Hi All,
I am trying vhost-user configuration on Cavium's aarch64 SoC using VPP v1704. I mainly followed steps provided at following https://wiki.fd.io/view/VPP/Use_VPP_to_connect_VMs_Using_Vhost-User_Interface I am able to launch two VM's using qemu-system-aarch64. The host and guest kernel version is 4.12.9. I am also able to configure two virtual interface described in above documentation link. However as soon as I provide IP address to first VM interface using ifconfig or ip addr add command, the vpp process on host crashes. I was watching "vppctl show_interface" where I saw one packet received by vpp at Virtual1 interface and after then I think vpp process crashed so vppctl got hang. I have attached gdb crash dump "gdb_crash_log.txt". I have also attached command I used to launch VM1 and VM2: vm1_launch.sh, vm2_launch.sh. Any pointers will be really helpful. Thanks, Nitin
