Description
Hide button from virt-manager GUI since qemu-kvm not supported:parallel device and smardcard device with host mode.

Version:
virt-manager-0.10.0-7.el7.noarch

How reproducible:
100%

Steps to Reproduce:
1. Check the device which qemu-kvm supports,listed the result in additional info.
# /usr/libexec/qemu-kvm -device ? 

2. Check the result,there is no parallel device.

3. From virt-manager GUI,you can find parallel device.If you add it then try to boot the guest,error will show:

Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device isa-parallel,chardev=charparallel0,id=parallel0: Parameter 'driver' expects device type


4. Check other devices,ccid-card-emulated is not there,so smardcard with host mode is not supported on rhel7.
Try to boot guest with smardcard host mode will meet error:

Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device ccid-card-emulated,backend=nss-emulated,id=smartcard0,bus=ccid0.0: Parameter 'driver' expects device type

Actual results：
As description.

Expected results:
Hidden button from virt-manager GUI since qemu-kvm not supported:parallel device and smardcard host mode.

Comment 2 tingting zheng 2013-12-06 08:56:16 UTC

Also virtio-9p-device and virtio-9p-pci are not supported from qemu-kvm,so when try to add FileSystem on virt-manager,error will show: 

Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=/mnt,bus=pci.0,addr=0x7: Parameter 'driver' expects device type

Comment 6 hyao@redhat.com 2014-01-06 05:47:01 UTC

I can reproduce it on 
rpm -qa libvirt virt-manager
libvirt-1.1.1-17.el7.x86_64
virt-manager-0.10.0-9.el7.noarch

1. From virt-manager GUI,you can find parallel device.If you add it then try to boot the guest,error will show:

Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device isa-parallel,chardev=charparallel0,id=parallel0: Parameter 'driver' expects device type


2. Check other devices,ccid-card-emulated is not there,so smardcard with host mode is not supported on rhel7.
Try to boot guest with smardcard host mode will meet error:

Error starting domain: internal error: early end of file from monitor: possible problem:
qemu-kvm: -device ccid-card-emulated,backend=nss-emulated,id=smartcard0,bus=ccid0.0: Parameter 'driver' expects device type

Comment 7 zhengqin 2014-03-11 03:26:06 UTC

Please pay attention to one point:

Since install guest by cdrom is not supported by qemu-kvm, we should remove cdrom installation option from virt-manager when install qemu/kvm guest.


2 places should be changed on "New VM" window for create qemu/kvm guest with virt-manager:

A. Remove "or CDROM" from installation option "Local install media(ISO image or CDROM)"  on "Step1 of 5" window;
B. Remove installation option "Use CDROM or DVD" on "Step 2 of 5" window.


Thanks.

Comment 9 Giuseppe Scrivano 2014-06-09 10:54:40 UTC

since there is no way to query which devices are supported by libvirt so to display only those supported and that these options can be used with the upstream version of libvirt/qemu, I think we should leave them in virt-manager and rely on the error message.
