1038926 – Hide button from virt-manager GUI since qemu-kvm not supported

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description tingting zheng 2013-12-06 07:29:39 UTC

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.
