[tck PATCH 2/9] Use $net->get_dhcp_leases() when available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Newer versions of libvirt no longer let dnsmasq create a leases file,
they keep track of it themselves and provide an API to retrieve the
current list of leases. Use that to get the guest's IP address when
it's available.
---

I later realized that it might be more appropriate to use
$dom->get_interface_addresses(), but I'd already rewritten the
existing function this way and it works, so I left it.
