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.

Version-Release number of selected component (if applicable):
python-virtinst-0.500.5-3.el6.noarch

How reproducible:
always

Steps to Reproduce:
1.# virt-install -n demo -r 512 -f /tmp/img/rhel6_x86_64_qcow2.img --import --security type=static,label='system_u:object_r:svirt_image_t:s0:c100,c200'

2.#virsh dumpxml demo

  
Actual results:
........
<seclabel type='dynamic' model='selinux'>
    <label>system_u:system_r:svirt_t:s0:c67,c414</label>
    <imagelabel>system_u:object_r:svirt_image_t:s0:c67,c414</imagelabel>
  </seclabel>
........

security type should be 'static', and the label is same with settings by user.


Additional info:
Comment 1 Cole Robinson 2011-06-10 19:45:25 UTC 
Please provide the output of virt-install --debug (also please do so for any future virt-* bug reports)
Comment 2 Cole Robinson 2011-06-10 19:51:37 UTC 
Actually, I can reproduce, so no need for --debug output
Comment 3 Cole Robinson 2011-07-14 02:14:43 UTC

Comment 4 Cole Robinson 2011-07-28 15:34:30 UTC 
Fixed in python-virtinst-0.600.0-1.el6
Comment 6 Huming Jiang 2011-08-02 08:51:54 UTC 
Could still reproduce this bug in the following componets:
python-virtinst-0.600.0-1.el6.
libvirt-0.9.4-0rc1.el6.x86_64
kernel-2.6.32-171.el6.x86_64
qemu-kvm-0.12.1.2-2.174.el6.x86_64
How reproducible:
always

Steps to Reproduce:

# virt-install -n demo -r 512 -f /var/lib/libvirt/images/demo.img -s 5 -c /dev/cdrom  --security type=static,label='system_u:object_r:svirt_image_t:s0:c100,c200'

Starting install...
ERROR    internal error Process exited while reading console log output: libvir: error : cannot execute binary /usr/libexec/qemu-kvm: Permission denied

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

When i reproduced this bug use the above packages, I met the following problem, so whether this bug has been fixed or not is unknown for me(Sorry for comment 6 ). The following error message is a new problem about this bug. So set the bug status to ASSIGNED.

Comment 8 Cole Robinson 2011-08-02 14:55:57 UTC 
The initial report said that even if the user specified --security type=static we would still generate XML with type=dynamic. You should be able to confirm that virt-install did the correct thing by specifying --debug and checking that the generated XML has <seclabel type='static' in it.

That said, there might be other issues here, but those would be separate bugs.
Comment 9 Huming Jiang 2011-08-03 10:36:02 UTC 
verified with the following components:
python-virtinst-0.600.0-2.el6.noarch
libvirt-0.9.4-0rc1.2.el6.x86_64
qemu-kvm-0.12.1.2-2.175.el6.x86_64
kernel-2.6.32-171.el6.x86_64

Steps:
1.chcon system_u:object_r:svirt_image_t:s0:c100,c200 /var/lib/libvirt/images/test.img
2. virt-install -n test -r 512 -f /var/lib/libvirt/images/test.img --import --security type=static,label='system_u:system_r:svirt_t:s0:c100,c200' --debug

...
  <seclabel type='static' model='selinux' relabel='no'>
    <label>system_u:system_r:svirt_t:s0:c100,c200</label>
  </seclabel>
...

3. virsh dumpxml test

...
  <seclabel type='static' model='selinux' relabel='no'>
    <label>system_u:system_r:svirt_t:s0:c100,c200</label>
  </seclabel>
