I applied the patches, but I haven't tested them ;) Perhaps Yu Ke can add some light here. > the other issue is dom0 memory...this is a bit odd... > system booted with dom0_mem=4096m but top displays only Mem: 2088992k > total. > xm top is correct and displays 4GB for Domain-0. > Hm, yes that's expected. Currently some of dom0's memory is hidden behind the PCI aperature and is wasted. The quick fix is to simply return the memory to Xen so that it can at least be properly used; the complex fix is to move that memory higher up the address space so that it's immediately available to dom0. I tried the latter but it turned out pretty complex. The former is relatively simple, and I'll probably apply a patch to do it soonish. Once boot-time ballooning works (ie, starting a domain so that it can be expanded), the memory can be re-added via the balloon driver.
