virt-manager does not work properly with bridge devices on top of bonding devices

Issue

When a bonding device (bond0) was configured from eth0 and eth2 on the KVM host and tried to create a bridge (br0)
from bond0 in virt-manager(*1), the configuration files of the slave interfaces of bond0 (ie, ifcfg-eth0 and ifcfg-eth2)
were deleted unexpectedly and bond0 stopped working after the host was rebooted.

(*1) Open the "Connection Details" window and create the bridge device from the "Network Interfaces" tab.
