I agree with you but I am not planning to move unless I can get a garunteed job somewhere else, moving and YOLO'ing isn't exactly how I'd like to do it. I would like to hit 25, with some ample savings then choose the best option. 5.6, yes I agree 6.x is great, but this is for the UNIX 1 course, where they learn bash, scripting, and some of the syntax. It's 5.6 because the current curriculum works with 5.6 and 6.x doesn't offer much over what the students can't get in 5.x, and UNIX 1 never goes into the deep features of RHEL 6.x; that is for UNIX 2 the RHCSA course. Right now it is the pilot stage, so yes while I could use 6.5(is that the latest?) I couldn't go back to the directors and go "here is a 1:1 of how poo poo worked". I'd like to change as little as possible to how the course is taught/interacted so I can focus on showing how well the course worked with my design improvements, then come back to the "let's use 6.x". Right now it is a burden for teachers wanting to upgrade and setup the environment, with my vAPP or linked clones it is much easier. It's really not my say to waltz into the *nix teachers and tell them to upgrade, but doing it this way does help reduce quite a bit of the burden on the teachers for setting up labs and such; thus making updating a more viable and appealing task.

I just wanted to reiterate that there is nothing wrong if you understand the caveats with 5.x, and that it may even be a good thing for infosec, and it isn't worth retraining. I only asked initially because it's weird to see someone ask about 5.x in 2013. Nothing wrong with it, no criticisms, nothing to see here.

Instead of having each of our 6 VLAN's on their own NIC to just bond them all together and make a vSwitch or something that contains them all? Is there an article that explains this a little bit more? It just seems wasteful to do it that way when we have very little traffic on two of them.

Is there an article that explains this a little bit more? It just seems wasteful to do it that way when we have very little traffic on two of them. I guess your real question is what each of those VLANs is doing. The canonical way is basically: If the VLANs are for vMotion, svMotion, storage, vmkernel, or management, segregate them enough that you can jack up the MTU and that high traffic on one won't bother guest traffic, storage, vMotion, or management. This usually means physical NICs the way you have them. If the VLANs are for guest traffic and you have enough traffic on any VLAN to saturate a link, it should get its own NIC or two, depending on traffic. If there's not that much guest traffic, usage is irregular, or whatever, bond everything and assign VLANs in the guests. Without knowing your current setup or needs, it's hard to say.

If you were building an ESXi server you'll probably want to configure the switchports your ESXi server is plugged into as VLAN trunk ports and add all your VLANs. Then on the ESXi side create a portgroup for each of your VLANs.

I Am Not A Network Engineer, but I was wondering here: What if you did aggregate the physical links after all, and used QoS to prioritize or limit bandwidth for each VLAN accordingly? Also, if I'm not mistaken, vSphere 5.5 dvSwitches support DSCP. Are these things helpful enough, or a better practice, or should links indeed be separated because this perhaps introduces too much configuration complexity? I also suppose VMware NSX will up-end all of this as well.

You can do via PG on a vDS limiting ingress/egress traffic traffic, VSS's do egress only IIRC. You'd then tag the PG's with vlan's as 101 was saying.

I was trying to rsynch my roommate's movie folder share from his ESXi box to mine, but for whatever reason instead of going to the 4TB RDM I have set up on my linux VM the movies started copying over to my datastore. I read somewhere that ESXi likes to store everything on the datastore before moving it over to the RDM to prevent the loss or corruption of any data. Has anyone ever heard of this, is that correct, and is there a fix so that my 300GB datastore drive doesn't get killed by trying to rsynch 2.5TB of movies? And in other news I have the components for a home NAS coming early next week - I had a machine with a Core2Duo sitting around collecting dust, so I ordered some additional RAM and a 4-in-3 drive enclosure and I'm going to build me a Frankenstein box and throw FreeNAS on it and go to town with 4x2TB Seagate NAS drives. I'm pretty excited to play with it in ESXi and can't wait to see how it performs on my network. Daylen Drazzi fucked around with this message at 15:07 on Nov 30, 2013 |

What?? I think you want to use the Linux Guest OS to do the actual file copying so it ends up stored inside the virtual disk. Does your friend have an NFS share or something? Mount that in Linux and copy it into your RDM that way.

You have VM "A1" running on "A" with your RDM RAID 0 attached and he has VM "B1" running on "B" with some sort of storage that doesn't really matter here. You want to copy files from "B1" to "A1", so you logged in to "A1" and ran an rsync connecting to "B1". Somehow those files ended up on "A"'s datastore instead of inside the filesystem "A1" has on the RDM RAID. Is that correct?

I was recently thrown into a virtualization project due to me knowing more than nothing about the process, but the environment they want created is fairly large and I was hoping someone could give me some advice. I am deploying a new VMM 2012 R2 server with 44 2012 r2 hyper-v hosts, each have a quad port nic and 2 onboard nics, all ports for all hosts are on the same vlan and subnet. I have been reading some blogs about SCVMM best practices and one of the primary things it says is try to separate out different types of traffic using VMM. I'm afraid I'm a bit of a dud when it comes to networking and i was hoping someone could help simplify the process. If all the hosts are on the same vlan and subnet how can you separate out the live migration traffic from the host management and guest traffic? I do not have any control over the switches at my company and I would like to be able to avoid any direct manipulation of them. We are not doing any Iscsi traffic, all hosts are in 5 node clusters. There will be between 4 to 8 guests per host. If any additional info is needed i would be happy to provide.

I fixed the VM issue by deleting all snapshots, but I need to figure out how to avoid the files synchronizing to the datastore instead of just going straight to the RDM RAID. At least, that's what I think - I'm just guessing here.

I'm looking to build a hybrid ESXi / HTPC server and I'm want to get GPU passthrough working. The ESXi server will be serving mostly light weight duties so I'd like to also use it as an HTPC. I've decided on the following parts: ASRock E3C226D2i Xeon e3-1240v3 OEM 16 GB ECC DDR3 Unbuffered Spare SSD or USB drive for ESXi install I'm trying to figure out which video card to grab. I was hoping someone has done this before and could recommend a well supported graohics card. The most strenuous thing I'll be doing is pushing 1080p video to a 1080p display so almost any video card should do. The ASRock board doesn't support Intel graphics and has a weak GPU for IPMI.

Make sure the motherboard supports VT-d Make sure the motherboard supports VT-d Not VT-x, though you need that, too. Get any GPU you want. Pass it through to a guest with VT-d. Consider using Linux+KVM, Xen, Hyper-V, or a Raspberry Pi. ESXi+pass through works if you have to do it, but it's frankly not the best solution for hypervisor+htpc

As far as I'm aware the guests have no ability to see VMFS, nor is ESXi aware of the filesystems in use on RDM disks, so I really can't think of any way this is happening without an error in your rsync command or the terminal you selected to run that command resulting in the files being rsynced to ESX rather than to the guest. Or are you just assuming they're landing in the datastore because you're getting the out of space error? Does your VM have any sparse provisioned disks within the datastore, where the apparent size would exceed the datastore free space if it was to be filled? Could the VM be caching received files there before writing to the RDM partition, thus causing it to balloon up and run you out of space? wolrah fucked around with this message at 05:29 on Dec 2, 2013 |

I must be missing something, but is there an easy way to create a bunch of linked clones in vSphere? I'm setting up a test environment for a project I'm working on, and it would be nice to save the storage space. Hyper-V calls them differencing disks I think, I'm looking for the same thing basically. One master image and then just the deltas for each VM elsewhere.

It's academic at this point, however, since my FreeNAS server is up and running and working like a charm.

I decided to install ESXi 5.5 (I guess vSphere Hypervisor now?) because I've never used a bare-metal hypervisor and it looked neat. The install went fine but apparently I can't manage it directly, but need to install an admin client elsewhere? So I installed vSphere client on a WinXP VM but apparently 1) vSphere Client doesn't work on XP and 2) doesn't support everything ESXi 5.5 does? So even if I installed a newer Windows I still couldn't manage everything? Are you really supposed to be able to use ESXi for free? Or can I not really use it unless I buy some admin console thing? Is there some other way of managing it (like a web UI or Linux binaries or something)? I clearly have no idea how I am supposed to use ESXi.

What's your goal in using VMware ESXi? You're right that it's not meant to be managed directly from the console and you need to load the management client on another machine. It's definitely not a product in the same space as something like VMware Fusion, Parallels or VirtualBox which I (maybe wrongly) get the impression you're looking for. For any non-toy use it's meant to be licensed and then used to run dozens to thousands of VM's, and yes you will need to pay for that functionality. Mostly unrelated but I'm not sure why the Christ you expect anything to support Win XP in 2013, it's more than 12 years old

I assumed I could admin a single ESXi easily, but maybe not? Are you saying the vSphere Client works well as long as I use something newer than XP? Or don't bother with ESXi unless I'm going to fork out for the real client admin tools? The only Windows licenses I have handy are XP licenses and I figured the client is just configuring the server, why does that require a new version of Windows?

We use free ESXi for pretty much all of our clients. You can still manage pretty much everything in the client still these days. Most of the features that are in the Web client only are geared towards vCenter deployments.

I don't see any way of them avoiding releasing a "free vCenter" as a virtual center appliance, unless they are planning on running web and management within ESXi itself, which I highly doubt will happen.
