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 Xuesong Zhang 2013-08-29 08:15:01 UTC 
Clone bug 1002427 to rhel7, since the issue also appear in rhel7.

libvirt-1.1.1-2.el7.x86_64

+++ This bug was initially created as a clone of Bug #1002427 +++

Description of problem:
libvirt should forbid hot-plug interface of inactive network with forward mode 'hostdev'.

Version-Release number of selected component (if applicable):
libvirt-0.10.2-23.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. prepare one hostdev network like the following one.
# virsh net-dumpxml hostdev-net1
<network>
  <name>hostdev-net1</name>
  <uuid>a57d0acb-3182-28ad-5c47-aae471ca8084</uuid>
  <forward mode='hostdev' managed='yes'>
    <address type='pci' domain='0x0000' bus='0x11' slot='0x10' function='0x0'/>
    <address type='pci' domain='0x0000' bus='0x11' slot='0x10' function='0x1'/>
  </forward>
</network>

2. make sure the network are all in inactive status.
# virsh net-list --all
Name                 State      Autostart     Persistent
--------------------------------------------------
default              inactive   no            yes
hostdev-net1         inactive   no            yes

3. prepare one running guest.
# virsh start r6
Domain r6 started

4. hot-plug the interface in hostdev network.
# virsh attach-device r6 vfpool.xml 
Device attached successfully

5. hot-plug the interface in default pool.
# virsh attach-device r6 default-pool-NIC.xml 
error: Failed to attach device from default-pool-NIC.xml
error: internal error Network 'default' is not active.


Actual result:
In step4, hot-plug the interface of inactive hostdev network will be successfully.

Expected result:
In step4, libvirt should forbid to hot-plug the interface of inactive network, such as the step 5.
Comment 2 Xuesong Zhang 2013-08-29 08:29:20 UTC 
This issue also appear while cold-plug.

1. prepare the following 2 xml.
#cat defalut-NIC.xml
<interface type='network'>
      <source network='default'/>
</interface>
#cat hostdev-NIC.xml
<interface type='network'>
      <source network='hostdev-net1'/>
</interface>

2. make sure both the default and hostdev network are inactive.
# virsh net-list --all
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 default              inactive   yes           yes
 hostdev-net1         inactive   no            yes

3. cold-plug the defalut-NIC.xml to the shutoff guest, then start the guest.
# virsh start rhel7raw
error: Failed to start domain rhel7raw
error: internal error: Network 'default' is not active.

4. remove the default-NIC.xml from guest xml, and cold-plug the defalut-NIC.xml to the shutoff guest, then start the guest.
# virsh start rhel7raw
Domain rhel7raw started

Expected result:
In step4, the guest should forbid to start the guest and report error like step3.
