Syano posted:Barf. Good luck with them man. We just had to forklift all ours out cause we hated them Ditto that. We had a reproducible problem where rebooting a certain server would bring down the portchannels to our SAN. We already had cisco switches to replace them, so we just took then out of production and recycled the evil things.

Can anyone say whether or not Xen changes the UUID of a VM when it's migrated? We have a vendor whose lovely ecommerce site apparently is tied to the machined UUID, and they say it changed last night. The hosting service we're using is running Xen, which I haven't ever used.

To be clear, I'm talking about the internal Win32_ComputerSystemProduct UUID, not the UUID of the VM.hackedaccount posted:A couple questions come to mind that might help people answer your question: It's a hosting provider, so I can't say exactly what happened to make it change. They had some major downtime a week or so ago, but the UUID change resulted in a shopping cart process breaking due to some "unknown specific key" error. Can someone with Xen try migrating a VM and just "(get-wmiobject win32_computersystemproduct).uuid" from powershell before and after? I can't believe it'd change, but who knows.

No, there's a few limitations on Hyper-V in Windows8 but none of them will probably matter to you. You don't get Live Migration, RemoteFX, SR-IOV, virtual fibre channel, and some other irrelevant poo poo for a desktop lab.

Cronus posted:Does anyone honestly use FT in production? I don't think I have ever heard of a case. The only thing I can think of for it being used would be some Win2K box running a mission critical app that no one understands anymore. I don't think so. The 1 vCPU limit pretty much means any guest where FT would be really nice can't use it anyways.

This question's probably aimed at evol262, but here for anyone else as well: We've got some junky vendor Windows application which they seem to tie to the UUID accessible via PowerShell in the win32_computersystemproduct WMI object, which is linked to the IdentifyingNumber in that same object (pulled from CIM_product apparently). As an example from a random VMware VM in my infrastructure: code:On the VMware side, this UUID is specified in the vmx configuration file and shouldn't ever change: code:On that machine, the UUID seems to fluctuate periodically, which breaks our vendor software. Checking the same WMI object on that server: code:

Mission-critical apps that can't be down for as long as it takes HA to kick-in, yet still only require 1 vCPU? Yeah, you're not alone in scratching your head at that one.

Wicaeed posted:Does anyone know what might have stopped an otherwise well behaved vCenter server from displaying performance information for a SAN disk? I get the disk space stats just fine, but when I go to load any performance related information from the 'Datastore and Datastore Clusters' tab, I get a 'Could not load data' error across all performance information and performance information time periods. Probably this bug. You can view Realtime stats, but not historical stats, right?

Is there any reason why I shouldn't rely on vmkping as a troubleshooting tool? We've just moved over from 1gig to 10gig backend fabric, including our vmotion traffic, and I'm seeing some strange timeouts when certain hosts try to vmotion to other hosts - no pattern that I've found, but I'm trying to test with a vmkping from the vmotion vmk interface on host A to the vmotion vmk interface on host B and VMware is telling me that vmkping isn't always reliable. So far it seems to match up reasonably well with the reality of what I can and can't vmotion, so I'm not sure what VMware's talking about.

Thanks Dilbert and KS for the responses. I had several different things I had to run down, but KS was on the right track with multiple vmotion interfaces. Disabling vmotion on the old 1gig fabric's vmkernel interfaces was something I'd forgotten to do, so it put me in the strange spot where vmkping would fail (we'll get to that in a second) but vmotion would succeed (because it was going over the 1gig fabric). The vmkping issue was caused by a misconfigured portchannel between our two 10gig switches. We have a vmotion-enabled vmkernel interface on each host with two active vmnics - if the vmnics in use by the vmkernel interfaces on two hosts were connected to the same switch, it'd work. If they were on different switches, it wouldn't work. Simple enough once we realized what was going on, but assigning active/active vmnics to a vmk just let us assume that it would work if at least one path was valid, when in fact it pics a vmnic and sticks with it (on boot?).

Martytoof posted:Am I losing out to too much by specifying HW7 when creating new VMs on 5.5? I want to be able to manage them using the thick client, even though I'm kind of coming around to the Web UI for most stuff (Mac user). If I'm really losing out on some awesome performance options then I'll go to whatever new HW version I need, but if it's just fluff then I dunno. Are you just dorking around in a lab, or is this for a production environment? Comparison here.

Anyone know if this KB article also applies to 6.0.x? I'm pretty sure we just experienced exactly this issue - one VM went unresponsive, then the entire host freaked out and we ended up pulling power from it because no shutdown options (for guests or the host itself) were actually working. However, we're on 6.0 and the KB article says applies to 5.5.x and 6.5.x.
