Example (a) create your disk image file with qemu-img (b) create a bridge (br0) (c) create a tap interface (tap0) (d) bind eth0 and tap0 to br0 (e) start up kvm from command line like shown below (it is for openSUSE, the utility name could be different in CentOS) qemu-kvm -enable-kvm -daemonize -vga std \ -m 256 \ -hda $KVM_DIR/vdisks/debian.vdd \ -net nic,model=rtl8139,macaddr=${nic_mac_addr0} \ -net tap,ifname=tap0,script=no,downscript=no #-boot d \ #-cdrom /media/Transcend1TB/ISO/debian/debian-testing-amd64-DVD-1.iso where KVM_DIR is $HOME/KVM and ${nic_mac_addr0} is an unique MAC address. The last two lines have been commented out after installing Debian, to install OS from ISO uncomment the lines. Some of the options may vary on CentOS - I have not delved with KVM on CentOS as host.
