I think you also will need to add following in <qemu:commandline> section. <qemu:arg value='-object'/> <qemu:arg value='memory-backend-file,id=mem,size=8G,mem-path=/dev/shm,share=on'/> <qemu:arg value='-numa'/> <qemu:arg value='node,memdev=mem'/> Thanks Vivek _______________________________________________ Virtio-fs mailing list [email protected] https://www.redhat.com/mailman/listinfo/virtio-fs
