I'm noticing that VMs which have nwfilters associated with them
will apparently always cause the following errors to appear in
the logs upon VM shutdown:

2013-02-27 17:02:18.709+0000: 9669: error : virNWFilterDHCPSnoopEnd:2131 : internal error ifname "vnet0" not in key map
2013-02-27 17:02:18.715+0000: 9669: error : virNetDevGetIndex:653 : Unable to get index for interface vnet0: No such device

I got this trouble too on CentOS6.4 libvirt-0.10.2-18 , after vm started many seconds ,it will auto destroyed .

But I noticed that if remove the "

<hard_limit unit='KiB'>2097152</hard_limit>

<soft_limit unit='KiB'>2097152</soft_limit>

<swap_hard_limit unit='KiB'>3145728</swap_hard_limit>

</memtune>

" using virsh edit ,vm can start correctly.

below are error messages from /var/log/libvirt/libvirtd.log:
