Description of problem: nr=0 is reserved for virtconsole ,shouldn't be used for vioserialport .but it can be added if I exec device_add virtserialport twice Version-Release number of selected component (if applicable): 3.10.0-50.el7.x86_64 qemu-kvm-rhev-1.5.3-19.el7.x86_64 seabios-bin-1.7.2.2-4.el7.noarch sgabios-bin-0.20110622svn-3.el7.noarch seabios-1.7.2.2-4.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Start VM w/ virtio-serial-pci /usr/libexec/qemu-kvm -M pc-i440fx-rhel7.0.0 -cpu SandyBridge -enable-kvm -m 2G -smp 2,cores=2 -name bcao_win-7-32-netkvm -uuid 884e673a-1b4a-4385-a522-b3cc35ef4e18 -rtc base=localtime,clock=host,driftfix=slew -drive file=win8-64.qcow2,if=none,media=disk,serial=aaabbbccc,werror=stop,rerror=stop,cache=none,format=qcow2,id=drive-disk0 -device ide-drive,bus=ide.0,unit=1,physical_block_size=4096,logical_block_size=512,drive=drive-disk0,id=disk0 -drive file=/root/en_windows_8_enterprise_x64_dvd_917522.iso,if=none,media=cdrom,id=aa -device ide-drive,id=aa1,drive=aa,bootindex=1 -drive file=/usr/share/virtio-win/virtio-win.iso,media=cdrom,if=none,id=bb -device ide-drive,id=bb1,drive=bb -netdev tap,vhost=on,id=netdev0 -device e1000,netdev=netdev0,id=nic1,mac=1a:46:0b:ca:bc:7b -vnc :1 -vga std -monitor stdio -usb -device usb-tablet,id=tablet0 -global PIIX4_PM.disable_s3=0 -global PIIX_PM.disable_s4=0 -monitor unix:/tmp/tt,server,nowait -device virtio-serial-pci,id=serial0 -chardev socket,path=/tmp/socket,server,nowait,id=chardev0 -device virtserialport,id=port0,name=com.redhat.rhevm.vdsm,chardev=chardev0 2.(qemu)info qtree 3.(qemu)chardev-add socket,path=/tmp/socket1,server,nowait,id=chardev1 4.(qemu)device_add virtserialport,id=port1,name=com.redhat.test,chardev=chardev1,nr=0 5.(qemu)info qtree 6.Repeat step4 again 7.(qemu)info qtree Actual results: after step 2: dev: virtio-serial-pci, id "serial0" ioeventfd = on vectors = 2 class = 0x780 indirect_desc = on event_idx = on max_ports = 31 addr = 04.0 romfile = <null> rombar = 1 multifunction = off command_serr_enable = on class Class 0780, addr 00:04.0, pci id 1af4:1003 (sub 1af4:0003) bar 0: i/o at 0xc060 [0xc07f] bar 1: mem at 0xfebf1000 [0xfebf1fff] bus: virtio-bus type virtio-pci-bus dev: virtio-serial-device, id "" max_ports = 31 bus: serial0.0 type virtio-serial-bus dev: virtserialport, id "port0" chardev = chardev0 nr = 1 name = "com.redhat.rhevm.vdsm" port 1, guest off, host off, throttle off After step 3 , chardev can be added successfully After step 4 , It prompts "Port number 0 on virtio-serial devices reserved for virtconsole devices for backward compatibility. Device initialization failed. Device 'virtserialport' could not be initialized" After step5 ,results same as step2 After step6 ,it prompts "Property 'virtserialport.chardev' can't take value 'chardev1', it's in use" After step7 :it shows nr =4294967295 bus: virtio-bus type virtio-pci-bus dev: virtio-serial-device, id "" max_ports = 31 bus: serial0.0 type virtio-serial-bus dev: virtserialport, id "ཫCw" chardev = <null> nr = 4294967295 name = "com.redhat.test" port -1, guest off, host off, throttle off dev: virtserialport, id "port0" chardev = chardev0 nr = 1 name = "com.redhat.rhevm.vdsm" port 1, guest off, host off, throttle off Expected results: after step 6, results should same as after step4 After step7 ,results should same as after step2 & step5 Additional info: Try to boot guest w/ virtserialport with nr=0 ,failed to start .
