Lack of swap may be an issue here. Qmemman needs some time to assign
more RAM (*) and this is the reason why VMs in Qubes have swap by
default enabled.
If you need a lot of RAM allocated quickly (for example it applies for
Android build), better assign it initially and disable memory balancing
for this VM.

(*) Actually there are two parts of this: first detecting that qube
needs more RAM - it is reported with 10Hz frequency, as a trade-off
between allocation speed and system load caused by qmemman itself.
Secondly, it needs some time to actually get this memory, potentially
reclaiming it from other qubes first.
