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.
