Well, it is part of CentOS 6 (64-bit only):

sauron.deepsoft.com% dir /centos64*/*/*/*kvm*
/centos64x86_64/1/Packages/qemu-kvm-0.12.1.2-2.355.el6.x86_64.rpm
/centos64x86_64/1/Packages/qemu-kvm-tools-0.12.1.2-2.355.el6.x86_64.rpm

I would guess it is in 64-bit Fedora and there probably srpms available that 
could be rpmbuild to suit.

I suspect that most (all?) modern multi-core 64-processors would support KVM, 
but I don't know for sure:

sauron.deepsoft.com% egrep -c '(vmx|svm)' /proc/cpuinfo
4
sauron.deepsoft.com% head /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 16
model           : 4
model name      : AMD Phenom(tm) II X4 945 Processor
stepping        : 3
cpu MHz         : 3348.594
cache size      : 512 KB
physical id     : 0
siblings        : 1

newserver.wendellfreelibrary.org%  egrep -c '(vmx|svm)' /proc/cpuinfo
2
newserver.wendellfreelibrary.org% head /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 60
model name      : Intel(R) Pentium(R) CPU G3220 @ 3.00GHz
stepping        : 3
cpu MHz         : 800.000
cache size      : 3072 KB
physical id     : 0
siblings        : 2

sauron.deepsoft.com is running CentOS 5 and xen,
newserver.wendellfreelibrary.org is running CentOS 6 and kvm.  Both systems 
have at least one Ubuntu VM installed.  The Ubuntu VM running on newserver 
runs 24/7 and is a server itself (tftp and nfs).  The Ubuntu VMs on 
sauron.deepsoft.com are only used as build boxes and are only run on an 
as-needed basis (eg when I need build something for Ubuntu).

I suspect that when I upgrade sauron to CentOS 6 (I am in no hurry to do so), 
it will happily run KVM.  (Or by that time I may have upgraded to newer 
hardware -- the future is so hard to predict...)
