Why would you subject yourself to Oracle's licensing extortion if you don't absolutely have to. I didn't choose Oracle, but I was one of the people who had to design, purchase and build a new VMware cluster after Oracle sent their goons for a visit. I would have had better things to do.

God save us all but OVM can actually solve licensing problems with Oracle RDBMS. It's one of the few on-prem solutions for which they allow sub-capacity licensing. I've pondered it but concluded that the extra time and energy spent dealing with it would exceed the the cost of just eating full capacity licensing.

You can also hire a firm to fight the oracle people in some kind of cage match situation which might also balance out $$$ wise, but yeah "this is the result of a licensing audit" is the only reason I've ever seen anyone using OVM.

wibble posted:Has anyone got experiance of Oracle Linux Virtualization Manager? We migrated from the XEN to KVM version last year and it's been a night and day improvement. It's currently running only our oracle apps and dbs. Good: Nicer interface and when you click things they are responsive. Easier to troubleshoot issues with the availability of KVM articles. Our Oracle admins are much healthier not having to worry about XEN related poo poo. Bad: You still have to deal with oracle licensing as you may have to pin servers to particular cores, and of course doesn't save you if a DBA uses a function you aren't licensed for. A lot of our tools we use to monitor to VMWare and other virtualization setups don't work with it of course. We had to start literally over with our OL servers though as none of our migration methods would keep thin provisioning working and we couldn't deal with 300GB OS disks. At least this helped me understand how cobol licensing worked ghostinmyshell fucked around with this message at 22:25 on Jun 27, 2022 |

So, if I was on the path to specialize as a virtualization/storage engineer with VMWare, I should move away from that since the Broadcom purchase? Also, I've got a three-node PowerEdge R320 cluster right now that I'm wondering whether it's worth it to upgrade CPU/RAM for better performance (I'm mostly doing cluster-based homelab stuff, so three identical nodes is what I'd like to keep) or, should I save and upgrade to DDR4-based systems? I haven't been following whether or not pricing for v3/v4 machines is coming down quickly or whether or not the supply chain is still an issue. I've done some of my own research already and I'm still on the fence whether I want to spend several hundred dollars on servers that are still using DDR3.

VMware has >75% market share for on-premises virtualisation and I doubt that even Broadcom can gently caress that up. Technology and feature-wise VMware remains the gold-standard and are the most unobjectionable choice. They've also got VMC (VMware Cloud, basically VMware-as-a-Service running on AWS) which seems somewhat popular as it makes setting up a "DR site" easier. So yeah, there's no reason why you shouldn't still specialise in VMware. However I would recommend that you also specialise in AWS and Azure virtualisation as "lift-and-shift" VMware engagements are increasingly common.

This is just bog standard capitalism hell world complaining. I dont have any love for VMware but they're the market leader and will stay the market leader barring unforeseen circumstances, if thats what you find fun go hog wild, comparisons to mainframes and Oracle are pretty disingenuous.

VMware is never required for any solution, rather it is chosen because you'd be laughed out of the room to choose anything else. Also I think you're confusing becoming familiar with a technology/product to further ones career with actively endorsing the technology/product.

I mean, you could read that blog post; you could read Broadcom’s investor PR about increasing revenue and reducing costs, or you could look at the trajectory of enterprise platforms (enterprise- not dominant tech companies; NVIDIA isn’t selling P100s and charging a subscription for cuda.) Their core products are stagnant in tech and in revenue. They may be dominant now, but IBM was dominant in the 80s and Oracle in the 00s. No CIO wants to pay Oracle or IBM or SAP, but they do, and they’ll pay Broadcom. It’s not going away, but I wouldn’t advise a generalist to investing in developing skills in it, because I personally think things that look like cost centers or have ongoing maintenance that aren’t tied to revenue are less valued by leadership and less compensated, particularly when there’s a fountain of cash for highly transferrable skills in other areas.

They literally do I deal with enterprise nvidia bullshit as part of my job https://www.nvidia.com/en-us/data-center/data-center-gpus/ Also doom and gloom about how broadcom will ruin them but tbh there isn't much to ruin, VMware hasn't been innovative in over a decade and it blew my mind reading that article that they had 40k employees. That doesn't change the fact there isn't a large market that they will hold for the foreseeable future, unless you think xenserver or proxmox are gonna take over (lol)

Hoping this is the right place: Is there a type-1 hypervisor I can deploy on a desktop and have it boot a specific VM / image automatically unless I hit some magic keys to get a console and deploy a new image / snapshot? I have a particularly troublesome client for whom steady-state software like Deep Freeze doesn't work due to some quirk of how Windows handles their device drivers, but I've managed to get it to play nice with VM pass-through. Now all I need is non-persistence and no way for them to gently caress with the host OS. Ideally I'd have them save their work to external and make the guest VM revert to snapshot on every boot. I found a couple reddit threads about this but the info was either old, thin or inconsistent.

I've pondered it but concluded that the extra time and energy spent dealing with it would exceed the the cost of just eating full capacity licensing. just build a separate vsphere/whatever hypervisor cluster off to the side and license those sockets. You don't need a separate vcenter or air gap despite what sales says and if you push back they'll eventually cave. Also they only license for allocated capacity in cloud providers too so that's an option as well.

Shumagorath posted:Hoping this is the right place: Hacky, but should be doable: Use KVM and passthrough the videocard and some usb controllers? Use something like ZFS to rollback the filesystem back to its original state whenever you start the VM. KVMs Qcow2 format probably has something as well. Set the VM to boot on OS host boot and it should work. A shell script should not be that difficult to build that checks for something before booting the VM. Otherwise you can always use SSH.

I wanted to play around with Proxmox before setting it up on a new machine, but I'm having some trouble with the networking configuration. On my Windows machine I created a VirtualBox VM as my playground for it, with a Bridged Adapter: Networking Config in Proxmox was then: That seems to work fine. Proxmox itself is able to get to the internet, and can ping my other devices on the network: Then I created a Debian VM in Proxmox with the following network device: Setup networking as follows in the Debian VM (I'm using a desktop environment here since I plan to run a GUI based app on it, accessed through VNC): However, this Debian VM isn't able to ping anything on the network, and can't get to the internet. Furthermore, my ability to use the Proxmox web interface seems to randomly cut out, and it will suddenly come back as soon as I ping 192.168.69.13 from my Windows machine...what's going on here?!

Did you edit the subnet mask after the last picture? I can imagine things starting to act wonky with an all zeroes subnet mask. Edit: Let's take a step back and clarify exactly what you want to happen here. Do you want the VM to behave as if it's a regular machine plugged into your network, do you want it to use NAT and have the Proxmox box act as its gateway, or do you want a new isolated subnet for that VM to live on? i.e. is the rest of your network 192.168.69.0 as well?

One thing that looked suspect to me was the CIDR for vmbr0 in the second picture. I'm not familiar with Proxmox, but I would have assumed it should be 192.168.69.13/24. It may be useful if you post the output from 'ip address' and 'ip route show'.

I ended up getting everything working when I tried it with real hardware rather than proxmox inside virtualbox. I'm pretty sure the subnet was where I was going wrong with the VirtualBox attempt. Here's what I ended up for the proxmox host network config: Then provisioned my Debian VM as follows: Left the Debian config as DHCP and then assigned it a static IP address from my router (Unifi) Everything is working great! SPICE is really cool, I had never heard of it before last week. I was running into an issue setting up VNC and came across NoMachine and SPICE while I was poking around. Proxmox had built in support for SPICE so I went with that. Auto-resize of guest display, support for audio, etc. Unfortunately it doesn't seem that shared folders is supported using virt-viewer for Wnidows when connecting to a Linux guest, not a big deal though. The performance seems great so far and I don't notice any difference between Proxmox+SPICE and VirtualBox as of yet. fletcher fucked around with this message at 22:08 on Aug 6, 2022 |

I’ve got a small Ubuntu home server running Home Assistant and a Unifi Controller under a creaky qemu/kvm setup, plus some other under-maintained services. I also have a Steam Deck which is shockingly compatible with the things I’ve been playing. I have virtualization questions about both arenas! For the home server, I think I’d like to get rid of the mini tower and move to a NUCish form factor, and beef it up so I can play with some more modern homelab/clustering things. My light reading has led me to a Simply NUC Ruby r8 on which I will stick proxmox and then figure out how I want containers and VMs to interplay. And then stub my face on k3s, probably. Is this a sane path to pursue? For gaming, the time for my Zen 4/Lovelace upgrade is coming and I’m seriously thinking of giving Linux gaming a shot for the first time since “Civ: Call to Power”. If it doesn’t work out for everything, I will probably want to do GPU+USB passthrough to Windows 11 or similar. Can I plausibly do that with a single NVIDIA GPU? I’ve heard tell, but I don’t know how reliable it is. What’s the state of the art for doing things like clipboard in/out of VMs? I’ve only used the VMware stuff for that, and I’d rather not entangle myself with their stack if I can avoid it. Thanks for any guidance you can provide!
