Comment 8 for bug 1298921

Thiago,
  the CloudSigma datasource is the one that is doing the http requests listed above. That datasource cannot be configured with timeout. It should be a fairly easy fix to add that.

Note, though that if you're hitting the cloudsigma datasource, you are likely running on cloudsigma or there is another bug.

the cloudsigma code in trunk at the moment does a 'is_running_cloudsigma' check that should have very few false positives. See:
  http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/cloudinit/sources/DataSourceCloudSigma.py#L45

it should only return True if 'system-product-name' from the host-provided dmi data has 'cloudsigma' in it.
