Hi,

I followed tutorial http://www.howtoforge.com/virtualization-with-xen-on-centos-6.2-x86_64-paravirtualization-and-hardware-virtualization

To install xen on Centos 6.3 everything is going perfect but, after editing /boot/grub/menu.lst 

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/mapper/vg_xen-LogVol01
# initrd /initrd-[generic-]version.img
#boot=/dev/sdb
default=0
timeout=5

initrd /initramfs-2.6.32-279.el6.x86_64.img


when i reboot it is booted with xen kernel but when i run command

xm info or xm list

showing error " Error: Unable to connect to xend: No such file or diectory. Is xend running "

when i run command

xend start

showing error

" xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
xend/image.py: Error connecting to hypervisor "

ls /proc/xen

" ls: cannot access /proc/xen: No such file or directory "

added entry in /etc/fstab

none /proc/xen xenfs default 0 0

after reboot gives error no such file or directory,

lsmod | grep -i xen output: Nothing...

modprob xen-evtchn

FATAL: Error inserting xen_evtchn (/lib/modules/2.6.32.57-2.el6xen.x86_64/kernel/drivers/xen/xen-evtchn.ko): No such device

modprob xen-gntdev

FATAL: Error inserting xen_gntdev (/lib/modules/2.6.32.57-2.el6xen.x86_64/kernel/drivers/xen/xen-gntdev.ko): No such device

I tried another tutorial https://www.crc.id.au/xen-on-rhel6-scientific-linux-6-centos-6-howto/

it seems like nothing is working for me...

Guys... please share your thoughts about this problem...

Thank you.
