Well, tools/examples/xmexample.hvm says xm supports `cpus=3D["2", "3"]`,
while on xl both syntax (with or without the inner `"`) are recognized
by xlu_get_list[item]().

TBH, I don't think it's worth distinguishing between the two, especially
considering we have the string syntax (i.e., `cpus=3D"2,3") to achieve the
current behaviour.

Indeed! :-)

Thanks and Regards,
