Description Mike Burns 2011-12-16 19:31:47 UTC

+++ This bug was initially created as a clone of Bug #768488 +++

Description of problem:

most of the commands executed by RHEV-M on rhev-h is done by vdsmd using privileges of "vdsm" user and sudo will be used if root privileges are required. Sudo does hostname to IP resolution before executing the command. If the hostname is not resolvable and one of the DNS servers in /etc/resolv.conf is down (not pingable), then sudo will take 30 seconds to finish 6 tries with 5 second timeout. Since an action scheduled from rhev-m (like active a vds) requires a lot of commands run via sudo and since each command takes 30 seconds, the action may timeout.

To prevent this, it may be beneficial to add hostname -> Ip mapping in /etc/hosts.
