Can virtualization give my host computer vicarious access to hardware it otherwise wouldn't have, or do I not understand virtualization? Or does a VM have no access whatsoever to actual hardware. There are instances where the guest can have direct access to io hardware running on the host by means of vmdirectpath, but things like network devices are typically abstracted by the hypervisor. In your case I don't think virtualization will help. Someone with more knowledge feel free to correct me. some kinda jackal fucked around with this message at 00:02 on Aug 28, 2013 |

I rolled out vCOps today, it took about 3 hours start to finish. This included reading the installation and user guide. I also ponied up and took/passed that new VCA cert test for data center virtualization. It took considerably less time.

It seems that OSX could probably be beaten into using my PCI wwan card after all, since it comes with support for a bunch of devices already including ones by my vendor ID (Sierra Wireless).

It was available as a free VPX which you just deploy in your environment and then hook up to your vCenter server. You could run growth simulations on your current environment to predict when resource shortfalls would occur. Also it had pretty graphs which everyone loves (I know I do). The first result on Google for CapacityIQ leads to a 404 however if you view the cached version it says that the features in CapacityIQ were rolled into vCenter Operations Management Suite and that CapacityIQ was subsequently forced into EOL.

And by training, I mean "basically a three-hour VMware ad with no content whatsoever". Since I have no VMware certs, and don't have the time/resources to get a VCP right now, I might get this to have something that looks good on a resume. Should be dead-simple to pass the exam even with almost no hands-on VMware experience, and the price is right. I'm under no allusions that it's actually worth a drat, though.

I found it a little bit useful in terms of sorting out the hundreds of terms that are used to explain various things, it's all stuff I knew from having used the product but there are worse ways to prove you have a slight clue of what you're talking about. I'm in the same position re:VCP so I'm hoping I can throw this on a resume and end up working somewhere that sees the point in training people. I definitely don't regard it as anything to shout about though.

Move to the bay area. You will quickly get sick of people talking tech. You can't sit in a coffee shop in Mountain View without hearing 5 different conversations about how great the project at Google is, or how their social start-up is going to change the world. It might even lead you to take up following a sports team, just so you have something else to talk about.

It sucks so much because they're barely even talking tech, they're 'talking shop' just like pricks on the subway. They're talking about their money and people who are getting in the way of it. It's banned in many places including some cars on my commuter train because it's awful to listen to. Salvos of bullshit have splash damage, and there is nothing more bullshit-laced than the confluence of tech and business. Blame venture capital and Ayn Rand for sucking the life out of it all, I guess.

Can anyone recommend any primer reading or best practices doco for ESX to HyperV migration? We are looking at migrating our little 2 node cluster remote sites to HyperV to save a bundle on licensing, and since they only run basic file & print it's not considered a high risk. I'm most interested in the networking components such as splitting management from vm traffic, links for clustering & live migration, iSCSI, NIC teaming (using either microsoft teaming, or the intel utility) etc. GrandMaster fucked around with this message at 06:16 on Aug 29, 2013 |

One example I could think of though, you want to get a VCDX cert, so VMware, what if your boss came in and told you had to now flip over to Hyper-v or Xen instead? Understanding it isn't really easy, but put simply it can be just plain old "burn out". There are plenty of things I think are cool and I love to learn, but not always the same subjects I did in the past. Another aspect, there are a ton of people in IT who only did it to make money, they don't have any real drive or passion for the tech. It's a paycheck to them.

To fix it we ended up having to do some command line fuckery to create a vSwitch, move vCenter over to it. We left vCenter on the vSwitch when we got it back up and plan on keeping it there.

Have problems with dvSwitch and break things? Good luck if you're a novice. You could shut down your vcenter server for a week if you wanted to and not have to worry about loss of network until a host dies or you want to make a change like creating a virtual machine. That said there is no such thing as a non-important management server. All of your monitoring ends up going through vcenter server anyway and it should be treated about the same as any other tool you depend on to keep your environment running. Customers/end users may not see it but operations people certainly will. I end up gaining better link utilization (LBT is great for novice admins) and I gain per switchport policies (much better for security and overall management), persistent port tracking, netflow and SPAN support. I can still use a standard switch for vmkernel/vcenter/major dependencies or I can use ephemeral binding with a vDS for things like VC, SQL and AD and not worry. Either way it's a small amount of additional complexity for getting much better visibility into the network. re: the vCloud stuff, anyone with developers in-house has a number of reasons to look at vCloud/openstack/AWS. Conceptually the whole self service/completely arbitrary infrastructure is the bit that has a bright future.

Heartbeat, SQL clustering and some automated way of rebuilding vCenter from scratch in under an hour if for whatever reason it dies. All of your VMware monitoring ends up in vcenter server? Why not treat it as a fairly important system? My personal environment I just use HA with ephemeral port-binding (for vCenter, 1 AD server and my database server) and I can rebuild vCenter from scratch in ~15 minutes but so far it's had less than 10 minutes of vcenter outages in the last 12 months. All of my management vmk interfaces are on a standard switch but every virtual machine sits on the vDS. That said if your vCenter server is down the only things it impacts during that are creating VMs and being able to vmotion things. You can't really create a VM without vCenter server anyway so it doesn't matter that vCenter is unavailable to deal with assigning a static port binding. quote:I don't even think most companies should use the dvSwitch unless there is a feature they require. Even when I had ~15 virtual machines I still needed visibility into network traffic and some relatively sane means of distributing my VM traffic over multiple links (preferably over multiple physical switches.) Exporting netflow data and being able to wireshark network traffic is tremendously helpful in troubleshooting those "oh it must be VMware" issues that pop up non-stop even today. Load based teaming is about as simple as you can get and would work with everything from a dlink switch to a nexus 7k without having to depend on configuring port-channels or deal with hashing algorithms. Essentially the vDS has more positives than negatives as your environment grows and it's worth spending the time to understand how it works.
