Description yalzhang@redhat.com 2016-02-24 10:12:02 UTC 
Description of problem:
libvirt will crash when start a guest with hostdev type network whose interface pool specified with a list of <interface> elements (currently only support <address> elements) 

Version-Release number of selected component (if applicable):
libvirt-1.3.1-1.el7.x86_64

How reproducible:


Steps to Reproduce:
1.Setup SR-IOV
[root@ibm-x3850x5-05 tmp]# virsh nodedev-list --tree
 +- pci_0000_80_01_0
  |   |
  |   +- pci_0000_86_00_0
  |   |   |
  |   |   +- net_eth2_90_e2_ba_30_79_5c

  |   |     
  |   +- pci_0000_86_10_0
  |   |   |

  |   |     
  |   +- pci_0000_86_10_5
  |       |
  |       +- net_eth5_62_8c_c3_60_ed_20
  |         

2. Define and start a network with forward mode=hostdev and interface pool specified with VF's name which is not supported currently.
[root@ibm-x3850x5-05 tmp]# cat testnet.xml
<network>
<name>testnet</name>
<forward dev='eth4' mode='hostdev' managed='yes'>
<driver name='vfio'/>
<interface dev='eth4'/>
<interface dev='eth7'/>
<interface dev='eth8'/>
<interface dev='eth9'/>
</forward>
</network>
[root@ibm-x3850x5-05 tmp]# virsh net-define testnet.xml
Network testnet defined from testnet.xml
[root@ibm-x3850x5-05 tmp]# virsh net-start testnet
Network testnet started

3. Start a guest with source network=testnet, the libvirtd crash and restart with a new pid.
[root@ibm-x3850x5-05 tmp]# virsh dumpxml rhel7.2 | grep /interface -B5
    <interface type='network'>
      <mac address='52:54:00:1b:6f:e5'/>
      <source network='testnet'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>
[root@ibm-x3850x5-05 tmp]# pidof libvirtd
4367
[root@ibm-x3850x5-05 tmp]# virsh start rhel7.2
error: Disconnected from qemu:///system due to I/O error
error: Failed to start domain rhel7.2
error: End of file while reading data: Input/output error

error: One or more references were leaked after disconnect from the hypervisor
[root@ibm-x3850x5-05 tmp]# pidof libvirtd
5977

4. Start a guest, then attach an interface in the previous defined network.
[root@ibm-x3850x5-05 tmp]# pidof libvirtd
5977
[root@ibm-x3850x5-05 tmp]# virsh attach-interface rhel7.2 --type network --source testnet
error: Disconnected from qemu:///system due to I/O error
error: Failed to attach interface
error: End of file while reading data: Input/output error

error: One or more references were leaked after disconnect from the hypervisor
[root@ibm-x3850x5-05 tmp]# pidof libvirtd
6473
[root@ibm-x3850x5-05 tmp]# 


Actual results:
libvirt crashed with illegal operation.

Expected results:
libvirt should not crash.

Comment 6 Laine Stump 2017-03-26 23:57:11 UTC
