mine. FIO provides you with the maximums, while this tool will allow you to measure the optimal settings and actual disk capabilities.

Since it's morning right now, I'm drinking coffee. Variating between Tim Horton's dark roast (I'm in Canada, eh!) and Israeli Turkish black coffee (Turkish grind arabica I buy in Israel when I visit there for work).

When I do feel like a stiff drink, I usually go for Tullamore Dew oIrish whiskey or Pere Magloir calvados

@FATeknollogee if you have an ovirt-engine somewhere central, that can reach to all the other locations, you can create a datacentre per location and place standalone hosts in there, using local storage. You will still have a single pane of glass to manage it all from a single address, a centralized VM configuration store, and the option to scale to additional sites or add hosts in a specific DC. I've run a RHV setup with ~300 hosts spread out across the world like this, and it was much easier than dealing with entirely standalone machines.

When I was picking a country to live in, the choice wasn't so great. My criteria were:

• English
• Free-ish medicare
• Affordable higher education
• Actual seasons with real winter and real summer
• A decent market for IT jobs
• A nice overall mentality
• A place where I can raise my kids without worries

It all converges on Canada for me. I've lived and worked in Europe, visited the US quite a bit and spent years in both the Middle East and Eastern Europe, so I have a fair bit of knowledge of what life looks like in other places.

I'm not chasing the big bucks, but I do want to live in a nice house in a nice neighbourhood and be able to afford enough luxury. In 5 years in Canada I got all that and more. Never going to be a millionaire, but that was never the point.

libvirt has dnsmasq built in, to serve DHCP. It can also be configured to serve DNS to the libvirt NAT network, and the host.

This is an example of a working configuration: https://fabianlee.org/2018/10/22/kvm-using-dnsmasq-for-libvirt-dns-resolution/

@scotth said in Gaming - What's everyone playing / hosting / looking to play:

I'm all about point & click adventure games. The 1st one I played was King's Quest 6.

Sierra! I got the entire series years later and clicked my way through it all using a dos emulator. The first ones were black and white iirc

I skipped the discussion, but I see two main points here:

1. Plenty of DSLs support both Windows and Linux, they are made for automation, use them.
2. For anything more complex, where you actually have to script and a DSL gets too clunky, bash/powershell also tend to get too clunky and hacky to be useful. I simply revert to Python - it runs on both platforms and is much more powerful than either bash or powershell.

@scottalanmiller said in IBM looking to acquire RedHat:

I would like to see @dyasny's feelings on this for sure.

We'll have to wait and see. Frankly, I don't believe IBM will allow the almost-startup-ish way things are done at RHT - dynamic, creative and open to continue. On the other hand - their track record isn't as horrid as Oracle's, so...

Still, I think I jumped ship right on time

OMG, NFS had the ability to mount with and without async and with hard and soft mounts since at least 15 years now. Well done on catching up MS, and pretending to provide a new and shiny killer feature

A Canadian(ish) here. Many years of experience with KVM and Linux, RHV/oVirt and more recently Openstack and k8s/Openshift. Moved to the big data domain a few months ago as a part of my midlife crisis routine.

@scottalanmiller I disagree. The last thing I want in production is to deal with tons of bugs and losing API compatibility, having to overhaul my automation all the time to readjust. I've had enough of that when I was working on Openstack, and the product was changed every 6 months so that my code had to be updated for every version over and over again. Fedora is great (I'm typing this message on F28 right now), it has been my desktop OS for the past 10 years, but as a server - no. CentOS is stable and predictable and is a very easy solution if your business intends to grow enough to move on to RHEL.

@scottalanmiller said in IBM looking to acquire RedHat:

OIC, yes, that might easily be. No idea what people are building on.

I've built quite a few, and very often I would come in, remove Ubuntu with Canonical's juju whatever or Mirantis fuel, and deploy, as a final production setup, not a POC. That was my job, pretty much, with Openstack.

@DustinB3403 said in Why Do Recruiters Never Get Involved in Forums Like This:

A recruiting company could post their positions on the forum.

And get swamped by people replying with questions they'd have to answer publically. Like "what are you guys paying?"
