    Hi,

    I am trying to install OpenVZ in Fedora 9 with the help of "Installing And Using OpenVZ On Fedora 9" published in How to Forge article section.

    Everything went ok except, the system is showing error as
    "Unable to access resume device (/dev/VolGroup00/LogVol01)
    Could not find filesystem '/dev/root' ", while booting and system don't get booted.

    However the system is booting with original kernel.

    Please help me to resolve this problem

    Can you post your /boot/grub/menu.lst and /etc/fstab?

    I'm not sure why it says LogVol01.

    What are the outputs of
    Code:
    pvdisplay
    vgdisplay
    lvdisplay
    ?

    Ok there you have /dev/VolGroup00/LogVol01. What partition do you have on that volume?
    What's the output of
    Code:
    mount
    , and what's in /etc/mtab?

    Similar problem

    I was having a similar problem with the error about the resume device. I resolved this problem by unpacking the initrd file and editing the init file to remove the reference. Instructions for unpacking/repacking the initird are here: http://forums.fedoraforum.org/showthread.php?t=111565

    I also converted all UUID references in /etc/fstab to /dev/sda references.

    I still get the error "could not find filesystem '/dev/root'".

    The grub/menu.lst entry is this:
    title Fedora OpenVZ (2.6.18-92.1.1.el5.028stab057.2)
    root (hd0,0)
    kernel /vmlinuz-2.6.18-92.1.1.el5.028stab057.2 ro root=/dev/sda2 rhgb quiet
    initrd /initrd-2.6.18-92.1.1.el5.028stab057.2.img

    /etc/fstab:
    /dev/sda2 / ext3 defaults 1 1
    /dev/sda5 /home ext3 defaults 1 2
    /dev/sda1 /boot ext3 defaults 1 2

    /etc/mtab:
    /dev/sda2 / ext3 rw 0 0
    proc /proc proc rw 0 0
    sysfs /sys sysfs rw 0 0
    devpts /dev/pts devpts rw,gid=5,mode=620 0 0
    /dev/sda5 /home ext3 rw 0 0
    /dev/sda1 /boot ext3 rw 0 0

    output from mount is similar.
