Bug Description

On the eucalyptus NC, the VM-Dir cache size is not recognized. In my eucalyptus.conf (on the NC) i have:

...
# This directory should be local to the Node Controller (as
# opposed to a NFS share) for performance reasons.
INSTANCE_PATH="/var/lib/eucalyptus/instances"

# The maximum amount of disk space, in Megabytes, that Eucalyptus is
# allowed to use in the cache directory (INSTANCES_PATH/eucalyptus/cache).
# A generous size is recommended. Setting this to zero disables caching.
NC_CACHE_SIZE="50000"
....

Once i restart the eucalyptus service via

service eucalyptus-nc restart

I get in the /var/log/eucalyptus/nc.log

Have you checked if the maximum size is actually enforced or you're basing your report on the log message:
