Does Azure provision on H-V under the hood or is it running some other hypervisor?

It's Hyper-V.

Microsoft is working on using linux on as the root partition for hyper-v https://www.theregister.com/2021/02/17/linux_as_root_partition_on_hyper_v/. Eventually Azure will be running linux on bare metal like every other cloud provider.

This might be too noobish for this thread, but here goes: Does anyone know of some architectural/system diagrams for virtualization technologies that would help classify some of these things in my mind? Like, I’m running RHEL8, and have KVM installed for my hypervisor. I assume it’s using qemu to emulate some different machine hardware. I’m using cockpit to manage most of it, which is the web front end for a bunch of command line tools and other tools like virsh, virtio, virt-manager (another ui), which are all part of libvirt…? Other hypervisors are included in different platforms that may include their own tools: Xen… virtualbox, VMware… Where does proxmox fit into all of this? Can I use qemu with xen? How about VMware? Will Virt-manager administer VirtualBox VMs? Am I missing any features by choosing kvm over xen? Or proxmox? These are just example questions… I’m mainly asking if there are any good articles, resources or diagrams that lay them all out so I can better answer them myself and understand the trade-offs and what’s compatible/competitor.

I don't know anything about Promox, but I was looking at it when it was mentioned earlier and it seems like they have a backup server as well. https://www.proxmox.com/en/proxmox-backup-server

The backup server is probably overkill for homelab but it can dump backups to any NFS share for example. The latest versions also do a nice staggered retention scheme thing

I just want to say that I love vagrant so much. I know containers are the new hotness but when I have to test our Ansible deployments and I can get a full VM up and running in a few minutes it rules. Spent today messing with triggers and I now get a RHEL box up and running and registered on first up and it removes itself when I destroy.

I can't tell if this is really basic and I'm missing something, or if there's something complicated I just don't understand, but I'm trying to create a few VLANs for different LAB networks in vSphere and use VyOS to route between them all. If I were doing this physically I'd plug everything into one switch, tag the switchports with VLANs and have VyOS with a trunk uplink and sub-VIF interfaces for each VLAN. For the life of me I can't gather how to accomplish the trunk to a single VyOS VM. I have a vSwitch and it has a number of networks attached to it, each with a different VLAN, but then when I set up VyOS VM I have to choose an actual network for each NIC, I can't just say form a trunk and I'll take care of the network routing myself. I feel like five years ago I would have known how to do this with my eyes closed and now I'm not even sure what to google :| e: Oh wait, do I just create a port group on that vSwitch with VLAN set to 4096 ALL and it'll partake in the traffic from the other portgroup/networks on that vswitch, than uplink the vyos guest to that portgroup some kinda jackal fucked around with this message at 23:38 on Jun 8, 2021 |

The question that prompted this got me thinking: I do wish there was a abstraction framework that could multiplex several hypervisors on the same hardware, when they all use hardware-accelerated virtualization (ie. VMENTER/VMEXIT with SLAT). As it is, when you've got one type-2 hypervisor running, you can only launch additional instances of that hypervisor. You can't, as an example, have bhyve, xen, and virtualbox interchangably, nor can you live migrate between them. In that sense it seems like there's still a lot of work to be done, but I think there's very little hope for an open standard for either the abstraction nor the API for live migration.

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. Wasn't Microsoft looking at using HyperV sandboxes by default for windows applications at some point? Not sure how that is supposed to work with other VM servers going. My understanding is that nested VT-d ("VMs inside VMs") actually does work properly so maybe the solution is to have Virtualbox register itself as a VM inside HyperV if it sees that HyperV is already installed. That seems like the "abstraction framework" we're seeking imo.

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.

You're thinking of Windows Defender Application Guard, which makes use of HyperV to sandbox quite a few things, including the Edge browser - it also underpins Windows Sandbox, I think.

Since version 6.0 VirtualBox has been able to use the "Windows Hypervisor Platform" on Win10 1803+ to be coexist with Hyper-V.

Hi thread. I have a windows 10 PC, 9900k, 2080ti, 32gb DDR4 ram. Is it feasible to use a VM so that I can have someone playing a VR game while someone else uses the screens to play a relatively low GPU/CPU demand game? Thanks. I've never done anything with VM before but I'm otherwise a pretty techy goon.

# ? Jul 16, 2021 00:13 |

Technically, you could do it without a VM. Nothing says you can't run two apps at the same time. I think your biggest hurdle might be separating inputs. Hard to tell something to use a keyboard in one app but not another. Same with mouse or controllers. Maybe someone else can think of a way.

It’s supported natively up to windows server 2016 as multipoint server, it was EoL on 2019 due to the introduction of azure desktops and windows 10 enterprise multi-session(formerly EVD). The biggest hurdle is that the 3D support might not be the best for games.

I've never done anything with VM before but I'm otherwise a pretty techy goon. It's cleaner if you do one discreet video card and usb controller per vm, for a while I booted fedora on intel igpu, windows 10 vm with a 2080 and a osx vm on a Rx 570 and I could use all 3 at once. It's also possible to share your 2080ti with multiple vms but you'd lose video out, you'd have to use a bunch of steamlinks or something for that. Now I proxmox because its basically built for edge cases like this.
