hi,
i have a two node server 2012 R2 cluster hyper-v which uses 100GB CSV, and 128GB RAM across 2 physical CPU's (approx 7.1GB used when the VM is not booted), and 1 VM running windows 7 which has 64GB RAM assigned, the VHD size is around 21GB and the BIN file is 64GB (by the way do we have to have that, can we get rid of the BIN file?).
NUMA is enabled on both servers, when I attempt to live migrate i get event 1155 in the cluster events, the LM starts and gets into 60 something % but then fails. the event details are "The pending move for the role 'New Virtual Machine' did not complete."
however, when i lower the amount of RAM assigned to the VM to around 56GB (56+7 = 63GB) the LM seems to work, any amount of RAM below this allows LM to succeed, but it seems if the total used RAM from the physical server (including that used for the VMs) is 64GB or above, the LM fails.... coincidence since the server has 64GB per CPU.....
why would this be?
many thanks
Steve
