could you elaborate more on what src command line migrating to what dst command
line?
The src cmdline:
$QEMU -enable-kvm -cpu host -smp 4 /path/to/img \
-m 2G \
-netdev tap,id=mynet1,vhost=on \
-device virtio-net-pci,netdev=mynet1,mac=52:54:00:12:34:58 ...
The dst cmdline:
$QEMU -enable-kvm -cpu host -smp 4 /path/to/img \
-m 2G -numa node,memdev=pc.ram -mem-prealloc \
-object
memory-backend-file,id=pc.ram,size=2G,mem-path=/dev/hugepages,share=on \
-chardev socket,id=char0,path=/tmp/sock0 \
-netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,netdev=mynet1,mac=52:54:00:12:34:58 \
-incoming tcp:0:4444 ...
Thanks,
