Hi Yuko, NUMA is splitting memory+cpu into smaller cells, where each cell has cpu+ram. This is possible in real machines, and also inside the guest. The best performance is achieved when you make sure each virtual cell (virtual node / vnode) is pinned to a physical cell (pnode). If the physical node is smaller than the vnode, or occupied with other VMs, you will get this error. Doron

Hi Doron, Thank you very much for your explanation. I think I understand the concept now but I would like to double check with you -- can it be re-phrased as: "cannot allocate memory to the VM's virtual NUMA nodes which is pinned to host's physical NUMA nodes." (I also want to check accommodate vs allocate) Kind regards, Yuko

Hi Yuko, this is about node (cell) capacity, so we should try and keep it simple.
Kind regards,
Yuko

Hi Doron, Thank you very much for your reply again. It makes sense now. Many thanks for your help. Yuko
