Access VirtualBox guests from host and vice versa
In order to communicate between your VM's and host, add a host-only network adapter on the VM properties. The IP associated with this adapter will be reachable by the host.

Useful commands for checking Linux hardware specs - memory, CPU, serial number
Server model
# dmidecode | grep -A3 '^System Information'
CPU model
# cat /proc/cpuinfo | grep 'model name' | uniq
Memory summary
# dmidecode -t 17 | grep MB
CPU config - good summary, check socket and core outputs for physicals
# lscpu
CPU config - more detail
# less /proc/cpuinfo
CPU config - just the number of cores, physical and virtual
# nproc
Serial number
# dmidecode -s system-serial-number
# dmidecode | grep Serial
If no root / sudo access (might not work on Debian-based distros, tested on RHEL)
$ lshal | grep system.hardware.serial
# dmidecode | grep -A3 '^System Information'
CPU model
# cat /proc/cpuinfo | grep 'model name' | uniq
Memory summary
# dmidecode -t 17 | grep MB
CPU config - good summary, check socket and core outputs for physicals
# lscpu
CPU config - more detail
# less /proc/cpuinfo
CPU config - just the number of cores, physical and virtual
# nproc
Serial number
# dmidecode -s system-serial-number
# dmidecode | grep Serial
If no root / sudo access (might not work on Debian-based distros, tested on RHEL)
$ lshal | grep system.hardware.serial

Logitech Z323 Speaker Hints
Having purchased my Z323's somewhat hastily and without any prior consultation of reviews a couple of weeks back, I was somewhat underwhelmed by their output. I purchased them to connect to my PC for listening to a variety of music types in my small study, and it just seemed like there was a big chunk of frequency reproduction missing somewhere in the midrange. I'm currently into emo'ish instrumental pop/rock and trancey stuff, which is admittedly quite acoustically demanding.
Bass was ok, not exactly punchy, but nevertheless adequate. Overall, there just seemed to be an absence of "snap" in the audio reproduction. The last set of 2.1's I bought was many years ago (Creative Cambridge Soundworks 2.1) and the Logitechs just didn't seem to measure up to that aged benchmark.
I've not had much time to spend with my new acquisition, but after some tweaking this afternoon the following facts became apparent:
- The midrange does seem to improve after some breaking in (my set is only now going into the first couple of hours of sustained playback and seems to be becoming a bit more "flexible" as time passes).
- One of the reviews on Amazon.com recommended turning the sats around to face the wall - this made a big difference to the perceived audio reproduction. There is a sweet spot here, but if your desk faces a wall and you have these speakers give it a go and see. Disadvantage is that the speaker volume control is now facing away from you, but I can live with that.
- Stereo imaging is good with a very broad field - seems you can put the sats almost anywhere and still maintain a nice soundstage.
- Moving the sub down to the floor and closer to the wall made the bass a bit more generalised, but now it seems to have difficulty keeping up. I can hear it lazily whoomping away, but seems to be a bit laboured. Maybe this will also improve with time and some more fine tuning of location. Turning the bass dial down a few notches helped - there is almost an exact point at which it goes from nicely accompanying the music to becoming "whoompy", for want of a better word...
I suppose my expectations here exceeded my budget, but Logitech speakers generally seem to be reasonably good all rounders. Definitely happier now than before, hopefully this info is useful to somebody else out there as well :-).
