Woof Blitzer posted:Is it possible for virtualbox and hyper-v to talk to each other? Hypothetically yes, might be able to bridge the Virtual Switches/Network Adapters or even put Virtualbox on the Hyper-V Virtual Switch. I've done it before, but it was several years ago. Might try tonight.

Woof Blitzer posted:Success! The host received a DHCP reservation. So it turns out Hyper-V and Virtualbox can coexist which is great as all the boxes I downloaded from VulnHub are .ova format. Another option is to convert the VMDK to VHDs and they should be bootable from HyperV directly.

Paul MaudDib posted:A while ago I was trying to use Virtualbox and I was getting weird errors that eventually tracked back to the fact that I'd installed HyperV at one point, wanting to give it a try. Apparently HyperV is always running and if you have HyperV installed then it hogs the VT-d hooks so no other VM implementation is allowed to use them. HyperV is actively used for sandboxing apps in some cases right now, and Microsoft has said they are going to use HyperV to do security features more in the future.

SlowBloke posted:ESXi has stopped being hobbist friendly at 5.5, everything else has been a race to gently caress up non standard setups. With William Lam using nucs as test beds, those are your best bet if you want to homelab, making your own server is currently an exercise in frustration IMHO. Just use XCP-NG or Proxmox. And no, Nucs are very expensive, just purchase Dell/HP USFF machines for half the cost and upgrade them. As it is, I'll stick with XCP-NG, they haven't cut legacy support and are unlikely to do so, and work happily on my Dell Bladeservers with Opterons and Xeons. You can get out the door with a Dell R720 for the same price as a Nuc. CommieGIR fucked around with this message at 17:41 on Aug 19, 2021 |

rufius posted:Alternatively, the little NUC I bought (https://simplynuc.com/ruby/) sips power. Okay that's Ryzen powered so I do want that. drat you, rufius. For perspective: My current workstation is a Asus ROG laptop with a Ryzen 7 4800H 8c/16t and I use it mostly for virtualization when I'm not playing games. Looks like its got both SODIMM slots available too, so yeah you should be able to crap 64GB of DDR4 into that too.

Clark Nova posted:II'm pretty sure people are passing on these due to noise and power consumption. I've been waiting a while for a really good deal on something tiny with two NICs or a PCIE slot with no luck The Ivy Bridge runs actually consume not much for a 1U/2U, I have one that idled at about 300 watts. rufius posted:Also - because I'm a heretic, it runs Windows Server because I prefer Hyper-V (I worked at MSFT for a long time - I'm used to Hyper-V). I use HyperV on my workstation because it just works and I don't really have to install anything. Works great.

Martytoof posted:Agreed. My R620 with idle VMs, six spinning 10k disks, two 20-threaded E5-2660 Xeons, 128 gigs of ram, six or eight spinning 10k 2.5” drives and it is currently idling at 168W. I’m pretty sure I have it in ultra conservative power usage mode but it’s never felt slow or lacking. My workloads are all idle right now so I’m sure it bounces up but I’ll take that 168W idle any day. My main NAS is an R720 with 2 x 12 core Xeons and 128GB of RAM + Spinning disks and under load maybe hits ~350-400 watts. It hosts the storage for my M1000e Bladecenter

GrandMaster posted:Exactly, they shouldn't need high io. The tools mount/scratch run from ramdisk and logging goes to san datastore. What else does the card need to be doing? There was always the possibility you corrupt your SD card, in fact a lot of Hyperconverged stuff either uses Mirrored SD cards or SATADOM modules to address this.

barnold posted:slightly random question for VM goons: what makes Win9x so difficult to emulate? I understand that virtualization companies largely target professional-use OSes and not consumer ones like 95/98/Me, therefore there is little incentive to provide support for it, but it seems to be the one major glaring hole in VM tech. Everything up to 3.1 seems to work great in DOSbox, everything NT4 and up works great in almost everything else. We can emulate 64 core CPUs and hundreds of gigabytes of RAM, but we can't emulate a single-core Pentium and a Rage 128 well enough to not have cursor trails all over the screen in normal use? Too much blue plate special spaghetti code? As the above already states: Emulation and Virtualization are different. The problem with virtualizing legacy tech is not that it can't be done: It can! The problem is you are basically putting a legacy system onto a modern architecture (i.e. If you install Windows 3.1 inside a Xenserver VM on AMD Opterons, guess what hardware that machine is going to have? That's right. Windows 3.1 running on modern architecture, at modern speeds). Emulation is neccessary because you have both be able to step down the architecture, step down the speeds to something more in line with the hardware the OS was made to live on in the first place. You gotta slow it down, and in the cases of stuff like graphics, you have to emulate older GPUs that look nothing like our modern equivalent. Otherwise, you can run any OS made for x86 hardware on any virtualization platform.

Yeah NFS has changed significantly, there's still some compatibility issues which keeps SMBv3 king of the roost for file shares, but NFS has significantly improved.

Yeah. K8s/K3s are great if your service is lightweight enough to be scaled that way. The average application is not. Ask me about trying to convince Devs not to roll entire Java apps in K8s and then rolling my eyes when they didn't understand why it was so slow.

SlowBloke posted:It seems like Broadcom might be planning to purchase VMware for ~60B$. Given their previous software purchases, expect them to make it far worse than today support wise(which isn't stellar already nowadays) and kill any community outreach. Yeah Broadcom seems to poison everything they touch. The fact that they bought Symantec which was already collapsing like a broke tent was confusing.

Boner Wad posted:I have an ESX 8.0 machine that has 4x drives on a raid controller with the raid controller passthru'ed to a VM. I installed ESX onto a USB drive. I had to use an NFS mount for the VM guests. Can I put another USB drive in there and use that as my VM guest datastore? How do I do that? I think I tried to put a USB drive in before and I couldn't get it to show up as a datastore. I mean you can do USB passthrough, is that the goal, I wouldn't try to host anything data intensive on a USB drive.

Saukkis posted:What is everyone's view on Veeam and Russia? We are testing image backup systems and we dismissed Veeam because of the Russian origins, but maybe it is separated enough nowadays? It is owned by venture capitalist Insight Partners from New York and on the top management there seems to be only the R&D chief who might be from Russia based on the name. Veeam largely is US based now, their HQ is in the US and they are primarily registered as a US business' entity.
