Backstory: Some [Unicode code points are invalid in XML][invalid]; specifically, we want to filter the code points (hex) 0-8, b-c, and e-1f. Qt4's QXmlStreamWriter() makes no attempt to filter these codepoints in the documents it writes.

So, here's our baseline, with the same benchmark we'll use later (big.gpx is a giant 142 MB file, and GPX is an XML-based format):

./gpsbabel -i gpx -f big.gpx [-o gpx -F /dev/null] (x5)

17.2 user, 4.8 system, 22.1 total

In [GPSBabel][], we already subclass QXmlStreamWriter to add other convenience methods. So our initial attempt to filter bad characters was simply to interpose on all methods that take potentially unfiltered inputs (writeAttribute(), writeTextElement(), ...) and apply a QString::replace() substitution with a QRegExp.

1) Deleted all vmware snapshots for the VM. sync. sync.
2) Followed rwmj's guide to setting up a br0 device for libvirt in Fedora.[0]
3) Grabbed vmware2libvirt[1] from Ubuntu (it's just a standalone python script) and
   used it with --bridge br0 -f foo.vmx > foo.xml.
4) Converted my vmdk to raw with qemu-img[2], moved it to /var/lib/libvirtd per
   instructions[3]
5) Edited my xml to point to the right disk, use the qemu/raw driver, use the right
   path for kvm (/usr/bin/qemu-kvm on Fedora).

5.a) Configure a unix socket serial device (like VMware's "pipe" mode):
