A way to work around the issue is to use the VirtIO-based
console instead:
<console type='pty'>
<log file='...'/>
<target type='virtio'/>
</console>
However, that has its own drawbacks, such as not being able
to access early boot or even the bootloader.
Cole just posted some patches for this upstream: https://www.redhat.com/archives/libvir-list/2017-June/msg01128.html The fix has now been merged upstream.

qemu: command: support -chardev for platform devices
Some qemu arch/machine types have built in platform devices that
are always implicitly available. For platform serial devices, the
current code assumes that only old style -serial config can be
used for these devices.
Apparently though since -chardev was introduced, we can use -chardev
in these cases, like this:
-chardev pty,id=foo
-serial chardev:foo
Since -chardev enables all sorts of modern features, use this method
for platform devices.

Configuring a guest with <console type='pty'> <log file='...'/> </console> fails on aarch64 with error: unsupported configuration: logfile not supported in this QEMU binary The underlying issue is that, unlike what happens for x86 and ppc64, the guest-side serial console (pl011) is instantiated implicitly, even when -nodefaults is used, so libvirt doesn't have a way to assign it a chardev with the logfile property configured.
