How should I add LD_PRELOAD to domain xml. I guess within:

<qemu:commandline>
     <qemu:arg value='env=LD_PRELOAD=/usr/lib64/libtcmalloc.so'/>
</qemu:commandline>

but this is generating syntax errors.

Note the bit in the example that shows:

    <qemu:env name='ID' value='wibble'/>

So try:

    <qemu:env name="LD_PRELOAD" value="/usr/lib64/libtcmalloc.so"/>
