Xen users - Sep 2012 - xen-hypervisor and dynamic memory?

Dear Xen List,


I am new to xen and have successfully setup a dom-0 and some dom-Us. The 
only drawback is that I''d like to assign a fixed minimum amount of 
memory to the dom-Us and allow them to make dynamic use of still 
available memory (like a memory pool).

Is this possible at all with xen-hypervisor? (I didn''t find any
solutions)

Best regards,


Eddy

Short answer: no.

Long answer: probably yes, if you use tmem-enabled kernels. This
thread (and the links in it) probably gives most info:
