[Bug 1831652] [NEW] fixing the case where we use every single page in 1 vm
Public bug reported:
Got this error: qemu-kvm: -object memory-backend-ram,id=ram-
node0,size=12884901888,host-nodes=0,policy=bind: cannot set up guest
memory 'ram-node0': Cannot allocate memory.
My Hardware: 32CPU / 32G memory
Flavor: 30 vCPU / 24000 MB (24G) memory
Grub hugemem setting: hugepagesz=2M hugepages=12288
[root@ostack-compute-sriov-196 ~]# cat /sys/devices/system/node/node*/meminfo | grep -i hugepage
Node 0 AnonHugePages: 0 kB
Node 0 HugePages_Total: 6144
Node 0 HugePages_Free: 394
Node 0 HugePages_Surp: 0
Node 1 AnonHugePages: 0 kB
Node 1 HugePages_Total: 6144
Node 1 HugePages_Free: 394
Node 1 HugePages_Surp: 0
Solution was set 23000 MB (23G) in flavor to make it work.

vm.
