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 liunana 2019-01-11 10:17:12 UTC 
Description of problem:
libvirt start guest failed with mdev device


Version-Release number of selected component (if applicable):
(host)
kernel-4.18.0-57.el8.x86_64
qemu-kvm-2.12.0-53.module+el8+2637+096d5272.x86_64
libvirt-4.5.0-17.module+el8+2625+db702f9d.x86_64
selinux-policy-targeted-3.14.1-49.el8.noarch


How reproducible:
6/6


Steps to Reproduce:
1. install a guest
2. start guest with medv device:

    <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci' display='on'>
      <source>
        <address uuid='5bb18984-3286-4242-87d3-e867450ce3c2'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </hostdev>

3.

Actual results:
guest can't be started with error logs[1], meanwhile journalctl get some error logs,I will attach them in comments.


Expected results:
guest can be start normally without any error


Additional info:
[1]
# virsh start rhel76 
error: Disconnected from qemu:///system due to end of file
error: Failed to start domain rhel76
error: End of file while reading data: Input/output error
Comment 1 yafu 2019-01-11 10:24:43 UTC 
It's a regression. Can not reproduced with ibvirt-4.5.0-16.el8.x86_64.
