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:
libvirtd crashed when use virt-install to create a lxc container

versions:
kernel-3.10.0-461.el7.x86_64
virt-install-1.4.0-1.el7.noarch

How reproduced:
100%

Steps:
(Some machines cannot reproduce this issue, and when I uninstall&reinstall libvirt and reboot host, it reproduced.)

terminal one:
	# gdb -p `pidof libvirtd`

terminal two:
	#virt-install --connect lxc:/// --name avocado-vt-vm3 --ram 500 --noautoconsole
	WARNING  No operating system detected, VM performance may suffer. Specify an OS with --os-variant for optimal results.

	Starting install...
	ERROR    End of file while reading data: Input/output error
	Domain installation does not appear to have been successful.
	If it was, you can restart your domain by running:
	  virsh --connect lxc:/// start avocado-vt-vm3
	otherwise, please restart your installation.



terminal one: libvirtd crashed with following backtrace

=====================================




Actual result:
libvirtd crashed



Expected result:
should not crashed





Additional info:
ON ABOVE HOST, when "setenforce 0", virt-install can be successful. 
BUT ON ANOTHER HOST, no matter setenforce 0/1, virt-install will crash libvirtd.

ANOTHER HOST: 
-kernel-3.10.0-382.el7.x86_64
-virt-install-1.4.0-1.el7.noarch
-libvirt-2.0.0-4.el7.x86_64

And backtrace on ANOTHER HOST as following:

    lxc: use job functions in lxcDomain{CreateXMLWithFiles, CreateWithFiles}
    
    Creating a large domain could potentially be time consuming.  Use the
    recently added job functions and unlock the virDomainObj while
    the create operation is in progress.
    
    Signed-off-by: Katerina Koukiou <k.koukiou>

virLXCDomainObjEndJob unconditionally dereferences the VM object and lxcDomainCreateXMLWithFiles has a code path that sets the vm object to NULL and then jumps to the 'endjob' label.

Hi Michal, 
bug 1351057 is on_qa and fixed in version libvirt-2.0.0-4.el7, but libvirtd still crashed with virt-install.
And that's why I open this bug. Pls help to confirm if it's should be set to "duplicate"

Verified on libvirt-2.0.0-5.el7
Crash not happened again, but virt-install still failed with selinux issue. So close this bug and open a new bug 1366485

steps:
1. virt-install a lxc container failed when setenforce 1
# setenforce 1
# virt-install --connect lxc:/// --name avocado-vt-vm1 --ram 500 --noautoconsole
WARNING  No operating system detected, VM performance may suffer. Specify an OS with --os-variant for optimal results.

Starting install...
ERROR    internal error: guest failed to start: Failure in libvirt_lxc startup: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
  virsh --connect lxc:/// start avocado-vt-vm1
otherwise, please restart your installation.

2. virt-install a lxc container succeeded when setenforce 0
# setenforce 0
# virt-install --connect lxc:/// --name avocado-vt-vm1 --ram 500 --noautoconsole
WARNING  No operating system detected, VM performance may suffer. Specify an OS with --os-variant for optimal results.

Starting install...
Creating domain...                                                                                                             |    0 B  00:00:00    
Domain creation completed.


During above steps, no crash happened.
