With line from device.map removed:

# grub-probe -t abstraction --device /dev/xvda1 -v
grub-probe: info: /dev/xvda1 starts from 0.
grub-probe: info: opening the device /dev/xvda.
grub-probe: error: cannot find a GRUB drive for /dev/xvda1.  Check your
device.map.

The result is different, but still does not work.

I have also tried to remove the (fake) /dev/xvda device. The result is:

# grub-probe -t abstraction --device /dev/xvda1 -v
grub-probe: info: /dev/xvda1 starts from 0.
grub-probe: info: opening the device /dev/xvda.
grub-probe: error: cannot find a GRUB drive for /dev/xvda1.  Check your
device.map.

When testing with devices.map entry, but fake xvda removed:

# grub-probe -t abstraction --device /dev/xvda1 -v
grub-probe: info: Cannot stat `/dev/xvda', skipping.
grub-probe: info: /dev/xvda1 starts from 0.
grub-probe: info: opening the device /dev/xvda.
grub-probe: error: cannot find a GRUB drive for /dev/xvda1.  Check your
device.map.

Anything else to test?
