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the product is no longer active in Red Hat Bugzilla.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:
Define/start a lxc without <console../> defined in xml. It is stopped by systemd soon. So libvirt should check the xml and forbid to start the container without console
Version-Release number of selected component (if applicable):
libvirt-1.2.8-5.el7.x86_64
3.10.0-189.el7.x86_64
systemd-208-14.el7.x86_64'
How reproducible:
100%

# virsh -c lxc:/// define lxc.xml
# virsh -c lxc:/// start lxc-test
Domain lxc-test started
2. check the lxc status
# virsh -c lxc:/// list --all
Id Name State
----------------------------------------------------
- lxc-test shut off
Actual result:
lxc without console can be started by libvirtd, but it is
stopped by systemd soon
Expected result:
libvirt should forbid to start the lxc without <console../> defining in xml

Require at least one console for LXC domain
A domain without a console quietly dies soon after start,
because we try to set /dev/null as a controlling TTY
2014-10-30 15:10:59.705+0000: 1: error : lxcContainerSetupFDs:283 :
ioctl(TIOCSCTTY) failed: Inappropriate ioctl for device
Report an error early instead of trying to start it.
