From 832bc1f47fce1b61f23259502c08f9253656cb38 Mon Sep 17 00:00:00 2001 From: Jaroslav Henner Date: Wed, 30 Sep 2015 20:51:35 +0200 Subject: Prevent dns resolution recursion (loop). The dnsmasq should not be resolving the example.com recursively, because in case that we have /etc/NetworkManager/dnsmasq.d/libvirt_dnsmasq.conf: server=/example.com/192.168.55.1 the dnsmasq will be asking itself, therefore a dns resolution loop is created, which causes Maximum number of concurrent DNS queries reached (max: 150) and performance degradation of dns resolution on the whole hypervizor and guests. This patch will fix that in the domain.xml, which will cause adding local=/example.com/ to the /var/lib/libvirt/dnsmasq/openshift-ansible.conf, effectively fixing the problem. --- playbooks/libvirt/openshift-cluster/templates/network.xml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'playbooks/libvirt') diff --git a/playbooks/libvirt/openshift-cluster/templates/network.xml b/playbooks/libvirt/openshift-cluster/templates/network.xml index 86dcd62bb..050bc7ab9 100644 --- a/playbooks/libvirt/openshift-cluster/templates/network.xml +++ b/playbooks/libvirt/openshift-cluster/templates/network.xml @@ -8,7 +8,7 @@ - + -- cgit v1.2.3
