Xen compute is CentOS 6.5, KVM compute node is RHEL 6.5. On the XEN node, I see:

 tm1cldcmpl03 QEMU  32  0   920MB   512MB   2.0GB   0Bytes  0<BR>

On the KVM node I see:

 tm1cldcmpl02 QEMU  32  5   31GB    3GB 2.0GB   55.0GB  5

These are identical HP Proliant DL380 gen8 system with 32 cores and 32gb of memory. I can't launch anything on xen system because it doesn't think it has enough memory to do anything.

Here's not nova compute log excerpt:

And why would the # of vcpus in use be different?
