1141621 – libvirtd will crashed after hot-plug a virtual NIC to a guest which use qemu-attach connect to libvirtd

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 of problem:
libvirtd will crashed after hot-plug a virtual NIC to a guest which use qemu-attach connect to libvirtd

Version-Release number of selected component (if applicable):
libvirt-1.2.8-2.el7.x86_64
qemu-kvm-rhev-2.1.0-3.el7.x86_64

How reproducible:
100%

Steps to Reproduce:

1.[root@localhost ~]#  /usr/libexec/qemu-kvm -cdrom /tmp/test.iso                     -monitor unix:/tmp/demo,server,nowait                     -name sdsd2                     -uuid cece4f9f-dff0-575d-0e8e-01fe380f12ef  &

[3] 30013
[root@localhost ~]# VNC server running on `::1:5901'

2.[root@localhost ~]# virsh qemu-attach 30013
Domain sdsd2 attached to pid 30013

3.[root@localhost ~]# virsh attach-interface sdsd2 network default
error: Failed to attach interface
error: End of file while reading data: Input/output error
error: Failed to reconnect to the hypervisor

4.check libvirtd pid changed


Actual results:
libvirtd crashed after hot-plug a virtual NC

Expected results:
report error or attach success

Comment 10 Luyao Huang 2014-11-08 05:40:25 UTC

Hi John,

During i do some extend test for qemu-attach, i found another crash,
Should i open another bug or just fix it in this bug?thanks.

Steps:

# /usr/libexec/qemu-kvm -m 512 -hda /var/lib/libvirt/images/test6.img -net nic -net tap,vlan=0,ifname=tap0,script=no --daemonize -monitor unix:/tmp/demo,server,nowait -vnc 127.0.0.1:2 -name sdsd2

# virsh qemu-attach 22094
Domain sdsd2 attached to pid 22094

# virsh screenshot sdsd2
error: could not take a screenshot of sdsd2
error: End of file while reading data: Input/output error
error: Failed to reconnect to the hyperviso
