[Xen-devel] [OSSTEST PATCH 16/22] ts-xen-install: Properly handle hosts without a static IP address

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

From: Robert Ho <robert.hu@xxxxxxxxx>

Check IpStatic, and if it is not set, provide a dhcp stanza in
/etc/network/interfaces, rather than an `inet static' one.

This is necessary for L1 nested hosts, because they don't have a
static IP address.

In principle this makes matters more correct for physical hosts
without static IP addresses, but these are currently not supported
by selecthost().

v14: Only use `inet dhcp' if !$ho->{IpStatic}.
