Hi,
the higher load is neither bound to memory increase nor Xen version, it's the kernel.
Changed at the same time from a Xenified 2.6.34.7 kernel to pvops jeremy's git
stable-2.6.32.x
Konrad, are you interested? You can see from attached graphic the much higer load
mid 21 to 24. riker (yellow) is using the cards constantly for scanning transponders,
two seem to make use of DMA for that reason...
Carsten.

Betreff: Load increase after memory upgrade?
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.
