The truth about (Solaris and) Xen

Why is Solaris not good enough to act as a hypervisor requiring Sun to ship Xen in xVM?

via Tales of a Code Monkey

Because what used to be Sun didn’t suffer from the NIH syndrome that seems to haunt Linux developers. And while Linux may one day dominate everything, this doesn’t necessarily mean that it’s the best thing since sliced bread the same way that x86 is not. It will just mean that the market dynamics would have won.

Till then I am thankful that contrary to RedHat some people still appreciate that KVM is an emerging technology and Xen the leading FOSS virtualization solution. Thanks to them I can happily type uptime:

# cat /etc/release
Solaris 10 10/09 s10x_u8wos_08a X86
Copyright 2009 Sun Microsystems, Inc. All Rights Reserved.
Use is subject to license terms.
Assembled 16 September 2009
# uptime
9:46pm up 1:10, 1 user, load average: 1.14, 1.98, 2.19

and get consistently low load average utilization in my Solaris VM rather than in excess of 15, like I did with KVM.
