-Global configuration is stored in '/etc/vzdump.conf'.
+Global configuration is stored in '/etc/vzdump.conf'. The file uses a
+simple colon separated key/value format. Each line has the following
+format:
 
- tmpdir: DIR
+ OPTION: value
- dumpdir: DIR
+
- storage: STORAGE_ID
+Blank lines in the file are ignored, and lines starting with a '#'
- mode: snapshot|suspend|stop
+character are treated as comments and are also ignored.
- bwlimit: KBPS
+
- ionize: PRI
+We currently support the following options:
- lockwait: MINUTES
+
- stopwait: MINUTES
