I am a member of the Cult of vi. The
Vim variant, to be precise. So, when I fire up a terminal session on XenServer... I always feel a bit lost and confused because the vi editor in XenServer does not behave like Vim, at all.
So, whenever I setup a new XenServer host, I always do the following.Read More »
If your environment is like many Enterprise environments, you most likely won't have direct access to the Internet. Everything must go through a proxy.
Thus, you might think that the only way to create Ubuntu VMs on XenServer is by using a previously-downloaded .iso file, since the XenCenter GUI does not provide a way to specify the proxy through which XenServer pulls in the requisite images.
There is a way, though.Read More »
It's amazing how many hoops and loops I had to go through to create a relative reference that 'survives' table row inserts/deletes in Excel.
Let's say, for example, I have a table whose "C" column is a row of differences, like this:
and so on...
Then I delete row 7. What will happen? The new rows 7, 8, and so on will all display
#REF! errors!. And if I do an insert instead... well, best of British luck for me trying to fix all the errors.
Earlier, I've questioned the stability of XenServer 6.2.0 on Dell PowerEdge R815 servers. Is the instability caused by an unholy interaction between the R815 and XS6.2.0, or is it caused by a general instability of XS6.2.0?
After some discussion with my team, we decided to do some experimentation with the Dell PowerEdge R815 server.
You see, one of my team members tried to install XenServer 6.2.0 on an HP ProLiant DL360 G5 last Friday... and it has proved itself to be stable until now.
So, naturally, the 'blame' lies on the Dell R815 server. What could it be?Read More »

So, +Erick Gafar, a G+Friend of mine once shared about Google's trialling out a city-wide WiFi hotspots network in Jakarta. This service is officially called WiFi Passport powered by Google.
What is it about, actually?Read More »
Windows, since XP to be exact, requires "activation". That, on itself, is just a minor annoyance.
The problem is when the computer(s) needing activation is (1) stuck behind the corporate firewall, (2) can only access the Internet via a proxy, and (3) the proxy needs authentication.Read More »
If you need to migrate a Guest VM to a different XenServer Pool, one way to do it is to export the VM to a temporary location, then import the VM from that location into the target Pool.
Problem is, it seems that (on XenServer 6.1.0, at least) the Management Interface has been hard-limited to transfer data only at a rate of 100 Mbps.Read More »
