centos5/xen does not see all memory
...meone advice me how to get it recognize all my memory?
I have installed 32bit CentOS5 and I'm running
kernel-xen-2.6.18-8.1.8.el5. This kernel should have PAE support:
$ grep PAE /boot/config-2.6.18-8.1.8.el5xen
CONFIG_X86_PAE=y
But xentop reports only 3 gigs of memory:
Mem: 3145148k total, 2400512k used, 744636k free CPUs: 2 @ 2612MHz
If I boot with kernel-PAE-2.6.18-8.1.8.el5 the system recognizes all
memory but I cannot use Xen.
My motherboard is Supermicro H8SMA-2 A64/Opteron with MD Athlon 64 X2
5200+ processor
and 2 x 1GB ECC DDR-II SDRAM and 2x 2GB ECC DDR-II SDRAM.
Regards,
Peter
