Problem xen not starting...!!!//I have the same problem.... 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 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.32.57-2.el6xen.x86_64) root (hd0,0) kernel /xen.gz dom0_mem=1024M cpufreq=xen dom0_max_vcpus=1 dom0_vcpus_pin kernel /vmlinuz-2.6.32.57-2.el6xen.x86_64 ro root=/dev/mapper/vg_xen-LogVol01 rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_xen/LogVol01 rd_LVM_LV=vg_xen/lv_swap rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet initrd /initramfs-2.6.32.57-2.el6xen.x86_64.img title CentOS (2.6.32-279.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-279.el6.x86_64 ro root=/dev/mapper/vg_xen-LogVol01 rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_xen/LogVol01 rd_LVM_LV=vg_xen/lv_swap rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet 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.
