Guest Xml
======= ISSUE ======= Defining a network filter and Starting a VM with this nwfiter in VM's xml is failing with "cause is unknown".
================== Recreation Steps ==================
1. Define a network filter as: virsh nwfilter-define filter.xml
2. Add nwfilter in guest xml and start guest. virsh start VM1
It fails with : # virsh start VM1 error: Failed to start domain VM1 error: An error occurred, but the cause is unknown
XML used for defining network filter: ```<?xml version='1.0' encoding='UTF-8'?> <filter chain="root" name="clean-traffic" priority=""> <uuid>11111111-b071-6127-b4ec-111111111111</uuid> <filterref filter="no-mac-spoofing" /><filterref filter="no-ip-spoofing" /><filterref filter="allow-incoming-ipv4" /><filterref filter="no-arp-spoofing" /><filterref filter="qemu-announce-self" /><rule action="accept" direction="out" priority="-650" statematch="None"> <mac protocolid="ipv4" /></rule><rule action="accept" direction="inout" priority="-500" statematch="None"> <mac protocolid="arp" /></rule></filter> ```
will be attaching the guest xml
The issue happens with Ubuntu 18.04 host - where not able to start the guest with network defined with value dhcp.
<parameter name='CTRL_IP_LEARNING' value='dhcp'/> . Found following commit is not there in 18.04 Ubuntu source. There could be some dependent commit too. we are facing some build issue and hence not able to verify it. . https://github.com/libvirt/libvirt/commit/e62cb4a9b78c7f4499a206635fb4f06e6ac627e5 .
