Re: [libvirt-users] avoiding PCI bus 8 / using PCI function / virt-install
Thanks. Maybe I'm missing something but when I try virt-install --dry-run
--print-xml it generates this snippet of XML:
<interface type="bridge">
<source bridge="ge_0_0_0_77"/>
<mac address="52:54:00:01:00:4e"/>
<model type="virtio"/>
</interface>
but what i need (and get from virsh dumpxml) has this extra PCI line.
<interface type='bridge'>
<mac address='52:54:00:01:00:4e'/>
<source bridge='ge_0_0_0_77'/>
<target dev='vnet78'/>
<model type='virtio'/>
<alias name='net78'/>
<address type='pci' domain='0x0000' bus='0x01'
slot='0x0a'
function='0x6' />
</interface>
Did I miss something? Do you see PCI in the XML when you do the
virt-install --dryrun approach?
Thanks

It won't do everything you want, but check out virt-install --print-step
--dry-run. This should at least allow you to get at the XML for the
intermediate steps and remove the brittleness of defining, destroying,
undefining the VM.
