This makes me consider using VirtualBox again. Having to install and update a kernel module is annoying. Especially on some immutable/image-based distros like Fedora Atomic.

Re: VirtualBox KVM Public Release
#152Earlier quoted context omitted.
I wouldn't call it kernel based. It's not like this is an in-kernel emulation. I would stick with hardware virtualization. KVM is a userspace API, and kvm-intel/kvm-amd are the drivers for the hardware. You will be using hardware features. That's also why it is in the kernel: nothing but the kernel should have full unlimited access to the CPU to set this up. So you could say it must be in kernel to keep the kernel se…
if in the past they already were using a kernel module then your reply doesn't explain anything. So they went from using hardware virtualization (provided by intel/amd) with their kernel module to the KVM one. I don't know which benefits it brings
Without being at all up to date on the current state of things, the Virtual Box third party kernel module was historically of famously poor quality[1], even putting aside the general pains of third-party kernel modules.

#153I'm quite inexperienced with Virtualization. Are there benefits to kernel based virtual machines beyond (what I assume is the primary benefit) performance?

there's no "keeping the kernel secure" and "allowing access to the hardware".
in security research, you either run your samples in qemu without even kvm or you don't.
Re: VirtualBox KVM Public Release
#154Why? How does this generate revenue for CyberusTech? What is the long term goal?
Those are good questions. I don’t understand why you were downvoted. To answer: We are offering service contracts and contract engineering services around virtualization, KVM and a couple of other topics. The long term goal for this specific project is to support the security goals our customers have and to enable a couple of KVM features in Virtualbox as well. We plan to keep this updated with upstream Virtualbox an…
so, the plan is to take on docker hub?
edit: nevermind. i assumed you were a team inside oracle.

This would be useful for anyone who needs to run bleeding edge linux kernels. Most other hypervisors have poor support when you're pinned to testing distros (For security reasons). KVM and virt-manager are uh not exactly user friendly, so being able to use the KVM backend and always be compatible with the new kernels while having the UX and UI of vbox is actually a very huge deal. This is one of the main reasons I re…
That's odd about the core count. I only get that behavior if my host system only has 1 CPU to begin with (tested in qemu/KVM with nesting). Could you comment on your host system parameters a bit?
This is definitively not expected. You could also try setting the CPU/Mem configuration via VBoxManage. Maybe you get a good error message then.
`VBoxManage modifyvm --cpus `
`VBoxManage modifyvm --memory `
Re: VirtualBox KVM Public Release
#156Reminds me of the bad old days when I regularly had to open a crappy windows 7 in a VM because some minor piece of software would not run on Linux or on the browser. Thankfully I haven't needed to do that in years. On a more constructive note, this might be really useful for kernel developers, and for big companies using desktop virtualization.
Crappy? Windows 7 was the last good Windows.
You don't like being plastered with ads and news articles about Trump every time you open your start menu??
Re: VirtualBox KVM Public Release
#157I'm running a Ryzen5600G on Arch and recently switched from VirbualBox to QEMU/KVM and couldn't be happier. Webcam, USB drives, Hardware Video Acceleration, all working without issue (after a pretty tough learning curve getting it set up).
Yes, I recently had to compile some stuff on Windows (I'm on an AMD Linux host) and VirtualBox just wouldn't start Microsoft's Windows dev VM (the one they provide for free for Virtualbox). I ended up learning how to use qemu and it works great...and as a bonus I was able to run a hackintosh (via https://github.com/kholia/OSX-KVM) and it works near flawlessly, which was something I was never able to accomplish with Virtualbox (granted I haven't tried in a few years).
I'm pretty happy with Qemu now, even if it's jsut a CLI interface. I was tempted to try the virt-* stuff, but honestly it seems like one more thing to learn so I'm going to hold off until I need something like copy/paste between VMs and can't figure it out in qemu direct.

#158Earlier quoted context omitted.
Virtual box has graphical configuration for a ton of different options. It also “just works” in many cases and is relatively easy to use. I am surprised the open source community has not built better gui tools, and no project, closed or open has made configuring pcie passthrough easy. I have always wanted to be able to run Windows in a virtualized session with my GPU for gaming, and use my onboard APU for the Linux h…
I wish there was a port of UTM to linux
Gnome Boxes is an attempt at a similar interface, but yeah, it's not quite as polished.
Re: VirtualBox KVM Public Release
#159Finally! Every time I need to run a virtual machine, I choose libvirt because it's more performant and easy to deal with than Virtualbox (no kernel module, etc.), but the GUI choices are pretty terrible. The "best" libvirt GUI is virt-manager and it's very, very buggy and lacking features (i.e. doesn't play nice with HiDPI screens, no way of configuring IPv6, etc.) Many times I have caved and chosen VirtualBox simply…
Regarding IPv6, there is support. In fact I run IPv6 only networks including for the hypervisors.
$ virsh net-dumpxml default6

At a previous employer Oracle sent a nastygram because they saw downloads of the VirtualBox extensions pack (which is free to download, but requires a license) coming from our IP block. This despite the fact that we were a big Oracle customer (tons of Oracle DBs; granted, we hadn't purchased VirtualBox licenses). I'd rather not deal with a vendor that's that antagonistic.
> This despite^H^H^H^H^H because of the fact that we were a big Oracle customer FTFY. Having spent time at another large Oracle customer that was later acquired by Oracle I've seen how they do this internally too. And you can't just send it off to Legal to write back that "we didn't actually use it"...
This employer has a massive network with a bunch of guest networks (it's a hospital chain), so I thought they could just say there was no way to know whether it was employees or not. Of course, IIRC they just paid the ransom and added new restrictions on how employees could manage their work machines.
