the product is no longer active in Red Hat Bugzilla.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:
libvirt should output error when set a wrong ipv6 host id
Version-Release number of selected component (if applicable):
libvirt-1.2.8-16.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.prepare a network like this:
# virsh net-dumpxml ipv6
<network>
<name>ipv6</name>
<uuid>f8c22eeb-166a-4c5b-91a7-99c188b2c481</uuid>
<forward mode='nat'/>
<bridge name='virbr6' stp='on' delay='0'/>
<mac address='52:54:00:7f:f0:47'/>
<ip family='ipv6' address='2001:db8:ca2:2::1' prefix='64'>
<dhcp>
<range start='2001:db8:ca2:2:1::10' end='2001:db8:ca2:2:1::ff'/>
<host id='0:4:7e:7d:f0:7d:a8:bc:c5:d2:13:32:11:ed:16:ea:84:f3' ip='2001:db8:ca2:2:3::4'/>
</dhcp>
</ip>
<route family='ipv6' address='2001:db8:ca2:2::' prefix='65' gateway='2001:db8:ca2:2:1::10'/>
</network>
2. edit host id like this(change 'f' to 'z'):
<host id='0:4:7e:7d:f0:7d:a8:bc:c5:d2:13:32:11:ed:16:ea:84:z3' ip='2001:db8:ca2:2:3::4'/>
3.# virsh net-edit ipv6
Network ipv6 XML configuration edited.
4.check the libvirtd.log
2015-02-17 08:02:19.007+0000: 22613: error : virNetworkDHCPHostDefParseXML:731 : XML error: Invalid character 'z' in id '0:4:7e:7d:f0:7d:a8:bc:c5:d2:13:32:11:ed:16:ea:84:g3' of network 'ipv6'.
Actual results:
An error happened when parse the xml , but libvirt do not output it
Expected results:
libvirt should output error when set a wrong ipv6 host id, we already check this why not output the error and stop parse.

conf: error out on invalid host id
https://bugzilla.redhat.com/show_bug.cgi?id=1196503
We already check whether the host id is valid or not, add a jump
to forbid invalid host id.
