How Can I Move A VM From 1 Network Def To Another

etpoole60 · 11-02-2014, 08:07 PM

If you look in the Network Forum you will see several posts concerning the loss of network connectivity to a VM after a power loss.

I've narrowed it down to the BR0 definition on the host system. I've defined a new bridge, BR1, and built a new VM that works perfectly.

That brings about my question on this Forum:

How do I move a VM from 1 bridge network to another?

My host system is running CentOS 5.11 x86_64, AMD 6-Core CPU, 32 GB RAM, 4 Physical NICs, 6 disk drives in RAID-1 definitions, KVM virtualization.

TIA,
Gene

Modify the xml file of the KVM vm.

An alternative method is to rename the old bridge in /etc/udev* and /etc/sysconfig/network*. Name your new working bridge br0. Restart networking. Restart VM.
