I never tried VMF so it may be faster, sure. The thing about VBox is, like I wrote, features. VBox is basically a full-featured Virtualization-Suite, has multiple UIs and an API. It is also available on Win7,8,10/macOS/Linux and Solaris.

You may add: excellent documentation and friendly support (board, irc, list).

If I'll ever have to switch, I'd first need feature-parity.

better than Virtualbox

Just take a look at VBoxManage --help for a crazy list of settings and features that VBox has accumulated during the past ~10 years.

It even supports ATA TRIM so your fs-driver can discard blocks and keep the VDI-file deflated at all times.

Performance-wise: Compiling stuff within VBox on an i7 quad-core (-j5) is almost as fast as native. X on Linux-VMs feels native too, especially when running in fullscreen.

Bridging to a wireless interface is done differently from bridging to a wired interface, because most wireless adapters do not support promiscuous mode. All traffic has to use the MAC address of the host's wireless adapter, and therefore VirtualBox needs to replace the source MAC address in the Ethernet header of an outgoing packet to make sure the reply will be sent to the host interface. When VirtualBox sees an incoming packet with a destination IP address that belongs to one of the virtual machine adapters it replaces the destination MAC address in the Ethernet header with the VM adapter's MAC address and passes it on. VirtualBox examines ARP and DHCP packets in order to learn the IP addresses of virtual machines.

So what? Many standards originated from some particular need of one or two companies popular at that time. Look at the current IETF WGs and the authors of the drafts they produce.

but the only commentary it seems to offer is by Vietcong themselves

Yeah, nobody cares about the point of view of a 60kg Vietcong soldier. They are not supposed to have a face and keep quiet beneath that 2+ million bodycount. The brave war stories are reserved for the american GIs.. and hollywood.

> This is the fourth time in the last 30 days I have seen some blog post about DNSSEC on the front page. Three overtly pushing Cloudflare DNSSEC and one about email and DNSSEC written by a Cloudflare employee.

Absolutely, this is getting out of hand.

Would be easier to just buy HN and replace all top stories with your crappy DNSSEC ads..

> this server was configured perfectly: (...) SPF, DKIM and DMARC policies in place

SPF, DKIM and DMARC are no indicators of spamminess of a source. These systems have a completely different purpose.
