Check guest network link status of virtio nic with status=on failed (build 110) Steps to Reproduce: 1 boot up guest with following cli (status=on) /usr/libexec/qemu-kvm -name win7-32 -enable-kvm -m 2G -smp 4 -uuid ae361e8d-28a4-4e70-8783-bda0d450ce35 -nodefconfig --nodefaults -chardev socket,id=charmonitor,path=/tmp/win7-32,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -boot order=cd,menu=on -drive file=win.raw,if=none,id=drive-ide0-0-0,format=raw,serial=mike_cao,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive file=driver.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=isa_serial0 -vga qxl -spice disable-ticketing,port=5909 -monitor stdio -qmp tcp:0:4446,server,nowait -netdev tap,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown,id=hostnet1,vhost=off,queues=4, -device virtio-net-pci,netdev=hostnet1,id=net1,mac=1a:46:0b:ca:bc:8c,bus=pci.0,mq=on,vectors=10,status=on 2.Inside guest, ping out from guest 3.Under qemu monitor, set network link down. (qemu)set_link net1 off 4.Inside guest, ping out from guest 5.Reboot guest inside # ctrl+alt+del --> reboot 6.Inside guest, ping out from guest 7.Reboot guest via qemu monitor (qemu) system_reset 8.Inside guest, ping out from guest 9.Under qemu monitor, set network link up. (qemu)set_link net1 on 10.Inside guest, ping out from guest Actual results: After step 3,the network status is still on, can not ping out After step 9,the network status is still off and can not ping out Expected results: After step 3, the network status is off, can not ping out After step 9,the network status is on and can ping out Additional info: 1 All the windows guests hit this issue. 2 build 105 and 7.1.z don't hit this issue, so it is a regression bug. 3 Workaround: After step 9, disable/enable this driver on device manager, the network can ping out. After step 9, reboot the guest, the network status is on and can ping out.
