<pre wrap="">Hi all,
I have another question on a 3.6 string.
*<a class="moz-txt-link-freetext" href="File:***AppErrors">File:***AppErrors</a>
*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

<pre wrap="">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.

<pre wrap="">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)

Hi Yuko,
this is about node (cell) capacity, so we should try and keep it simple.</pre>

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