Hi All,

I have an update on the issue. I think Xen is not able to detect hard-drive as I was able to see some messages that said "Total swap = 0KB Free swap = 0KB" at the boot time.

Following are the /etc/fstab file contents on my system:

# /etc/fstab: static file system information.
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# / was on /dev/sda1 during installation
UUID=7a573a8c-0846-4404-8b40-a5f0256968ea /               ext3    relatime,errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=e53d468a-1263-4e4c-919c-40aeb9838fb4 none            swap    sw              0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0


I also get some messages at the boot time that said something like :

starting udev version 141
deprecated sysfs layout; configure as CONFIG_SYSFS_DEPRECATED.

udevd[2073] inotify_add_watch(3, (null), 10) failed: Bad address.

So, can any one of you please help me with this? I am new in using Xen as such. Hence, I am not getting what is going wrong. But I need to fix this urgently.

Any help is appreciated.

Thanks in advance!

Do let me know if you need more information.

Hi All,

I am getting following error when I try to boot Xen:

"out of memory: kill process 2 (migration/0) score 0 and childeren"

I get this several times and machine hangs eventually.

Here is relevant entry in boot/grub/menu.lst on Ubuntu 9.04:

title       Xen 3.4.2 / Ubuntu 9.04, kernel
uuid        7a573a8c-0846-4404-8b40-a5f0256968ea
kernel      /boot/xen-3.4.2.gz
module      /boot/vmlinuz- root=UUID=7a573a8c-0846-4404-8b40-a5f0256968ea ro console=tty0
module      /boot/initrd-

Has anyone experienced this before? Do let me know. I tried searching in mail-archives but I didn't get anything relevant.

Thanks in advance!
