Rrd files are just nasty. We had to turn off data for things that our noc would like to have but wasn't necessary. Fortunately the new environment is built with a staging environment in mind to allow testing of 5.x without taking down the existing.

We could've used fiber but the expense was too high so instead we use the fiber to support our vms over clvm so we can pass them around instantly via kvm. I've had good luck w/ rrdcached, if you can handle a few seconds delay for the data to coalesce. Lustre's really optimized around 1MB block writes so I can imagine RRDs on top it that being... interesting.

Kind of tangential, but if you're using clvm-backed libvirt datastores and passing VMs around that way, you may want to take a serious look at management platform. Any management platform (Ganeti, oVirt, Xen Cloud Platform, maybe Archipel if it's still active)

Looking at upgrading the ram in some of our hosts and trying to work out exactly what type of DIMMs we have installed without actually opening them first. In vSphere it reports "Memory Type:24". Anyone know what this corresponds to ?

Maybe someone here can provide insight on a problem I'm having: I have two ESXi 5.5 hosts that are not part of a vCenter or anything. I shut a VM down on one to move it, but now it can't be powered back up at all, it claims the vmdk file is missing. In the data store I have: <vm>.vmx <vm>-000001-sesparse.vmdk (about 5GB) <vm>-sesparse.vmdk (about 1.5GB) Have I seriously hosed something here? Is there some way to recover this? I tried mounting both of those vmdk files in workstation 10 but it said they weren't vmdk files.

We've had a similar issue with Commvault not removing the snapshot properly and leaving the VM unable to boot. To fix our issue: 1) Remove the hard drive from the VM, but do NOT delete the vmdk. 2) Add a hard drive back to the vm, and make sure it is SCSI 0:0. Select the existing vmdk that is most recent, which sounds like <vm>-000001-sesparse.vmdk in your case. 3) Boot and hope for the best.

I'm running virtualbox on an X99 host system (64 bit win7) with an 8-core 5960x and 64gb ram. Here are the full host specs: http://pcpartpicker.com/p/LQZHrH I've got 8 guests (32 bit winxp) that I run concurrently all day. Each is only used for browser work, connected to either openvpn or putty ssh. How many cores should I give each guest? They're each allocated 2gb ram. Also, is there a more efficient setup I could be using for what I'm trying to do? Namely, having 8 different "walled garden" boxes (all initially cloned from a basic winxp install), each with their own IP, doing very basic browser work all day and nothing else. I've noticed that even on my newly built top of the line host system, the guest boxes themselves are sometimes sluggish and unresponsive and I'm not sure why!

Internet Explorer posted:This is good advice. Especially about the SSD. How many cores are you currently giving each VM? For what you're talking about 1 vCPU per would probably be best. I'm currently assigning 4 cores to each box (I was giving two cores to each when my host had 4 cores + HT so figured doubling them on this host made sense). Could this actually be hurting performance? Everything is running on an XP941 M.2 PCI-E SSD (about double the bandwidth of sata3 SSDs). edit: I'm also wondering if winXP simply isn't optimized enough to take advantage of some of my current hardware (esp. given that the guests are 32bit each), so perhaps I'd actually see better performance upgrading them to Win7? I'm worried about it having a larger footprint/using more system resources, however. Even with 64gb ram, running all 8 guests keeps my host system at about 50% ram utilization at all times. One last thing, these boxes were all created long ago on a different system and dropped into this one. Would there be any merit in re-creating each guest from scratch on my current host hardware?

I would bump them down to one core unless the things you're running really absolutely need more. Are you accessing them through the virtual box console, or through remote desktop?

Could this actually be hurting performance? Changing them to 1 vCPU per should make a world of difference. WinXP should do fine enough. Going to Win7 or even Win8 would help as they do a little better with slower IO. Sounds like you are fine on RAM. If they were created in VirtualBox it shouldn't matter where they originally came from. Try the 1 vCPU bit first and go from there. Should be a pretty big improvement.

Yeah, a few of us use Veeam. Do you already have Veeam and you're trying to learn it? If you can't consolidate a VM because of a file lock, it's because the vmdk is also attached to the Veeam proxy that last backed it up for some dumb reason. That's the main problem you'll run into, and otherwise it's gotten a lot better than it used to be.

I am trying to teach myself more things about Linux and Microsoft AD at home. What I want to accomplish is to setup a fictitious company Contoso. I'd to have a PDC, SDC a few desktops. Create the contoso.com domain, a few desktops, users, experiment with group policy, etc I'm starting out with VMware Workstation 10 on my local PC but is this going to work? I'm noticing that things are slower than I expected despite my host just being a i5-2500, 8GB Ram and Samsung 830 SSD. I know I will eventually need more RAM that's fine but how much more performance will I get if I have a dedicated physical host? I could get a i5-Haswell, 16/32GB RAM and bigger SSD. Hyper-v looks like the best choice as if I went with ESXi I'd need another physical (I guess now you can virtualize it?) host for V-Center but if I need a host for less than a dozen VMs would this setup be the best/easiest? I'd remote in from my main desktop for actual work.

I use the virtual appliance for V-Center on my single host, but for the most part, I leave it turned off because it doesn't do much if you only have one host. I think VMware is a really easy approach, but it's probably a great idea to learn how to do things with both VMware and Hyper-V. Edit: RAM is my biggest bottleneck. Going from 8 to 16 GB was a big boost, from 16 to 32 might be less noticeable.

PDC and SDC are dead paradigms, just FYI. Scrap whatever you're following which uses those. Memory may be a bottleneck (KVM and VMware's products are much better than hyper-v with limited memory). It's also possible that you haven't enabled vt-x, but it's hard to say without perfmon and an actual description.

Tab8715 posted:What's the new recommended design? Someone correct me if i'm wrong. I believe it is the FSMO (Flexible Single Master Operation Roles) which consists: PDC Emulator, RID Master, Infrastructure Master, Schema Master, Domain Naming Master. If you are just looking at learning basic AD administration and group policies. You should be able to get away with one DC that would essentially hold all of these roles. If you wanted to look deeper into replication and transferring the FSMO roles go with a second DC. As evol and others have said bump up the ram in your PC. You should see a noticeable performance boost. If you don't have one already throw in a SSD to run the VMs on. You could also take a look at Autolab, it's a nifty solution for running a lab on VMware Workstation. It might complicate things a bit (I don't mean complicated to set up, just more geared towards learning VMware) and it takes an hour+ to set up the first time. Once it's going and you are familiar, it makes tearing down and rebuilding a lab really convenient and you can get a couple hosts, vcenter, and shared storage running all on the same workstation with minimal resources required.

I did not know this but you prompted me to quickly look it up and if I am understanding this right: "nltest /dclist:contoso.com" would query active directory for a list of dc's (one of them will come back as [PDC]) and if unsuccessful, nltest uses the browser service. I think the DC that returns as [PDC] is the PDC Emulator (at least).. so basically the PDC in a older Windows NT/AD infrastructure?
