Ooops. Will fix. :) Thanks!
That's already b0rken in the Oracle sources.
Oops. I probably should have checked before mentioning it anyway. ;)

The out-of-the-box performance of Windows in VirtualBox is very good and usually better than virt-manager (Qemu). You can tune Qemu to great performance as well, but it takes some fiddling. VirtualBox is in general very user friendly. Guest integration (drag'n'drop, clipboard), USB passhthrough and audio support is also top-notch in VBox.
Until you want to pass a GPU to the VM
With this version of VBox, it's quite possble to pass a GPU to the VM. Have a look at https://www.cyberus-technology.de/products/hypervisor if you want to see a demo.
Re: VirtualBox KVM Public Release
#93Finally! 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…
virt-manager plays fine with hidpi on Wayland. On the opposite side, VirtualBox’s GUI is super buggy in Wayland.
It’s basically the opposite for both. I use virt-manager because the GUI is simpler (and setting up virtualbox is a nightmare anyway).
Regardless, this feature is a step in the right direction. I’m wondering if distributions will pick it up or if it will ever be integrated upstream.

If you don't mind, I have a specific question regarding this setup. I've been looking into getting into pentesting, mostly for fun. I decided on messing around with HackTheBox as a starting point. Seeing as you need to connect to their VPN, it seems like a good idea to me to separate this activity from my personal network. Which networking setup do you use for your pentesting VM? Ideally, I'd want a setup where the V…
You can probably do this for VirtualBox (and any Linux program) by using tun2socks to create a network interface that routes through a proxy (SOCKS5 if you want UDP support), and then moving that network interface to a new namespace. You can run VirtualBox or any other programs in that new namespace, they don't have to be aware of the proxy at all (since they just see a regular gateway). https://github.com/xjasonlyu/…
Which namespace are you taking about? cgroups_namespaces(7)?
Re: VirtualBox KVM Public Release
#95I'm quite inexperienced with Virtualization. Are there benefits to kernel based virtual machines beyond (what I assume is the primary benefit) performance?
You can’t use virtualbox’s kernel module and kvm at the same time. This basically means that you can’t use virtualbox and qemu at the same time.
If you use virtualbox with this new backend, you can use it concurrently with qemu (and a few other virtualisation tools).
KVM is also part of Linux itself, so there’s a lot less haste with setting it up.

Is there a connection to User Mode Linux (UML) from around the same time? Or are these completely unrelated projects? I get that running a kernel in the user space provided by another kernel is not really the same as a proper hypervisor, but have never really dug deep into why and what the various tradeoffs are.
There is no real connection to UML here. Hardware virtualization (Intel VT, AMD-V) are much faster in practice and also don't require the guest operating system to be heavily modified. So besides as curiosity or test vehicle, approaches like UML are pretty dead.
Thanks.
So, slow as it may be, the win for UML (which seems to still have a heartbeat) is that it can run on uP without any specific virtualisation capabilities, right? If I could run Linux on a Z80/6502 then in theory I could run a virtualised Linux on a Z80/6502.

#97Why? How does this generate revenue for CyberusTech? What is the long term goal?
Re: VirtualBox KVM Public Release
#98What took so long? Isn't this like 15 years late? How do people even use the thing without KVM?
KVM is the one built into Linux. VBox has it's own module for hardware virtualization all along
Re: VirtualBox KVM Public Release
#99Any chance this gets upstreamed?
I’d actually much, much rather see it set up as a proper fork (rebranded etc.), and then the features that Oracle extorts people with in the “free” but not actually free extension pack (like USB pass through) re-implemented and included directly with no ‘extension’ required. Much of the reason I refuse to use Virtualbox for anything is how scummy Oracle is.
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.
Re: VirtualBox KVM Public Release
#100So this basically turns VirtualBox into a replacement for virt-manager and virsh? AFAIK VirtualBox does not support PCI passthrough (like GPU), how is this case handled? Since I've moved to QEMU/KVM on Linux I've never looked back at VirtualBox, but I use the latter on Windows and there I'm always remembered of how much nicer and friendlier the GUI is. Edit: I just noticed that VirtualBox has experimental PCI passthr…
Please evaluate the license of the extension package carefully before using!
And don't download it from your employer's network if Oracle thinks they might have deep pockets.
