Open Stack

Hello all,

I've been working at getting an ironic setup going (following the 
installation guide 
http://docs.openstack.org/developer/ironic/deploy/install-guide.html).

I'm up to the node creation step and have some questions

1) In regards to the baremetal flavor, how closely do the extra-specs 
need to match the physical node?
         a) The node I'm working with has a strange amount of memory, 
65952964 KiB which does not evenly map to the MiB units requested by 
ironic (65952964 KiB / 1024 = 64407.1914063 MiB). What kind of rounding 
should I do?
         b) Should the 'local_gb' property of the node be the size (in 
GiB) of the partition where the os will be installed or should it be the 
sum of the partitions?

2) Does pxe_root_gb refer to the size of the partition where the OS will 
be installed or is it something else?

I appreciate any insight, thanks for the help!
