VCP, Kindle and the thrill of finding the perfect place for awesome technology

Thursday, January 27th, 2011

The next few weeks I will be in study mode.
Next week a 5 day classroom course for VMware vSphere 4.1: Install, Configure & Manage
The week after that its 3 days VMware vSphere 4: Manage for Performance
Then some exam training and on the 25th the VCP4 exam. I am exited and nervous, as I have not studies for an exam or cert for a long time. But I am also confident as I understand a lot of the material already.

In preparation for this I have been gathering some white papers, been reading up on some things and have also been looking for a good book also. I was in the tram today paging through the Kindle app for the Android, and it struck me that the Amazon sphere would be the right place to consume this kind of stuff.  I have the Kindle app on my Ipad, my Phone and on 2 PC’s (I don’t yet own an actual Kindle) and the fact that I can pick up wherever I left off, wherever I am and when I have some time spare, appealed to me.

It’s a relief that I can actually find a good use for all these kindle outputs because I was stuck in the dilemma between the physical and the virtual. I will soon be receiving my first leather bound book from Easton Press, but for a while I felt torn between the superior convenience of ebooks, and the wish to have a proper physical book collection. But I realize now I can split the difference; educational books work a lot better as ebooks. So I can find good an honest use for both the old and new at the same time.  This is greatly fulfilling to me somehow.  I now even have a reason to get a Kindle.. perhaps.

Still in the tram I bought Scott Lowe’s Mastering VSphere 4, Kindle edition, and directed Amazon to send it to all my devices. By the time I got home, it was already downloaded onto my Ipad.


I used to collect a large amount of the MSPress books, but was saddened when I realized that most of them would become obsolete. Getting the ebook versions of these kinds of books might not necessarily be that much cheaper (mastering VSphere 4 set me back $41), but at least its not a waste of paper!
For a long time I justified buying these books by saying that I would rather read from my hand that from the screen, and this is actually true. But The Ipad and Kindle are convenient enough (and even my Android phone is, to be honest), that I cant justify wasting the trees on this kind of book anymore.

I was also thrilled to discover that some of the old Battletech novels are being re-released as Kindle versions. It was impossible to get your hands on, for example, the Blood of Kerensky trilogy in paperback form, it has been out of print for so long. I read most of the novels until Darkage started, but I never got my hands on some of the oldest titles. I hope they bring them all back! What a rich universe to re-discover!

“Multiple Connections” error when importing a Physical machine into VMware

Wednesday, November 4th, 2009


As many before us, we ran into the following error in Virtual Center, when we tried to P-to-V a server:

“multiple connections to a server or shared resource by the same user”

This is not an uncommon error, and you might recognise it from other scenarios that involve remotely connecting to a Windows host. 
I found quite a few posts that mentioned this problem, even a mention in the release notes of VMWare Converter itself, and an VMware knowledge base article,  and they go something like this:

An Inter-Process Communication (IPC) named-pipe network connection is already open from the local Windows Redirector to the remote host with different credentials than you are specifying in Converter. The Windows Redirector does not allow IPC connections with multiple different credentials from the same user session. This restriction also applies to mapped network drives as they are also a type of named-pipe connection.

To ensure the Converter agent connection succeeds, perform the following actions on the computer running Converter:

  1. Close any application views or Windows Explorer windows showing files, ActiveX components, or Microsoft Management Console (MMC) snap-ins from the server you are trying to convert.
  2. Open a command prompt. For more information, see Opening a command or shell prompt (1003892).
  3. Type net use \\<remote_hostname>\ * /delete and press Enter.

    : This disconnects any mapped drives to the remote host.

  4. Check My Computer for any mapped network drives to the remote host and disconnect them.
  5. Log off the server running Converter and log on again.  This disconnects an open IPC named-pipe connections established by any remaining applications.
  6. If the problem persists, restart the server running Converter.
  7. If the problem still persists, and you are using the VirtualCenter Converter plug-in, restart the VirtualCenter server.

So we tried all the above, but to no avail. Try as we may, from both our admin workstations, aswell as on the Virtual Center server itself, we could not get it to run.

In the end, my collegue tried to run the task using the IP adress of the server, itstead of its hostname!

That did the trick! But don’t ask me why! I suspect it has something to with the named-pipe actually being named differently when you do this.
