Equivalent Logical Slot for "Physical Slot 1 " is under domain 0x0000 ,Bus 0x00,Slot 0x09,Index[Bridge] 0x07

The Application has been hosted on VMware.

To maintain a Standard ,the Application has Defined Network Interfaces [for LAN segregation/functions & automation]

Currently I am trying to bring the Application on KVM,and the Network Interfaces have to be in a certain location for the Automation to work properly.

I need to have these Network Interfaces -pci2p1,pci2p2 & pci3p1,pci3p2.

Regards

Thiru

What is logical slot X vs. physical slot X? There are only two PCI
addresses associated with any PCI passthrough device (the slot on the
host, and the slot on the guest), which you say you aren't interested in
anyway, and there is only one PCI address associated with any emulated
device - the slot on the guest, which is set with the <address>
sub-element of any device. In general, whatever address you set there
will be the location of the device on the guest, although I've heard
some people mention that this isn't necessarily always the case, but
depends on the guest OS.

This should place the card in slot 5 of bus 0:

<interface type=....>
...
<address type='pci' domain='0' bus='0' slot='5' function='0'/>
</interface>

Showing up on a particular slot doesn't necessarily guarantee the name
that will be given to the interface - that is completely up to the guest
OS. For example, on my F19 hardware, I have an ethernet at bus=4 slot=0
function=0 which was given the name "p13p1", another at 4:0.1 which is
"p13p2", and another that is integrated on the motherboard at 6:0.0
which is named "p32p1". On several F19 guests (some installed with F19
from scratch, at least one upgraded from F18), the network interfaces
are all named ethX. I believe this is now somehow controlled by systemd,
but I haven't had any need to learn the details.
