I have a KVM guest which uses PCI passthrough for its network interfaces:
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x05' slot='0x00' function='0x0'/>
</source>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
</hostdev>
So there is no corresponding ifcfg-xxxx
file on host machine. Also guest is a proprietary OS, there is no way to capture traffic on it.
It it possible to capture network traffic via tcpdump from these interfaces on host?
