I use /omap2plus_defconfig/ . Yes , device tree support is there and
the dts file used is /omap5-uevm.dts

Is there a way to debug which one of the above two possibilities has
lead to the issue ?
Four years ago I did it in a following way:
- wire up to UART2 pins on an expansion connector (this sheet might
be useful for you: http://www.ti.com/lit/ug/swcu130/swcu130.pdf)
- assign UART2 IOMEM ranges to DomU
- enable in domu kernel earlyprintk and patch it to output to omap
UART2
Nowadays assigning UART2 IOMEM ranges might be a bit more complex due to
XEN evolution.
Another way is to use JTAG which understands virtualization, and allows
you to debug DomU.
