Hi,

is it possible to allow more Instances per Node Controller than existing?

At the moment I have 12 real Cores in my Eucalyptus Cloud and the maximum of Instances is 12.

Is it possible to allow 8 Instances per Node Controller with MAX_CORES="8" in /opt/eucalyptus/etc/eucalyptus/eucalyptus.conf ?

Regards,
Christian

Yes, MAX_CORES works both ways a value smaller than the actual number of cores will prevent Eucalyptus from using all of your cores, while a larger value will enable multiplexing of VMs.
