Hi all,

Recently I build XEN 4.1 (from the xen.org) on centIOS 5.5 (kernel 2.6.38.4). After changing the grub file and rebooting the machine, I am continuously getting out of memory error. The content of my grub file:

default=0
timeout=5
serial --unit=0 --speed=115200
terminal --timeout=10 console serial
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.38.4)
        root (hd0,0)
        kernel /vmlinuz-2.6.38.4 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
        initrd /initrd-2.6.38.4.img
title CentOS (2.6.38-xen0)
        root (hd0,0)
        kernel /xen-4.1.0.gz loglvl=all dom0_mem=512m guest_loglvl=all  vga=ask,keep apic_verbosity=debug,verbose rhgb
        module /vmlinuz-2.6.38.4 ro root=/dev/VolGroup00/LogVol00 earlyprintk=xen console=ttyS0 nomodeset
        module /initrd-2.6.38.4.img

The machine boots normally in Cen OS (2.6.38.4).
I am not ale to attach the log of the serial console. A snippet from the log file:
