Hi Everyone, I have set dom0_mem=2048M in grub2, set dom0 minimum memory to 2048 in xend-config (and also disabled ballooning). However, when I do "free -m" in the Dom0, I only see 1567 total RAM (xentop reports 2048ish). Is this a known issue? I am also aware that this problem occurs in the DomUs as well, but never a discrepancy that big. The kernel I''m using is 3.2.28. Xen is version 4.1.3 (although I''m using a hack in setup.c where I changed the order of the if block is give priority to the 802 memory map. I needed to do this as my motherboard uses UEFI. Keir made a patch for this for unstable recently). Any help is appreciated. Thanks
