It's likely a pci-serial vs. isa-serial device getting created. Something
like
-device pcie-root-port,port=0xa,chassis=3,id=pci.3,bus=pcie.0,addr=0x1.0x2 \
-chardev stdio,logfile=logfile,id=chardev0,logappend=off \
-device pci-serial,chardev=chardev0,bus=pci.3,addr=0x0
works for me, but only with upstream (not RHEL) qemu, and when adding
console=ttyS0 to the guest kernel command line.
That's using QEMU directly though, right?
Because the default for libvirt is to use isa-serial and you
would have to tell it explicitly to use pci-serial instead,
with
<serial type='pty'>
<target type='pci-serial' port='0'/>
</serial>
My point is that you or Christoffer having configured your
QEMU binary differently shouldn't be enough to affect the
command line generated by libvirt.
