Hi All I just encounter a problem, the xen vm network suddenly does not work even though no one change the configuration. and I restart the network service, it still does not work. After rebooting the VM, network works well. and I find the xen host have below log in /var/log/messages: Oct 23 20:22:08 app_xen5 kernel: xenbr0: port 5(vif6.0) entering disabled state Oct 23 20:22:08 app_xen5 kernel: device vif6.0 left promiscuous mode Oct 23 20:22:08 app_xen5 kernel: xenbr0: port 5(vif6.0) entering disabled state Oct 23 20:22:34 app_xen5 kernel: device vif9.0 entered promiscuous mode Oct 23 20:22:34 app_xen5 kernel: ADDRCONF(NETDEV_UP): vif9.0: link is not ready Oct 23 20:22:38 app_xen5 kernel: blkback: ring-ref 8, event-channel 27, protocol 1 (x86_32-abi) Oct 23 20:22:41 app_xen5 kernel: ADDRCONF(NETDEV_CHANGE): vif9.0: link becomes ready Oct 23 20:22:41 app_xen5 kernel: xenbr0: topology change detected, propagating Oct 23 20:22:41 app_xen5 kernel: xenbr0: port 5(vif9.0) entering forwarding state Xen version is as below: host : app_xen5 release : 2.6.18-128.el5xen version : #1 SMP Wed Dec 17 12:22:24 EST 2008 machine : i686 nr_cpus : 16 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 4 threads_per_core : 2 cpu_mhz : 2400 hw_caps : bfebfbff:28100000:00000000:00000140:009ce3bd:00000000:00000001 total_memory : 12279 free_memory : 0 node_to_cpu : node0:0-15 xen_major : 3 xen_minor : 1 xen_extra : .2-128.el5 xen_caps : xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p xen_pagesize : 4096 platform_params : virt_start=0xf5800000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 20080704 (Red Hat 4.1.2-44) cc_compile_by : mockbuild cc_compile_domain : redhat.com cc_compile_date : Wed Dec 17 11:38:33 EST 2008 xend_config_format : 2 Could anyone tell me the reason why the vm network suddenly could not work? thanks in advance.
