Summary: New VM instantiations trigger 2 second DNS outage Key: CLOUDSTACK-2299 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2299 Project: CloudStack Issue Type: Bug Security Level: Public (Anyone can view this level - this is the default.) Components: Network Controller, Network Devices Affects Versions: 4.0.1, 4.0.0, pre-4.0.0 Environment: Virtual Router used for DHCP, DNS services Reporter: Dennis Lawler Every time a new VM is started up, there is a 2 second outage in DNS services that can cause problems in guest VMs that use the router VM for DNS. For Cloudstack configurations using both DHCP and DNS services on the router VM (both implemented with dnsmasq), there is currently a 2 second DNS service outage every time a new VM is instantiated The source of this outage is in edithosts.sh, which uses “service dnsmasq restart” to pick up the freshly added DNS and DHCP entries. Restarting the dnsmasq service triggers a sleep for 2 seconds after killing dnsmasq before starting it back up again.
