Fix included in qemu-kvm-rhev-2.1.0-3.el7 Reproduce this bug as follow version: Host: # uname -r 3.10.0-144.el7.x86_64 # rpm -q qemu-kvm-rhev qemu-kvm-rhev-1.5.3-60.el7_0_0.6.x86_64 Steps: 1.Boot guest with two virtio serial port use the same name ... -device virtio-serial-pci,id=virtio-serial0,max_ports=16 \ -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait \ -device virtserialport,chardev=channel1,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port1 \ -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait \ -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2 \ Results: Guest can boot up Verify this bug as follow version: Host: # uname -r 3.10.0-144.el7.x86_64 # rpm -q qemu-kvm-rhev qemu-kvm-rhev-2.1.0-3.el7.x86_64 Steps as same as reproduce Results: QEMU 2.1.0 monitor - type 'help' for more information (qemu) qemu-kvm: -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2: virtio-serial-bus: A port already exists by name com.redhat.rhevm.vdsm qemu-kvm: -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2: Device 'virtserialport' could not be initialized According to above test ,this bug has been fixed.

Description of problem: windows guest use the name transfer data, but qemu-kvm now can boot up different virtio serial port use the same name. Version-Release number of selected component (if applicable): host:RHEL6.5-20130820.2 qemu-kvm-0.12.1.2-2.398.el6.x86_64 kernel-2.6.32-414.el6.x86_64 guest: win7-64 virtio-win-prewhql-0.1-68 How reproducible: 100% Steps to Reproduce: 1. try boot up guest with two virtio serial port use the same name ... -device virtio-serial-pci,id=virtio-serial0,max_ports=16 \ -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait \ -device virtserialport,chardev=channel1,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port1 \ -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait \ -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2 \ 2. 3. Actual results: can boot up guest (qemu)info qtree ... bus: virtio-serial0.0 type virtio-serial-bus dev: virtserialport, id "port2" dev-prop: chardev = channel2 bus-prop: nr = 2 bus-prop: name = "com.redhat.rhevm.vdsm" dev-prop-int: id: 2 dev-prop-int: guest_connected: 0 dev-prop-int: host_connected: 0 dev-prop-int: throttled: 0 dev: virtserialport, id "port1" dev-prop: chardev = channel1 bus-prop: nr = 1 bus-prop: name = "com.redhat.rhevm.vdsm" dev-prop-int: id: 1 dev-prop-int: guest_connected: 0 dev-prop-int: host_connected: 0 dev-prop-int: throttled: 0 ... Expected results: qemu-kvm quit with warning, like boot up devices use the same id. Additional info:
