[Xen-devel] domU not reporting more than 1GB of RAM even while xm list is showing 1.5GB.
I am having an issue where domU will not report more than 1GB of memory even while xm list is showing 1.5GB. when starting domU with more than 1GB of RAM it only reports 1GB <using cat /proc/meminfo while in domU>. xm list in dom0 clearly shows the 1.5GB allocated in the config file and by trial and error (manipulating the mem in dom0 I am sure it is at least trying to allocate the 1.5GB). I am on a machine with 2GB of physical RAM and allocating 256MB to dom0. Am I hitting some type of limitation here (xen 2.0.1 on FC3) I am attaching the output from xm list and <cat /proc/meminfo> Dom0: xm list Name Id Mem(MB) CPU State Time(s) Console Domain-0 0 245 0 r---- 1202.9 xm6 10 1535 1 -b--- 3.8 9610 DomU : cat /proc/meminfo MemTotal: 904880 kB MemFree: 865352 kB Buffers: 3468 kB Cached: 22600 kB SwapCached: 0 kB Active: 17796 kB Inactive: 13292 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 904880 kB LowFree: 865352 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB Mapped: 10780 kB Slab: 5580 kB Committed_AS: 21544 kB PageTables: 452 kB VmallocTotal: 57312 kB VmallocUsed: 52 kB VmallocChunk: 57260 kB Jessie --------------------------------- Do you Yahoo!?

Are you using the default xenU? I believe you will find it built with HIGH MEMORY SUPPORT set to off when you want it set to 4Gb. B.
