To qemu-discuss,
This is my first subscribing to this mail list. My name is Caleb Yu. I am a graduate student studying time synchronization protocols. My setup is as followed. A POX SDN controller connected to an Openvswitch running openflow 1.0. The openvswitch is connected to two QEMU VMs. VM1 is PTP master and VM2 is PTP slave.
My command for setting up QEMU is:
sudo qemu-system-x86_64 -m 1028 -net
nic,macaddr=00:00:00:00:cc:10 -net
tap,script=/etc/ovs-ifup,downscript=//etc/ovs-ifdown -drive
file=/home/pads/Desktop/kvmguest/pads1.qcow2 -vnc :1
sudo qemu-system-x86_64 -m 1028 -net
nic,macaddr=00:11:22:cc:cc:10 -net
tap,script=/etc/ovs-ifup,downscript=//etc/ovs-ifdown -drive
file=/home/pads/Desktop/kvmguest/pads3.qcow2 -vnc :2
The observation is that the synchronization time is longer than normal for such a network. Is there some configuration I am missing in order for VM2 to synchronize VM1 without delay? Or do I have to use newer QEMU inorder to run time synchronization tests properly? Thank you.
Sincerely,
Caleb Yu
