kvm is basically qemu.
The kvm launcher is (by default) not in your path:
/usr/libexec/qemu-kvm
request help on qemu-kvm and you will see almost the same thing which is in
qemu.
Trying to learn kvm via libvirt is over-kill - stick with the commandline.
You'll never need to run it from the command line, use the available
management tools (libvirt+virsh from the command line,
libvirt+virt-manager from X11), it makes your life much much easier.
I've been running qemu-kvm from the command line for several years,
and while it's fine to know how the system works, then you definitely
don't want to manage your enterprise virtual machines that way. For
example, if you start qemu-kvm twice in parallel, with the same HDD
image, you'll damage or destroy your HDD image. Libvirt takes care of
such banalities and many others.
Fedora 13 Live CD:
qemu-kvm -cdrom ./Fedora-13-i686-Live-XFCE.iso -boot d -m 384 -net
nic,model=rtl8139 -localtime -usb
Froze up at automatic boot in 10 seconds. This is probably because my
CentOS 5.5 is 32 bit and I am running a really old version of qemu-kvm.
No, you're not running an old version of qemu-kvm in CentOS. Like most
other packages, Red Hat has selected an (old and stable) version as
the baseline version and then backported bugfixes and new features
from newer versions of the package, to fulfill the needs of their
enterprise customers. kvm-83 in CentOS is NOT equal to upstream
kvm-83. That said, as you've probably already read in the docs, KVM is
a technology preview in RHEL 5.x...6.0 will be the first version
with official/stable KVM support by Red Hat.
