ipv6 address are not injected unless 1 fixed_ip exists, also it will be injected multiple times if there are more than 1

[Trey Morris]

this bug is in the _get_network_info in virt/xenapi/vmops.py function. It probably exists in the libvirt equivalent as well.

Can you please explain how can I reproduce this problem? Can you attach any logs?
How can I assign multiple fixed ip address to an instance?

Thanks.

I noticed the issue in code. I didn't need to test for it, so there are no logs. You can reproduce the issue by assigning multiple fixed IPs, and also using ipv6. Currently multiple fixed_ips has to be done by direct manipulation of the fixed_ips table. Once you have created multiple fixed IPs, use the console to make a call to xenapi/vmops._get_network_info(). You'll see that the "ip6s" field in the returned dict will contain the ip6 address repeated multiple times. You can also perform the test by enabling ipv6, and assigning no fixed_ips (again requires direct manipulation of the table, though i guess this could be done through a console as well). When no fixed_ips exist for an instance, there will be no "ip6s" in the dict returned by _get_network_info() even if you had expected there to be.

I also just realized that inject_network_info() and reset_netowrk() can't be called from the os_api (or compute) because the parameters changed in xs_multi_nic. I fixed these issues.

Thank you very much for the detailed explanation. Now I am very clear about it.
