rPath says “VMware is worth $17M”

http://billyonopensource.blogspot.com/2007/08/vmware-ipo-sizzle.html

VMware is worth $17B because their technology enables the dream of utility (or grid) computing. By eliminating the operating system as a bottleneck for attaching applications to computers, applications can now run flawlessly on any computer that has the VMware hypervisor as the bottom layer — with no expert resources required for testing, porting, stabilization, etc.

MEMSET virtual web hosting

I'm now trying MEMSET virtual web hosting and its looking very good so far.

WHM/CPANEL has changed (improved) a lot since I last used it two years ago (when I defected to Plesk).

Not only does the MEMSET reseller package give you ssh root access to your VM you also get ability to update Fantastico yourself and update key system packages such as wget !

If fact the very first thing you have do using WHM (and by ssh as root) is update wget 

# rpm -qa wget ;
# wget ftp://fr2.rpmfind.net/linux/fedora/core/5/i386/os/Fedora/RPMS/wget-1.10.2-3.2.1.i386.rpm ;
# rpm -e wget ;
# rpm -ivh --force wget-1.10.2-3.2.1.i386.rpm ;
# rpm -qa wget ;

and then update Fantastico !

Not for VM webhost beginners then but power equals complexity !

kernel virtual machine (kvm) virtualisation

There is yet another virtualisation technology on the block !

http://www.vizzr.info/2007/04/24/kernel-virtual-machine-kvm/

kvm only run on processors that supports x86 hvm (vt/svm instructions set) whereas Xen also allows running modified operating systems on non-hvm x86 processors using a technique called paravirtualization. kvm does not support paravirtualization for cpu but may support paravirtualization for device drivers to improve I/O performance.
kvm FAQ

Proprietary vendors take note :
Xen and kvm make use of Intel-VT and AMD-V hardware virtualisation features !

VMware Server & VMware Player combo

VMware Server and VMware Player are a great combination.

I've just built a VM on a Server host copied it to a Player host and just used VMware tools to shrink the guest VMDK from 3.2G to 1.4G ! Did Player always do this ?

W2K installation process

Unfortunately I just had a requirement (need to run an EXE that creates a BIOS update floppy) for a W2K virtual machine. I haven't built one from scratch for over four years. Here's the sequence I used on a VMware Server guest in case I need to do it again in another four years !

Install

  • W2K Professional
  • W2K SP4 (reboot)
  • Install VMware tools (reboot)
  • Uninstall Outlook Express
  • Uninstall Indexing Service
  • IE6 (Windows update is broken in W2K IE5) (reboot)
  • Windows Update (Why does it insist on patching Outlook Express even thou I've uninstalled it ?)
  • Sun Java JVM

Defrag
Shrink VMDK by 50% (with VMware tools from 3.2G to 1.6G)
Backup (tgz w2k.tgz /vmfs/w2k)

W2K is now ready for action ! Lucky I still have one PC with a floppy disk !
