[Xen-devel] xl: insufficient ballooning when starting certain guests

["Jan Beulich" <JBeulich@xxxxxxxx>]

Tools maintainers,

it looks as if changes in the memory requirements of the hypervisor
have pushed things over the border of not working anymore when
passing through a device and not sharing page tables (between VT-d
and EPT, or unconditionally on AMD). Since this has always been a
latent issue (as it's quite obvious that two sets of page tables require
more memory than a single set) it should imo be fixed. The main issue
(afaics) here is that the information about whether sharing is in use
is not currently available to the tools (ignoring the awkward option of
parsing the hypervisor log). Therefore the question is - should we
extend XEN_SYSCTL_physinfo accordingly, or are there other
suitable means to communicate such information which I'm not
(immediately) aware of?

Thanks, Jan
