Re: [libvirt] [PATCH] Set a sensible default master start port for ehci companion controllers



Hey,

I built libvirt RPM with this fix (and the previous addresses fix), and I get the following error when running a VM with USB support:
internal error Process exited while reading console log output: qemu-kvm: -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x4.0x7: Duplicate ID 'usb' for device

This error happened also without these fixes (I thought these patches will address that, so I waited, but looks like the problem might not be related to it).

Did you encounter such a problem when you tested it?

The relevant devices I pass are:
      <controller index="0" model="ich9-ehci1" type="usb"/>
      <controller index="0" model="ich9-uhci1" type="usb">
              <master startport="0"/>
      </controller>
      <controller index="0" model="ich9-uhci2" type="usb">
              <master startport="2"/>
      </controller>
      <controller index="0" model="ich9-uhci3" type="usb">
              <master startport="4"/>
      </controller>
      <redirdev bus="usb" type="spicevmc"/>
      <redirdev bus="usb" type="spicevmc"/>

Thank you,
Oved
