clean_dhcp_opts(task)[source]

Clean up the DHCP BOOT options for the host in task.

Parameters

get_ip_addresses(task)[source]

Get IP addresses for all ports/portgroups in task.

Parameters

task – a TaskManager instance.

Returns

List of IP addresses associated with task’s ports/portgroups.

supports_ipxe_tag()[source]

Whether the provider will correctly apply the ‘ipxe’ tag.

When iPXE makes a DHCP request, does this provider support adding the tag ipxe or ipxe6 (for IPv6). When the provider returns True, options can be added which filter on these tags.

The dnsmasq provider sets this to True on the assumption that the following is included in the dnsmasq.conf:

dhcp-match=set:ipxe,175

Returns

True
