Hello Ondra,
Thank you for reporting an issue, its appreciated.
I have to ask something additional, if you had experience with it:
- to work around the current situation, I have added
/etc/cloud/cloud.cfg.d/99_custom-networking.cfg file with following content:
network:
version: 2
ethernets:
eth0:
dhcp4: true
dhcp6: true
eth1:
dhcp4: true
dhcp6: true
- this works, meaning that DHCPV6 address is added, but it results in following
situation: the RA route is killed, rendering VM unreachable
- to solve this one , we added following line, route to link-local ipv6 of the vlan with
runcmd:
runcmd:
- [ ip, "-6", route, add, default, via, "ipv6 : link : local ", dev,
eth0 ]
Still, this yaml is completely ignored/not even parsed. Cloud-init complains (looking at
the logs) of the bad datasource, but I have configured following in the cloud.cfg:
datasource_list: ["NoCloud", "ConfigDrive"]
Thnak you.

Hello,
thanks for the report. This is indeed supported by oVirt, but it's not
supported by ovirt_vm Ansible module, I've opened an issue[1]. Thanks.

Dear oVirt
Would you be so kind to help out clarifying if and how is IPv6 supported
with
-ansible / ovirt_vm / cloud-init boot protocol.
I have created a VM template which by default uses cloud-init with
following:
When I boot the VM from UI, each VM gets IPv4 DHCP and IPv6 DHCP6
address, default cloud-init setup and we have infrastructure for both
IPv4 and IPv6.
However, when calling same template via Ansible ovirt_vm, using following:
cloud_init_nics:
|~
- nic_name:
eth0
|~
nic_boot_protocol:
dhcp
|~
nic_on_boot: true
each VM receives only IPv4 DHCP and only IPv6 RA, but not DHCP IPv6.
Looking at booted VM, following options are not set:
* /etc/sysconfig/network => NETWORKING_IPV6=yes
* Or /etc/sysconfig/network-scripts/ifcfg-eth0 => DHCPV6C=yes and
IPV6INIT=yes
We need IPv6 DHCP6 address , especially for registering it host with DNS
AAAA record.
Is this supported? Am I doing it wrong way?
If its supported please let me know, how can I make sure that VMs
created using Ansible also initialize DHCPV6.
Please assist.
