Re: [libvirt-users] is memoryBacking support 'share' and 'mem-path' parameter

Hi, I want to use this qemu command '-object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on' with libvirt but i can't find the 'mem-path' and 'share' in the documentation. because the vhost-user backend based on 'share=on' parameter and libvirt support vhostuser i guess there maybe another way to support this parameter? this is my xml: <cpu> <numa> <cell id='0' cpus='0' memory='1048576' memAccess='shared'/> <cell id='1' cpus='1' memory='1048576' memAccess='shared'/>

</numa> </cpu> <memoryBacking> <hugepages> <page size="2" unit="M" nodeset="0,1"/> </hugepages> <!--nosharepages/--> <!--locked/--> </memoryBacking> <interface type='vhostuser'> <mac address='52:54:00:3b:83:1a'/> <source type='unix' path='/path/port1' mode='client'/> <model type='virtio'/> </interface> <interface type='vhostuser'> <mac address='52:54:00:3b:83:1b'/> <source type='unix' path='/path/port2' mode='client'/> <model type='virtio'/> </interface> when i create the VM the qemu command is like this without 'share=on' parameter: -object memory-backend-file,prealloc=yes,mem-path=/dev/hugepages/libvirt/qemu,size=1024M,id=ram-node0 -numa node,nodeid=0,cpus=0,memdev=ram-node0 -object memory-backend-file,prealloc=yes,mem-path=/dev/hugepages/libvirt/qemu,size=1024M,id=ram-node1 -numa node,nodeid=1,cpus=1,memdev=ram-node1 _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
