hello,

I have a question about network devices ??

on my systems Centos 7.5 I have a Problem with starting Network devices!

I set up two servers with KVM on the first I have 6 KVM installed Systems on the second I have 5 KVM installed systems?

When I have to reboot my system (Kernel update....) the most time one Network Device is missing on the KVM Clients (eth0)

I have configured my system with I/O Shared Network like this

xxx.xml

<interface type='hostdev' managed='yes'> <mac address='XX:XX:XX:XX:XX:XX'/> <source> <address type='pci' domain='0x0000' bus='0x03' slot='0x13' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/> </interface>

and a second one! <interface type='hostdev' managed='yes'> ......... ............ This Interfaces are always starting

But I have also a Bridge on the systems (eth0) configure for internal Networking (DNS, LDAP.....)

<interface type='bridge'> <mac address='XX:XX:XX:XX:XX:XX'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface>

This interface is failing the most time on some KVM Installs!!

I have always to check is the Interface starting or not??

AFter 2 or 3 reboot with

virsh reboot xxxxx

the system is starting most time with the third Interface !

Can any tell me why this Problem exist??

Thanks for a answer,
