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,
