Hi Grzegorz,

Is it possible / supported / planned to run a client OS without
specifying RAM/HDD up-front but with dynamically allocated resources?

 The amount of RAM specified is just the maximum allowed, and by default
is demand-paged without any pre-allocation.

 For disk, the same effect can be achieved by using a sparse volume,
e.g. 'truncate -s <disk-siz>' on UFS.

And if your using ZFS on the host you can create a sparse zvol with

zfs create -sV <disk-size> zpool/guestvol
