Re: [virt-tools-list] IPv6 and DHCPv6 support

Virt-manager lacks support for DHCPv6 and some other aspects of IPv6. If you want the following entered into bugzilla, I will do so but I thought that something to the list first might help.

DHCPv6 support is in the process of being added to libvirt. The update is pretty much complete and lack some additional testing I want to do and plus updating the documentation so that folks will know how to use it.

1. There is a lack of communication between what virsh net-* does and virt-manager. If virsh makes changes, the old values remain with virt-manager.

2. If virsh is used to add a IPv6 dhcp-range to a network definition, virt-manager appears to get completely confused about that device ... it should at least tolerate it!

3.  I should be able to specify an IPv6 (gateway) address with VM.

4. I should be able to create a virtual network with either IPv6 or IPv4 or both defined.

5. I should be able to specify a dhcp-range for an IPv6 subnet.

If VM was written in C I might be able to be more direct help. But, it is written in python and my learning curve to get proficient enough would be on the long-side.

Is there any chance at least some of this will be addressed sooner rather than later?

I was wrong about one thing: VM can and does tolerate IPv6 dhcp-range and IPv6 dhcp-host specifications.

However, there was also a bug found ... it is valid to specify prefix= rather than netmask= for an IPv4 address definition but virt-manager cannot handle this.
