Cloned kvm virtual machine's mac address starts with '00:16:3e' like Xen.
Last modified: 2013-08-04 23:43:38 EDT
Version-Release number of selected component (if applicable): python-virtinst-0.600-7.el6.noarch How reproducible: 100% Steps to Reproduce: 1. Make sure there is a kvm guest with NIC, its mac address should be start with '52:54:00'. 2. Clone the guest using "virt-clone -o demo -n newdemo --mac=RANDOM -f /var/lib/libvirt/images/newdemo.img --debug" 3. Waiting for clone task finished. 4. Check the cloned guest's mac address Actual results: 1. Cloned guest's mac address starts with '00:16:3e' like Xen. Expected results: 1. Cloned guest's mac address starts with '52:54:00'. Additional info: 1. Don't do this through virt-manager, if you do that, everything will be OK. 2. Since there is nothing in libvirtd.log, so I didn't attach it.
Created attachment 566783 [details] This is what I got from terminal with --debug option
Hi Cole, The python-virtinst only judges 'xen' and 'qemu' domain type, and 'xen' is a default domain type. If a guest is 'kvm' domain type, python-virtinst thinks it's invalid/KeyError then set default 'xen' type: # virtinst/util.py: def randomMAC(type="xen"): <snip> ouis = { 'xen': [ 0x00, 0x16, 0x3E ], 'qemu': [ 0x52, 0x54, 0x00 ] } try: oui = ouis[type] except KeyError: oui = ouis['xen'] </snip> Regards, Alex

Fixed in python-virtinst-0.600.0-8.el6
Verified pass with the packages: python-virtinst-0.600.0-8.el6 virt-manager-0.9.0-11.el6 Test steps: Same as the description. Test results: 1. The cloned kvm domain now has mac address starts with '52:54:00'. And change this bug to VERIFIED
