Hi, I have ovs-dpdk setup and have spawned a VM with 2 vhost-user ports. I am using vhost in dpdkvhostuserclient mode. If I reboot the guest vm by issuing reboot command i am getting SEGV , looked at the stack trace , (my guess it might be accessing old Queue memory).
is there a compatibility matrix for "vhost_net" driver used in the guest and ovs-dpdk version. dpdk-17.11-7 openvswitch-2.9.0 #0 0x00005625f482f34c in rte_vhost_dequeue_burst () <--- Its trying to access VM memory ,on reboot #1 0x00005625f49762e4 in netdev_dpdk_vhost_rxq_recv () #2 0x00005625f48c2671 in netdev_rxq_recv () #3 0x00005625f489bc1f in dp_netdev_process_rxq_port () #4 0x00005625f489c02a in pmd_thread_main () #5 0x00005625f4918cb6 in ovsthread_wrapper () #6 0x00007f817384bdc5 in start_thread () from /lib64/libpthread.so.0 #7 0x00007f8172c4e73d in clone () from /lib64/libc.so.6 -- Thanks and Regards, Pradeep.K.S.
