Patch proposed upstream: https://www.redhat.com/archives/libvir-list/2012-March/msg00051.html packages:
libvirt-0.9.10-5.el6.x86_64
qemu-kvm-0.12.1.2-2.247.el6.x86_64
kernel-2.6.32-244.el6.x86_64
follow the steps in description:
# virsh attach-interface libvirt_test_api network default vnet2 --persistent
Interface attached successfully
# virsh dumpxml libvirt_test_api|grep -3 vnet2
<interface type='network'>
<mac address='52:54:00:4a:c1:ee'/>
<source network='default'/>
<target dev='vnet2'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</interface>
# virsh detach-interface libvirt_test_api network --mac 52:54:00:4a:c1:ee --persistent
Interface detached successfully
so this is fixed.

Description of problem: the guest's mac will change after attach a vnet with the option persistent and then restart it. Version-Release number of selected component (if applicable): libvirt-0.9.8-1.el6.x86_64 qemu-kvm-0.12.1.2-2.209.el6.x86_64 kernel-2.6.32-220.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. Attach a vnet with the options --persistent a healthy guest named rhel6. # virsh attach-interface rhel6 network default vnet1 --persistent # virsh dumpxml rhel6 | grep -3 vnet1 <interface type='network'> <mac address='52:54:00:B5:58:B0'/> <source network='default'/> <target dev='vnet1'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> 2.Dettach the vnet. #virsh detach-interface rhel6 network --mac 52:54:00:b5:58:b0 --persistent error: Failed to detach interface error: invalid argument: no nic of mac 52:54:00:B5:58:B0 3.Restart the guest and check the mac # virsh destroy rhel6 Domain rhel6 destroyed # virsh dumpxml rhel6 /*you will find this*/ <interface type='network'> <mac address='52:54:00:f8:5e:7a'/> <source network='default'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> #virsh start rhel6 Domain rhel6 started # virsh dumpxml rhel6 | grep -3 vnet1 <interface type='network'> <mac address='52:54:00:f8:5e:7a'/> <source network='default'/> <target dev='vnet1'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Actual results: the mac change from 52:54:00:B5:58:B0 to 52:54:00:f8:5e:7a Expected results: the mac should not change Additional info: If no the --persistent , it work well
