I just installed SuSE11 with kernel 2.6.25.18.0.2-xen PAE on a 16 core 64GB equipped Caneland machine. After booting dom0, top shows that roughly 50GB are missing.

32-bit Xen only supports 16GB. You need to use a 64-bit hypervisor to use more (this will work fine with your PAE dom0 kernel!). -- Keir On 21/11/08 08:44, "abc" <abc@mailbarrier.de> wrote:> I just installed SuSE11 with kernel 2.6.25.18.0.2-xen PAE on a 16 core > 64GB equipped Caneland machine. > After booting dom0, top shows that roughly 50GB are missing. > > Where did all the memory go? > >> top > > top - 09:39:29 up 3 days, 19:37, 6 users, load average: 0.20, 0.25, 0.17 > Tasks: 362 total, 1 running, 360 sleeping, 1 stopped, 0 zombie > Cpu0 : 2.0%us, 0.0%sy, 0.0%ni, 96.7%id, 1.3%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu1 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu2 : 7.6%us, 1.3%sy, 0.0%ni, 91.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu3 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu4 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu5 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu6 : 0.7%us, 0.0%sy, 0.0%ni, 99.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu7 : 1.6%us, 0.0%sy, 0.0%ni, 98.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu8 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu9 : 0.3%us, 0.3%sy, 0.0%ni, 99.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu10 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu11 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu12 : 1.6%us, 0.0%sy, 0.0%ni, 98.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu13 : 2.6%us, 0.7%sy, 0.0%ni, 96.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Cpu14 : 1.7%us, 0.7%sy, 0.0%ni, 97.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.3%st > Cpu15 : 0.3%us, 0.0%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st > Mem: 12968960k total, 12815264k used, 153696k free, 152472k buffers > Swap: 0k total, 0k used, 0k free, 11656392k cached > > > > -- > Gregor > > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
