Does it works with e1000? (In reply to comment #1) > Does it works with e1000? vlan_tag works well using e1000. Only rtl8139 exists this problem. This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release. |
Description of problem: When run vlan test in the guests, After configure by vconfig command, 802.1q vlan on guest with rtl8139 nic doesn't effect. Vlan test the 802.1q vlan function of nic(rtl8139/e1000/virtio) on guest, testing steps: 1) Create two VMs with rtl8139/e1000/virtio nic 2) Setup guests in different vlan by vconfig and test communication by ping using hard-coded ip address 3) Setup guests in same vlan and test communication by ping 4) Recover the vlan config Version-Release number of selected component (if applicable): etherboot-zroms-kvm-5.4.4-10.el5 kmod-kvm-83-105.el5 kvm-83-105.el5 kvm-tools-83-105.el5 kvm-qemu-img.83-105.el5 kvm-debuginfo-83-105.el5 How reproducible: 100% Steps to Reproduce: 1.Boot two VMs with rtl8139 nic on host 2.Setup guests in different vlan by vconfig and test communication by ping using hard-coded ip address On guest1: #vconfig add eth0 10 #ifconfig eth0.10 192.168.123.11 On guest2: #vconfig add eth0 20 #ifconfig eth0.20 192.168.123.12 #ping 192.168.123.11 3.Setup guests in same vlan and test communication by ping On guest1: #vconfig add eth0 10 #ifconfig eth0.10 192.168.123.11 On guest2: #vconfig add eth0 10 #ifconfig eth0.10 192.168.123.12 #ping 192.168.123.11 Actual results: Guest is unexpectedly pingable in different vlan Expected results: 1. guests in different vlan can't ping successfully 2. guests in same valn can ping successfully Additional info: 1. qemu-kvm command line: /home/amos/Project/multi/kvm-autotest/client/tests/kvm_runtest_2/qemu -name 'vm1' -monitor tcp:0:5400,server,nowait -drive file=/home/amos/Project/multi/kvm-autotest/client/tests/kvm_runtest_2/images/RHEL-Server-5.3-64.0.qcow2,if=ide,boot=on -net nic,vlan=0,macaddr=00:11:22:33:8D:01,model=rtl8139 -net tap,vlan=0,ifname=rtl8139,script=/etc/qemu-ifup-switch,downscript=no -m 512 -usbdevice tablet -rtc-td-hack -no-hpet -cpu qemu64,+sse2 -smp 1 -vnc :0 /home/amos/Project/multi/kvm-autotest/client/tests/kvm_runtest_2/qemu -name 'vm2' -monitor tcp:0:5401,server,nowait -drive file=/home/amos/Project/multi/kvm-autotest/client/tests/kvm_runtest_2/images/RHEL-Server-5.3-64.0.qcow2,if=ide,boot=on -net nic,vlan=0,macaddr=00:11:22:33:8D:02,model=rtl8139 -net tap,vlan=0,ifname=tap_rtl8139_2,script=/etc/qemu-ifup-switch,downscript=no -m 512 -usbdevice tablet -rtc-td-hack -no-hpet -cpu qemu64,+sse2 -smp 1 -vnc :1 2.cpuinfo: Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz 3.network status [root@dhcp-66-70-53 staf-kvm]# brctl show bridge name bridge id STP enabled interfaces switch 8000.0023ae8ff38d no tap_rtl8139 tap_rtl8139_2 eth0 virbr0 8000.000000000000 yes
