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.

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