| Doc Text: |
The /etc/resolv.conf file was being overwritten every time a change was made to networking. The statement PEERDNS="no" is now added to all interface configuration (ifcfg*) files created by the hypervisor. This prevents the incorrect overwriting of the resolv.conf file.

Test only, no code change Correct the verify steps as below, on build rhev-hypervisor-5.7-20120103.1: 1. on multi-nics machine, setup one nice and dns during install 2. after reboot, all other nics have "PEERDNS=no" in ifcfg-ethX. 3. add "BOOTPROTO=dhcp" in ifcfg-ethX and ifup them, /etc/resolv.conf is not changed. the bug is verified.

New Contents:
When the hypervisor was installed on a machine with multiple Network Interface Cards (NICs), and only one NIC wass configured at install time, the resolv.conf file would be overwritten each time a change was made to networking. The statement PEERDNS="no" is now added to all interface configuration (ifcfg*) files created by the hypervisor. This prevents the incorrect overwriting of the resolv.conf file.
