10 Gbit/s virtual wire speed in VirtualBox 4.2.16
I updated my FreeBSD 10.0-CURRENT virtual machine today. It reached r255120 and it’s running with vtnet as its virtual network interface under VirtualBox 4.2.16. I noticed the vtnet0 interface gained 10 Gbit/s virtual wire speed. Previously the interface ran with only 1 Gbit/s virtual wire speed. The actual wire speed depends largely on the physical limitations of […]

I’ve put WITH_ICONV=yes in my /etc/src.conf file on a few VMs running stable/9, and yes, I got burned. My beloved server named enterprise running stable/9 was also affected. :-/

I’m following this thread with great interest, and I wanted to try bootparttest on one of my own computers.

I upgraded some of my virtual machines during my summer holiday. They are all running ZFS, but were neglected for so long that they were still updating their source and ports trees using CVSup. I began pondering how to migrate to Subversion with the least fuzz possible. Luckily, I had anticipated the switch to Subversion, […]

I’ve been experimenting with FreeBSD 10.0-CURRENT and an alternative ZFS layout for more than a year. The idea is to have a simple way of switching between boot environments. Thus, you have the opportunity of reverting to a previous boot environment without resorting to snapshots and rollbacks as you would with a sole boot environment. […]

FreeBSD is approaching 20 years! I guess it all depends on what you regard as FreeBSD’s true birth. The baptism, the first commit to the CVS repository, the first release, or something else? The first commit to the CVS repository was done on “Sat Jun 12 14:49:13 1993 UTC”. That’s 20 years and 6 days […]

If you store files in the root file system of a zpool, it’s probably not so straightforward to access them from a different system, e.g. a live CD/DVD. Don’t panic. Here’s how.

I’ve been experimenting with carp(4) on FreeBSD/i386 10.0-CURRENT and FreeBSD/amd64 10.0-CURRENT for the past year or so. carp(4) is no longer a pseudo-interface, but rather accessible on every conceivable interface.

Today, I decided to upgrade PostgreSQL from 9.1.5 to 9.2.0 on one of my computers. Ironically, PostgreSQL 9.2.1 was released today, but until the FreeBSD ports hierarchy catches up, the most recent version available is 9.2.0, unless of course you want to do everything yourself.
