[Xen-devel] Load increase after memory upgrade?

[Carsten Schiers <carsten@xxxxxxxxxx>]

Hi,

after my memory upgrade 4GB -> 8GB, I noticed a much higher load in the Video 
DomU, 
related to some PCI cards that do DMA. I could check that it's related to two 
of the
three cards that use the same hardware architecture (budget_av and budget_ci) 
whereas
the b2c2_flexcop doesn't show shuch a behaviour.

As I changed at the same time from Xen 4.1.0 to 4.1.1, I wondered whether this 
is

  a) normal or pathologic
  b) related to Xen or the memory upgrade

Any thoughts? Can be seen as the yellow domain in my munin graphs.

Carsten.
