Hello,i want to know if there is any way to install LVM (Logical Volume Management) manually and separately on Linux operating system as when i initially installed RedHat Enterprise Linux 6,i mistakenly did not select the application LVM itself.

Another issue i have not been able to fix is the Virtual Machine Manager.i have tried to connect but it keeps showing me the following error message on RedHat Enterprise Enterprise Linux 6.

Error Message from Virtual Machine Manager :
Unable to open a connection to the libvirt management daemon.
Libvirt URI is: qemu:///system
Verify that The 'libvirtd' daemon has been started


any advices,please feel free to let me know.thank you.

    You can install the tools like this:
    # yum install -y lvm2
    Although you can use the tools to construct new LVM devices and partitoins, you can't change your existing partitions into LVM.

    On your physical host, do this:
    # /sbin/chkconfig libvirtd on
    # /sbin/service libvirtd start
    This will start the virtualization tools.

    TommyReynolds ,Thanks for your reply but i am still getting the same error message everytime i try to connect to Virtual Machine Manager.here is the more detailed error message for your convenience.

    no connection driver available for qemu:///system

    Traceback (most recent call last):
    File "/usr/share/virt-manager/virtManager/connection.py", line 1022, in tryopen
    None], flags)
    File "/usr/lib/python2.6/site-packages/libvirt.py", line 102, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')
    libvirtError: no connection driver available for qemu:///system


    As for LVM,i have applied what you have suggested on terminal but to no avail.it would show me the LVM application under System>Administration tab if it was successfully installed.

    You can install the LVM GUI using:
    # yum install system-config-lvm
    Regarding Virtual Machine Manager... are you trying this as root on the server console?

    Dude,I will let you know the update on LVM when i install it tonight.

    I tried running Virtual Manager as root on RedHat Linux Enterprise 6 on my home PC.it just keeps on promoting the same error message as shown on my previous post.

    any way to fix the issue?

    cheers!
