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 Gerd Hoffmann 2015-07-16 07:39:01 UTC 
+++ This bug was initially created as a clone of Bug #1211970 +++

Description of problem:
smart card emulation doesn't work with USB3 (nec-xhci) controller

Version-Release number of selected component (if applicable):
qemu-kvm-1.5.3-86.el7_1.1.x86_64

How reproducible:
always

Steps to Reproduce:
1. set up a VM with smartcard controller and USB3 controller:
    <controller type='usb' index='0' model='nec-xhci'/>
    <smartcard mode='passthrough' type='spicevmc'>
      <address type='ccid' controller='0' slot='0'/>
    </smartcard>
2. connect to the VM (virt-viewer $VM_NAME --spice-smartcard)
3.

Actual results:
smartcard emulation doesn't work. Examples of what is printed to qemu log with both QEMU_CCID_PASSTHRU_DEBUG and QEMU_CCID_DEBUG set to 4 is below

Expected results:
smartcard works just as it works with default controller (USB2 or in domain xml, ich9-ehci/ich9-uhci)

Comment 3 Miroslav Rezanina 2015-08-06 04:32:21 UTC 
Fix included in qemu-kvm-1.5.3-99.el7
Comment 5 Yanhui Ma 2015-08-13 09:29:56 UTC 
reproduce the issue:
host info:
3.10.0-302.el7.x86_64
qemu-kvm-1.5.3-86.el7.x86_64

steps:
1.boot up a rhel7.2 guest with smartcard controller and USB3 controller:
-device nec-usb-xhci -chardev spicevmc,name=smartcard,id=ccid -device usb-ccid -device ccid-card-passthru,chardev=ccid
2.in both host and guest
#yum groupinstall "smart card support"
 #yum remove '*openct*'
 #service pcscd start
3.plug in the reader before you run remote-viewer on host.
  remote-viewer --spice-smartcard spice://$IP:7000
4. open Smart Card Manager application in  guest

actual results:
Smart Card Manager application can not find the samrt card in guest.

verify the issue:
host info:
3.10.0-302.el7.x86_64
qemu-kvm-1.5.3-100.el7.x86_64

steps:
the same as above

actual results:
Smart Card Manager application can find the samrt card in guest.
Comment 6 Pei Zhang 2015-08-17 08:56:03 UTC 
Verify this issue from libvirt :

verify version:
libvirt-1.2.17-5.el7.x86_64
qemu-kvm-1.5.3-101.el7.x86_64

verify steps:

1.prepare env
both host and guest : 
# yum groupinstall "smart card support"
# service pcscd start 
Redirecting to /bin/systemctl start  pcscd.service

Plug physical smart card to host .
check in host :
Application ---> SystemTools ---> Smart Card Manager

2.define and start guest with following XML configuration.  

#virsh dumpxml r708 

usb3.0 controller:
<controller type='usb' index='0' model='nec-xhci'>
      <alias name='usb'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </controller>

ccid controller :
<controller type='ccid' index='0'>
      <alias name='ccid0'/>
    </controller>

smart card passthrough :
 <smartcard mode='passthrough' type='spicevmc'>
      <alias name='smartcard0'/>
      <address type='ccid' controller='0' slot='0'/>
    </smartcard>

spice graphic:
  <graphics type='spice' autoport='yes' listen='0.0.0.0'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>

2.1 check qemu cli, make sure guest's qemu cli like following  :
-device nec-usb-xhci,id=usb,bus=pci.0,addr=0x6 
-device usb-ccid,id=ccid0 
-chardev spicevmc,id=charsmartcard0,name=smartcard
-device ccid-card-passthru,chardev=charsmartcard0,id=smartcard0,bus=ccid0.0

3.start guest to check
#virsh start r708
#virsh domdisplay r708

3.2 using remote-viewer to check, must with "--spice-smartcard"
# remote-viewer --spice-smartcard spice://$host-IP:5901

check in guest :
Application ---> SystemTools ---> Smart Card Manager
smartcard enrolled.
