I had problems with Nexenta2 beta with QEMU and KVM, but then I tried VirtualBox, and it worked! For me, Nexenta2 works with VirtualBox. Hooray!

So far, it doesn’t seem too much different than the stable elatta version 1 of Nexenta.

I’m running it headless, so I used this command:

VBoxHeadless -s nexenta &

rather than using the VirtualBox GUI.

This is not a new discovery to me, I’ve known that pfSense is an amazing resource. I’m posting this to make sure that other people know this as well.

I’ve been using pfSense for about 3 years now, and I use it everyday. It is part of my company’s infrastructure, as firewalls, IPSec VPN gateways, a DHCP server, and a NAT tool.

If you have considered using pfSense but haven’t gotten around to it yet, take my positive experience into consideration. You might like it as much as I do!

FreeBSD Jail Confusion

I’m confused about a FreeBSD jail I’ve setup. I’m using the ultradesic minichroot.sh script to enter the jail, but it doesn’t seem to affect what’s happening. I run a kldstat (kind of like lsmod in linux) in the host environment, and get this output:

# kldstat
Id Refs Address    Size     Name
 1    7 0xc0400000 906518   kernel
 2    1 0xc0d07000 6a32c    acpi.ko
 3    1 0xc1d8a000 22000    linux.ko

And then I enter the jail and do the same thing:

# ./minichroot.sh /usr/jail6
MiniBSD6 / # kldstat
Id Refs Address    Size     Name
kldstat: can't stat file id 1: Invalid argument
kldstat: can't stat file id 2: Invalid argument
kldstat: can't stat file id 3: Invalid argument

I wouldn’t be bothering with this, but I’m trying to mount a disk image:

MiniBSD6 / # mdconfig -a -t malloc -s 1m
mdconfig: failed to load geom_md module: No such file or directory

Doh!
