Created attachment 933228 [details] communication ports after hotplug Description of problem: communication ports were marked with a yellow exclamation after hotplug pci-serial,pci-serial-2x,pci-serial-4x Version-Release number of selected component (if applicable): virtio-win-prewhql-90 qemu upstream v2.1.0-rc5 & qemu-kvm-1.5.3-69.el7.x86_64 kernel-3.10.0-123.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.boot win2012 guest with: qemu-system-x86_64 -cpu Nehalem -enable-kvm -m 2048 -smp 4,sockets=2,cores=2,threads=1 -name test -rtc base=utc ile=win2012.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,werror=stop,rerror=stop,aio=native -device ide-drive,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,id=hostnet0,vhost=on -device e1000,netdev=hostnet0,id=net0,mac=00:1a:4a:42:0b:38,bus=pci.0 -vnc :10 -k en-us -vga std -monitor stdio -chardev socket,path=/tmp/serial3,server,nowait,id=serial3 -chardev socket,path=/tmp/serial4,server,nowait,id=serial4 -chardev socket,path=/tmp/serial5,server,nowait,id=serial5 --nodefaults -chardev socket,path=/tmp/serial6,server,nowait,id=serial6 -chardev socket,path=/tmp/serial7,server,nowait,id=serial7 -chardev socket,path=/tmp/serial8,server,nowait,id=serial8 -chardev socket,path=/tmp/serial9,server,nowait,id=serial9 -qmp tcp:0:5888,server,nowait 2.install qemupciserial.inf 3.hotplug pci-serial,pci-serial-2x,pci-serial-4x (qemu) device_add pci-serial,chardev=serial3,id=aa3 (qemu) device_add pci-serial-2x,chardev1=serial4,chardev2=serial5,id=aa4 (qemu) device_add pci-serial-4x,chardev1=serial6,chardev2=serial7,chardev3=serial8,chardev4=serial9,id=aa5 Actual results: pci-serial/pci-serial-2x/pci-serial-4x can be installed/hotplug successfully; but after step3,the communication ports in guest device manager were marked with a yellow exclamation(as shown in the first attachment); the ports became normal after reboot guest(as shown in the second attachment) Expected results: communication ports can works well without reboot guest.
