This is for the guest vms to access > user-data and ssh-keys from the Router VM. > Please refer to bug https://issues.apache.org/jira/browse/CLOUDSTACK-2644 for > more info. > Making this entry in the hosts file is part of cloud-early-config file and > every time a router is rebooted new entry would be made to the hosts file. > If the router reboots multiple times for some reason, we see lot of duplicate > entries in the hosts file. > Following is the contents from /etc/hosts file from VR which was rebooted for > multiple times: > 127.0.0.1 localhost > # The following lines are desirable for IPv6 capable hosts > ::1 localhost ip6-localhost ip6-loopback > ff02::1 ip6-allnodes > ff02::2 ip6-allrouters > 10.147.43.6 data-server > 10.147.43.6 r-4-VM > 10.147.43.6 data-server > 10.147.43.6 r-4-VM > 10.147.43.6 data-server > 10.147.43.6 r-4-VM > 10.147.43.5 s1 > 10.147.43.7 s1-passwd > 10.147.43.10 addaf9b0-bdbc-4c4a-80ed-67664ad781e0 > 10.147.43.8 3b2804dd-225d-4cf3-bcdc-fed468c61192 > 10.147.43.130 s2 > 10.147.43.132 0e0df8e6-2c0f-455b-8571-b5f6a0dbd44e > 10.147.43.133 s2-passwd > 10.147.43.134 bf2e0e55-a2c9-4d26-a489-b8d8aa596350 > It would be good to check for the entries present in the file before > appending to it and avoid duplicate entries. -- This message was sent by Atlassian JIRA (v6.1#6144)
