    Need help with Virtualizor

    Hello,

    I just finished to install Virtualizor but when i login in my admin area, i receive the message "You have booted into the wrong kernel - 2.6.18-274.18.1.el5 .Please reboot into the correct kernel.". What i can do for resolve this problem ? I have tried to reboot the server but without success.

    Also, when i try to create a vps, i see "MB (0 MB Free) " but if i visit the menu "RAM'" i can see my ram:

    Total RAM : 24097 MB
    Utilised : 143 MB
    Utilization % : 0.59 %

    Please help.

    Many thanks!

    NOTE: We are ready to pay if someone helps us solve our problems.

    just check on your grub config @ /boot/grub/menu.lst and see the "default =" line is correct (pointing to your Xen kernel)

    My grub file:

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You do not have a /boot partition. This means that
    # all kernel and initrd paths are relative to /, eg.
    # root (hd0,0)
    # kernel /boot/vmlinuz-version ro root=/dev/sda1
    # initrd /boot/initrd-version.img
    #boot=/dev/sda
    default=0
    timeout=5

    change that to 1, and also that should fix your memory problem.

    short explanation :
    title CentOS (2.6.18-274.18.1.el5) ## default = 0
    root (hd0,0)
    kernel /boot/vmlinuz-2.6.18-274.18.1.el5 ro root=LABEL=/
    initrd /boot/initrd-2.6.18-274.18.1.el5.img
    title CentOS (2.6.18-274.18.1.el5xen) ## default = 1
    root (hd0,0)
    kernel /boot/xen.gz-2.6.18-194.26.1.el5 dom0_mem=512M ## this is for limiting/disable dom0 memory ballooning
    module /boot/vmlinuz-2.6.18-274.18.1.el5xen ro root=LABEL=/
    module /boot/initrd-2.6.18-274.18.1.el5xen.img
    title CentOS (2.6.18-274.el5) ## default = 2
    root (hd0,0)
    kernel /boot/vmlinuz-2.6.18-274.el5 ro root=LABEL=/
    initrd /boot/initrd-2.6.18-274.el5.img

    Well okay thanks for the explanation. I have do the update as your request but now my server refuse to boot.

    My new grub file:

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You do not have a /boot partition. This means that
    # all kernel and initrd paths are relative to /, eg.
    # root (hd0,0)
    # kernel /boot/vmlinuz-version ro root=/dev/sda1
    # initrd /boot/initrd-version.img
    #boot=/dev/sda
    default=1
    timeout=5
    splashimage=(hd0,0)/boot/grub/splash.xpm.gz
    hiddenmenu
    title CentOS (2.6.18-274.18.1.el5)
    root (hd0,0)
    kernel /boot/vmlinuz-2.6.18-274.18.1.el5 ro root=LABEL=/
    initrd /boot/initrd-2.6.18-274.18.1.el5.img
    title CentOS (2.6.18-274.18.1.el5xen)
    root (hd0,0)
    kernel /boot/xen.gz-2.6.18-194.26.1.el5 dom0_mem=512M
    module /boot/vmlinuz-2.6.18-274.18.1.el5xen ro root=LABEL=/
    module /boot/initrd-2.6.18-274.18.1.el5xen.img
    title CentOS (2.6.18-274.el5)
    root (hd0,0)
    kernel /boot/vmlinuz-2.6.18-274.el5 ro root=LABEL=/
    initrd /boot/initrd-2.6.18-274.el5.img

    ah, i didn't noticed it from the first time.. sorry.

    kernel /boot/xen.gz-2.6.18-194.26.1.el5 dom0_mem=512M
    module /boot/vmlinuz-2.6.18-274.18.1.el5xen ro root=LABEL=/
    module /boot/initrd-2.6.18-274.18.1.el5xen.img
    you don't have to. just ask to your provider and explain the situation. or if you have Ipmi kvm just fix it from rescue mode.

    I have open a ticket already.. but i'm not sure to see what is wrong in my grub file ?

    What you write is exactly what is it active in my grub file no ?
