Hi Mark,
I suggest you post questions about the XenServer product on the Citrix support forums at http://forums.citrix.com/category.jspa?categoryID=101 where a number of Citrix XenServer experts hang out.
For this specific question this is not a bug. As the error message states the VM has a constraint that dynamic_min, dynamic_max and static_max must all be equal. Your command is trying to change one of these values in isolation which would break this constraint. I suggest using the CLI command vm-memory-limits-set, e.g.: “xe vm-memory-limits-set uuid=e4f2d301-77d0-6c3f-055a-412f74b3920d dynamic-min=2GiB dynamic-max=2GiB static-max=2GiB static-min=2GiB”.
As an aside it’s worth pointing out that the memory constraints differ between the XenServer Free edition (which don’t have dynamic memory control enabled) “static_min <= dynamic_min = dynamic_max = static_max” and the XenServer paid editions (which do) “static_min <= dynamic_min <= dynamic_max <= static_max”.
Cheers,
James

Does Citrix know already about this issue? Not just the best quality of software ...
