Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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:
Actually , this problem from a mistake. Just wanna access image with host name from gluster server , but forgot add host name and ip address into /etc/hosts. then try boot up guest will segmentation fault.
Version-Release number of selected component (if applicable):
host: RHEL6.5-20130804.n.0
qemu-kvm-tools-0.12.1.2-2.385.el6.g11.x86_64
gpxe-roms-qemu-0.9.7-6.9.el6.noarch
qemu-kvm-0.12.1.2-2.385.el6.g11.x86_64
qemu-img-0.12.1.2-2.385.el6.g11.x86_64
kernel-2.6.32-411.el6.x86_64
gluster server: RHS-2.1-20130806.n.2
glusterfs-server-3.4.0.17rhs-1.el6rhs.x86_64
How reproducible:
100%
Steps to Reproduce:
1. [root@m-qz ~]# ping gluster-server
ping: unknown host gluster-server
2. boot up guest with:
...
-netdev tap,id=hostnet0,vhost=on \
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:39:13:2c \
-drive file=gluster://gluster-server/vol/rhel6u5.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,werror=stop,rerror=stop,aio=threads \
-device virtio-blk-pci,scsi=off,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=0 \
Actual results:
qemu-kvm segmentation fault.
Program received signal SIGSEGV, Segmentation fault.

Expected results:
quit with warning.
Additional info:
add ip address and host name in to "/etc/hosts", will works well.
verify this bug with new package.
