Dumb question, but I'm on a time limit: If I make snapshot A, and then someone makes snapshot B. What are the implications of deleting snapshot A before B? I have a change management process but I didn't take into account that someone else would have a task that overran mine and I don't want to break things. Edit: Nevermind. B finished their work and deleted their snapshot. Panic over. Dr. Arbitrary fucked around with this message at 07:04 on Aug 5, 2016 |

For what it's worth it just rolls the delta of A into B right? Really any other alternative breaks B.

Yeah deleting snapshot A would just make snapshot B the diff between B and the original VM.

If it is good software it would have told you could not delete it because of child snaphots or something.

I was talking about this in the GPU thread, but it probably belongs here instead. Trying out GPU-passthrough to downsize the number of machines I have. Currently I have an always-on linux box that's my desktop/development station and runs some services for my home (PLEX transcode, etc). Sitting next to it, hibernating 99.9% of the time is a box just for gaming. Setup is Qemu/KVM on an i5-4590 (non-k) with VT-d enabled. GPU passes through fine, but the USB is all sorts of hosed up. code:Bus 001 Device 002: ID 046d:c531 Logitech, Inc. C-U0007 [Unifying Receiver] Bus 001 Device 007: ID 041e:4088 Creative Technology, Ltd Live! Cam Chat HD [VF0700] Bus 001 Device 009: ID 0a81:0205 Chesen Electronics Corp. PS/2 Keyboard+Mouse Adapter The webcam works, but the mouse & keyboard both show up in device manager as yellow triangles. Bootup on qemu is silent, but the host kernel gets upset about USB shennagins: code:I tried putting in a PCI USB card to pass through directly, but it gives me poo poo no matter which slot I put it in. It's in it's own IOMMU group, but the interrupt is shared and refuses to honor remapping.

What's the lowest power (and cheapest) hardware requirements for a small, home ESXi buld? I want to uprade my home server and I fancy virtualisation his time. I will only be running two or three VM's on it, so powerful hardware isn't required. I have a WD red 1TB and small 64GB SSD to keep the OS on. I also have spare powers supplies (one almost brand new and a never used PicoPSU and power brick). I also have decent 4 GB of decent G.Skill RAM spare, so all I need is a CPU and motherboard. I tried running ESXi 6 on my ancient Clarkdale i3 CPU and it just hung during the install for 30 minutes, with no indication that it was doing anything. Would a modern, low power, desktop CPU work? Or am I kidding myself. Something like this: PCPartPicker part list / Price breakdown by merchant CPU: AMD 5350 2.05Ghz Quad-Core Processor (£34.64 @ BT Shop) CPU Cooler: ARCTIC Alpine M1 - Passive Fanless CPU Cooler (£5.28 @ Amazon UK) Motherboard: ASRock AM1H-ITX Mini ITX AM1 Motherboard (£50.00 @ Amazon UK) Total: £89.92 Prices include shipping, taxes, and discounts when available Generated by PCPartPicker 2016-08-07 09:48 BST+0100 Or am I kidding myself and need to step it up to an i3-4170, or even or something more powerful? I was hoping it's just the ancient architecure on my Clarkdale i3 that's preventing ESXi from installing. I would love to get down to the PC store today and get some some modern server hardware to get this project going.

The USB turned out to be a combination of things: Windows being windows and making GBS threads up the DriverStore (copied new usb* from install.wim to fix it) and the PS2/USB adapter being a piece of junk. Unfortunately, even after all that I only got "near native" performance on benchmarks and some games. Others were running at unplayable levels of FPS for some reason. I'm going to attribute it to the only-partial VT-d support on H97 (IOMMU, no IRQ remap, maybe other limitations?) and try it again when I get better hardware. I tried the obvious fixes: CPU pinning per-thread, hugepages instead of 4k memory maps, every driver possible to virtio, moved the sound from emulated to running through the HDMI. DPC Latency was pretty horrific comapared to a raw machine - raw was max ~150us, qemu was minimum 1500us, spiking up to 20k or more. If that's applying to draw commands than the difference is probably big-batch vs small-batch game engines. Harik fucked around with this message at 16:09 on Aug 7, 2016 |

I run ESXi on an old Core 2 Quad CPU, but I have 16GB of RAM. An older i3 should be able to keep up running a limited number of VMs. 4GB isn't really going to cut it though. I wouldn't run less than 8GB for virtualization. Also, make sure you've got VT-x or whatever enabled in your BIOS. HPL fucked around with this message at 20:20 on Aug 7, 2016 |

I tried it with 8GB RAM (4 GB temporarily removed from desktop) and still no dice. I will examine the BIOS settings for all Virt related stuff, tomorrow.

It's a really old Clarkdale i3-540, coupled with a GA-H55-USB3 motherboard. http://ark.intel.com/m/products/46473/Intel-Core-i3-540-Processor-4M-Cache-3_06-GHz http://www.gigabyte.com/products/product-page.aspx?pid=3455#ov It should have enough grunt to do what I want to do with it (store business files and stream music/video) but I'm leaning on building a new system with more modern architecture. E: could it be the on-board LAN? Do I need a dedicated network interface card for ESXi? DeaconBlues fucked around with this message at 15:43 on Aug 8, 2016 |

I've been trying to play around with server 2016 in hyper-v but I've run into the dumbest problem- my keyboard strokes aren't passing through to the vm. I guess I could build an unattend.xml file and then log in remotely, but that would be giving up, right? Does anyone have advice? e: I rolled back the anniversary update and the vhds I could produce behaved normally.

I'm in the same place with an Oracle E-Biz system with users who (1) can't let me discard decades-old data to a non-production DB (2) can't write reports that exhibit any level of mindfulness for efficiency (3) won't put these reports in our digital document / OCR system and instead re-queue and re-print them every time someone needs to see <report result>. Someone, please for the love of God, make an affordable turnkey SSD storage filer. You are going to have to eventually.

I don't know about Linux, but if you change the adapter card, it will treat it as a brand new device, ignoring all old settings. You also can't remotely configure a server that's off the network, so you have to make a script that can grab the old info, wait for the change, and then put in the new info. Not a simple script.

You use powercli to change the type and the mac will match the old card. We went through this ourselves, it was stupid simple. It might have required a second reboot.
