I am using red-hat 7.4 and ovs 2.6.1 with dpdk 16.11 In my setup I am using qemu-kvm without openstack. I am trying to use ovs with dpdk. In my xml file I added following lines for the dpdkvhostuser <cpu mode='host-passthrough'> <numa> <cell id="0" cpus="0-6" memory="16777216" unit='KiB' memAccess="shared"/> </numa> </cpu>
I have enabled hugepages during boot time ot@mvmgptb11hyp01 hyp-1]# cat /proc/meminfo | grep -i hugeAnonHugePages: 126976 kBHugePages_Total: 100HugePages_Free: 80HugePages_Rsvd: 0HugePages_Surp: 0Hugepagesize: 1048576 kB But When I start my vm (virsh start vm1.xml) I am seeing that this vm is not using memory from hugepages, rather it is taking memory from total memory. When I checked the log file I see that it is usingmem-path=/var/lib/libvirt/qemu/ram,share=yes It should use backend memory as following mem-path=/dev/hugepages/libvirt/qemu/vm1,share=yes Any idea how can I use memory from hugepages~
