Description Andrew Cathrow 2010-06-01 23:54:28 EDT
(From Fujitsu)

In chapter 3 under "KVM restrictions and support" we have the following line 

"The Red Hat Enterprise Linux kvm package is limited to 16 processor cores in Red Hat Enterprise Linux 5.4 and newer"

This is incorrect. KVM supports 16 virtual CPUs per guest, but the limit of processor cores in the host is higher.

This was reported by Fujitsu who thought this meant that the host was limited to 16 cores. we need to tighten up the language.

>>but the limit of processor cores in the host is higher.

NEEDINFO to find out the actual limit of processor cores if this is to be fixed by 5.6.
