+#### I have repository access errors during VM provisioning!
+
+Sometimes VM provisioning may fail with errors that look like this:
+
+```
+Timeout was reached for https://mirrors.fedoraproject.org/metalink?repo=fedora-23&arch=x86_64 [Connection timed out after 120002 milliseconds]
+```

+You may use a custom Fedora repository URL to fix this:

+```shell
+export CUSTOM_FEDORA_REPOSITORY_URL=https://download.fedoraproject.org/pub/fedora/
