But how we can add more memory to guest VM in realtime, than was at boot

Can we somehow make balloon inflated at start time? (F.e. VM starts with
memory = 512Mb and balloon inflating to +512Mb).

Yes, you can do that, and it took me a while to find out how. In your config file put something like this :
memory  = '512'
maxmem  = '1024'

As I understnad it, it will start the guest with (in this example) 512M of RAM, but you can use "xm mem-set nnn" to increase that within the bounds of the maxmem setting. If increasing, the extra memory is hotplugged into the client. When decreasing, I assume there is a process for getting the client to free up the memory before it is hotplug removed.
