Dear OpenNebula Team,
I want to download OpenNebula and see there are options like OpenNebula
3.2.1 Ubuntu 10.0.4 amd64 and OpenNebula 3.2.1 CentOS 6.0 x86_64.
For OpenNebula 3.2.1 Ubuntu 10.0.4 amd64, we have to buy AMD processor, but
for OpenNebula 3.2.1 CentOS 6.0 x86_64, what type of processor should we
buy?
Thanks,
Q.S.
Just becuase the kernel name says "amd64" in it doesn't mean that
the kernel can only run on AMD processors--it is the Ubuntu way of
designating the "64-bit" extensions of the x86 architecture which
were first done by AMD and shortly afterwards by Intel. "amd64" packaging
can run on either one.
CentOS "x86_64" kernel can run on either processor AMD or Intel too. For
my money I would buy the Intel, my experience shows that the
intel southbridge and chipsets play better with virtualization
particularly with networking.
Also see what the others said about checking the compatibility flags
in /proc/cpuinfo.
