[Xen-users] XEN Dom 0 boot and Out of Memory issue
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 CenOS (2.6.38.4).
I am not ale to attach the log of the serial console. A snippet from the log
file:

RE: [Xen-users] XEN Dom 0 boot and Out of Memory issue
HI, I disabled the x windows and was able to boot the DOM 0. "dom0_mem=512m" worked fine. At the time of starting I am getting following warning: Starting xenstored...XENBUS: Unable to read cpu state Tanish> Date: Thu, 12 May 2011 21:23:49 -0800 > From: jonr@destar.net > To: xen-users@lists.xensource.com > Subject: Re: [Xen-users] XEN Dom 0 boot and Out of Memory issue > > On 05/12/2011 08:25 PM, Tanish Srivastava wrote: > > > > > > > > > > Hi all, > > > > Recently I build XEN 4.1 (from the xen.org) on centIOS > > 5.5 (kernel 2.6.38.4).
