Hi all,
I have another question on a 3.6 string.
*File:***AppErrors
*Resource ID:***VAR__DETAIL__NOT_MEMORY_PINNED_NUMA
*String:***$detailMessage cannot accommodate memory of VM's pinned
virtual NUMA nodes within host's physical NUMA nodes.
*Question:* I have a bit of difficulty clearly understanding this
string. Particularly the part "memory of VM's pinned virtual NUMA nodes"
Could anyone paraphrase this? (Could it possibly be "memory of VM's
pinned to virtual NUMA noteds"?)
Thank you,
Yuko
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.
