Hello,
I using the latest Liberty and I am trying to bring up a VM with some numa
options configured using flavor. Specifically I need to give this VM 16GB of
RAM and in addition it will need to use 12x1GB huge pages. What I found out,
there is no way in a flavor to specify RAM size and separately number of huge
pages, only size is avaialbe, so to achieve what I needed I had to specify
RAM size of 30GB. It would not be that bad, but instead of taken 16GB from
server's RAM and 12 GB from Huge pages it has taken whole 30GB out of the
server's total huge pages pool. Huge waist!!!
Anybody hit similar requirement and found a reasonable solution? Greatly
appreciate any feedback.
As far as I know there is no generic way to specify a VM with a mix of regular
and huge pages.
Can you do this with your bare hypervisor?
Chris
