Description of problem: libvirt should verify proper address family of <host> when updating network Version-Release number of selected component (if applicable): libvirt-1.2.8-15.el7.x86_64 How reproducible: 100% Steps to Reproduce: [root@ibm-x3850x5-06 ~]# cat ip-dhcp-host.xml <host mac='52:54:00:cb:17:00' name='jiahu.example.com' ip='192.168.122.10'/> [root@ibm-x3850x5-06 ~]# cat ipv6-dhcp-host.xml <host id='00:04:58:fd:e4:15:1b:09:4c:0e:09:af:e4:d3:8c:b8:ca:1e' name="redhatipv6.redhat.com" ip='2001:db8:ca2:2::119'/> [root@ibm-x3850x5-06 ~]# virsh net-update default add-first ip-dhcp-host ipv6-dhcp-host.xml --parent-index 0 Updated network default live state [root@ibm-x3850x5-06 ~]# virsh net-dumpxml default <network> <name>default</name> <uuid>6d4f9a7b-d8bc-4150-a891-46019e4c99a5</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr0' stp='on' delay='0'/> <mac address='52:54:00:42:e5:99'/> <domain name='example.com'/> <dns> <forwarder addr='8.8.8.8'/> <forwarder addr='8.8.4.4'/> <txt name='hjw' value='redhat jiahu'/> </dns> <ip address='192.168.122.1' netmask='255.255.0.0'> <dhcp> <range start='192.168.1.2' end='192.168.5.254'/> <host id='00:04:58:fd:e4:15:1b:09:4c:0e:09:af:e4:d3:8c:b8:ca:1e' name='redhatipv6.redhat.com' ip='2001:db8:ca2:2::119'/> </dhcp> </ip> <ip family='ipv6' address='2001:db8:ca2:2::1' prefix='64'> <dhcp> <range start='2001:db8:ca2:2::100' end='2001:db8:ca2:2::1ff'/> </dhcp> </ip> </network> Actual results: As shown above steps. Expected results: Should prevent such behavior. Additional info: [root@ibm-x3850x5-06 ~]# virsh net-update default delete ip-dhcp-host ip-dhcp-host.xml --parent-index 1 error: Failed to update network default error: XML error: Invalid to specify MAC address '52:54:00:cb:17:00' in network 'default' IPv6 static host definition Laine has sent a candidate patch to upstream. https://www.redhat.com/archives/libvir-list/2015-January/msg00670.html
This patch was pushed upstream: commit 6a21bc119e37bafcbe5cfd13e57080d651296b43 Author: Laine Stump <laine@laine.org> Date: Mon Jan 19 17:04:01 2015 -0500 network: verify proper address family in updates to <host> and <range>
Verify this bug with libvirt-1.2.17-7.el7.x86_64 1. Prepare a network # virsh net-dumpxml default6 <network> <name>default6</name> <uuid>999fc2e3-a6e4-49a4-b7c2-0bf186ca182a</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr1' stp='on' delay='0'/> <mac address='52:54:00:2d:3a:21'/> <ip address='192.168.123.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.123.2' end='192.168.123.254'/> </dhcp> </ip> <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'/> </dhcp> </ip> </network> 2. Prepare a xml file # cat ipv6-host.xml <host id='00:04:58:fd:e4:15:1b:09:4c:0e:09:af:e4:d3:8c:b8:ca:1e' name="redhatipv6.redhat.com" ip='2001:db8:ca2:2::119'/> 3. Update network #virsh net-update default6 add-first ip-dhcp-host ipv6-host.xml --parent-index 0 error: Failed to update network default6 error: Requested operation is not valid: the address family of a host entry IP must match the address family of the dhcp element's parent So this bug can be verified.
