1) VM configuration.<br>
VM configurator on my laptop annoyingly sends complaints<br>
about "requested memory exceeds the limit..."<br>
so I changed parameters from Luis' 2 GB down to 768 MB and<br>
I also increased Video Memory up to 64 MB.<br>
<br></blockquote><div><br><br>Good point, I hesitated a lot with how much <=
br>RAM to allocate for the appliance.=C2=A0 I guess<br>that starting with a=
small RAM makes more<br>sense (and maybe adding a prominent notice<br>lett=
ing users know where they can increase<br>
the RAM in the Virtual Box setup).<br><br>Question: It is reasonable to exp=
ect that users<br>of the Virtual Appliance already know how to<br>configure=
its parameters (RAM, video... etc) ?<br><br>=C2=A0</div><blockquote class=

2) Host-Guest integration.<br>
Since I am a quite lazy man, I prefer Host-Guest<br>
full/partial integration that makes my life easier.<br>
<br>
Because Luis has installed dkms anyway, it's very easy<br>
to make one step further and install "Guest Additions".<br>
<br>
Make sure, however, you do not have any vbox* drivers<br>
already installed.<br>
<br>
itkuser at ITK-VirtualBox:~$ sudo rm /etc/init.d/vboxadd*<br>
itkuser at ITK-VirtualBox:~$ sudo rm /lib/modules/2.6.35-22-generic/updates/vb=
ox*<br>
<br>
And now you can mount "Guest Additions" iso and install them.<br>
<br>
itkuser at ITK-VirtualBox:~$ cd /media/VBOXADDITIONS_3.2.10_66523/<br>
itkuser at ITK-VirtualBox:/media/VBOXADDITIONS_3.2.10_66523$ sudo sh VBoxLinux=
Additions-x86.run<br>

<br>
4) "Security First".<br>
It immediately boots into Ubuntu session which I do not like at all.<br>
Thus, I disabled "Autologin".<br>
<br></blockquote><div><br><br>I thought on leaving auto login as a matter o=
f convenience,<br>but I see your point here.<br><br>=C2=A0</div><blockquote=

5) ITK Manual and README.<br>
It's nice to see the ITK handy info which sits right in front of you.<b=
r>
<br>
itkuser at ITK-VirtualBox:~$ more README.txt<br>
<br>
<br>
6) Clean the system.<br>
itkuser at ITK-VirtualBox:~$ sudo apt-get clean<br>
<br></blockquote><div><br><br>I'm curious about this step.<br>Did it re=
duced the size of the appliance ?<br><br>I confess that I have never done &=
quot;sudo apt-get clean"<br>so, it was interesting reading about it.<b=

Is that from Ubuntu repository or compiled by Luis?<br>
<br>
Lets clean the system and make sure that the version<br>
compiled by Luis gets installed.<br>

Kudos Luis Ibanez,<br>
the creator of a Virtual Appliance with a pre-installed ITK!<br>
<br>
The system is fully operational and very easy to use.<br>
<br>
Thanks for this Virtual Appliance,<br>
