Readers Ask About ... Virtualization of Services 1
Below is the 2nd of 6 questions from a reader. I definitely don’t have all the answers, but I’m not short on opinion. ;)
Part 1 – LVM+JFS+RAID | Part 2 – Service Virtualization | Part 3 – Virtualizing Media Storage | Part 4 – Hosting Email

Q2: I read everywhere about Virtualisation, should I directly install packages to the base system to provide services, or should I virtualise all services? What are the advantages here?
Advantages of Virtualization
The list of advantages is long, but with those advantages comes a few disadvantages. I cannot hope to point out all the advantages, so I’ll limit it to just the main ones.
Diagram of Linux Distro History
A picture is worth …. 1,000,000 words in this case.
This link shows the way that different distributions are related, started, and some died. It only shows the most popular distros, perhaps 300 of them. I didn’t count.
VMware Hiding the vSphere Client
Where to download the latest vSphere Client?
I just spent the last 90 minutes hunting the vmware.com web site for the latest x64 Windows7 vSphere client. VMware has lots of things you can download prominently displayed … just not the latest vsphere client.
It still bothers me that I’m required to run MS-Windows to use the mandatory client.
In the end, I had to select a new download of ESXi, agree to give my first born to them, sign a contract, then they showed a list of about 5 more downloads – including the damn vsphere client that I wanted. While I was there, I grabbed the 4.0 to 4.1 ESXi upgrade package.
For the last 2 years, ESXi has been rock solid … until about 10 days ago. That’s when a 32-bit Linux VPN server stopped responding. The other machines are available and working, just that one is not. Got an error trying to use the v4.0 vsphere client to connect.
The error that the old vsphere client, v4.x, displayed was error parsing clients.xml This error happened on both x64 and x32 machines running either Win7 or WinXP. Basically, only the unsupported ssh login was available. According to the google results, a new vsphere client will fix everything. I hope it does.
I can’t wait for KVM to be as good.
