Description of problem:
I'm installing a fully virtualized Xen guest using the latest RHEL6 snapshot. By default virt-manager will assign only one NIC to the guest but anaconda reports two. Running ifconfig on tty2 during install shows that there are 2 NICs which have the same HWADDR. This could be related to bug #621846.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. On a RHEL5.5 Xen host start install of a new domU
2. Select fully virtualized, type/variant: Linux/RHEL6, boot from boot.iso
During stage1 of anaconda there's a screen to configure TCP/IP which shows 2 NICs. In stage2 ifconfig also shows two NICs with the same hadware address.
Only one NIC because only one interface is assigned to the guest.
