I see a minor bug here: I think that "vlan": "all" probably should not list the vlan table. NHot sure it's worth fixing for 7.2. The reason you see vlan all is probably because you queries the table before guest booted completely. Pls wait for guest to boot, then you should see the vlan table in normal state. oh I didn't notice it's with vhost-user. that one doesn't support ctrl_vlan so it's expected that all vlans are allowed. Again, listing them all is a minor bug. (In reply to Michael S. Tsirkin from comment #3) > oh I didn't notice it's with vhost-user. > that one doesn't support ctrl_vlan so it's expected that all vlans > are allowed. > Again, listing them all is a minor bug. Hi, Michael Yes, it only occurs with vhost-user, so should I change the bug to RFE? Thanks, Qian |
Description of problem: When set ctrl_vlan=on, the "query-rx-filter" still can flush the vlan table. Version-Release number of selected component (if applicable): qemu-kvm-rhev-2.3.0-23.el7.x86_64 guest&host kernel-3.10.0-316.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Boot guest with vhost-user, and set ctrl_vlan enabled: # /usr/libexec/qemu-kvm -name rhel71-br0-1 -S -machine pc-i440fx-rhel7.2.0,accel=kvm,usb=off -cpu IvyBridge -m 4096 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 -object memory-backend-file,prealloc=yes,mem-path=/dev/hugepages/qemu,share=on,size=4096M,id=ram-node0 -numa node,nodeid=0,cpus=0-3,memdev=ram-node0 -uuid 7907dc99-aa2d-4a3e-9fca-6087f3cfbbe6 -no-user-config -nodefaults -rtc base=utc,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -boot menu=on -drive file=/home/rhel72cp1.qcow2,if=none,id=drive-virtio-disk0,format=qcow2 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -chardev socket,id=charnet0,path=/var/run/openvswitch/vhost-user1 -netdev type=vhost-user,id=hostnet0,chardev=charnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:01:0b:11,bus=pci.0,addr=0x9,ctrl_vlan=on -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -spice port=5901,disable-ticketing,seamless-migration=on -device qxl,id=video0,ram_size=67108864,vram_size=67108864,vgamem_mb=16,bus=pci.0,addr=0xe -msg timestamp=on -monitor stdio -qmp unix:/tmp/q1,server,nowait 2. Try to do the "query-rx-filter" { "execute": "query-rx-filter", "arguments": { "name": "net0" } } 3. Actual results: The ctrl_vlan does not work: ** since the vlan table is huge, I use "..." to replace the vlan numbers. { "execute": "query-rx-filter", "arguments": { "name": "net0" } } {"return": [{"promiscuous": false, "name": "net0", "main-mac": "52:54:00:01:0b:11", "unicast": "normal", "vlan": "all", "vlan-table": [4095, 4094, 4093, 4092, 4091, 4090, ..., 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0], "unicast-table": [], "multicast": "normal", "multicast-overflow": false, "unicast-overflow": false, "multicast-table": ["33:33:ff:01:0b:11", "33:33:00:00:00:01", "01:00:5e:00:00:fb", "01:00:5e:00:00:01"], "broadcast-allowed": false}]} Expected results: If ctrl_vlan enabled, the vlan table should be empty. Additional info: 1.This bug is not regression, I tried with qemu-kvm-rhev-2.1.2-23.el7.x86_64(7.1GA), can hit such issue too. 2.With tun/tap, works well.
