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.
