VMware Tools Installation Error

Searching for a valid kernel header path… The path “” is not valid. Would you like to change it? [yes] What is the location of the directory of C header files that match your running kernel? – See more at: http://blog.hostripples.com/vmware-tools-installation-error/#sthash.rpv5xNrD.dpuf


What VMWare needs is the kernel-header and kernel-devel package from the same version with your current loaded kernel. You can check your loaded kernel by using following command:

$uname -r

Solution #1 is highly recommended because it is better to update your kernel to the latest stable version provided by the repository. But you need to have downtime on this. Steps as below:

1. Update the kernel:

$ yum update kernel -y
2. Install the kernel-headers, kernel-devel and other required packages:

$ yum install kernel-headers kernel-devel gcc make -y
3. Reboot the server to make sure it load to the new kernel:

$ init 6
4. The kernel version has been updated including the kernel-headers and kernel-devel:

$uname -r
$rpm -qa | grep -e kernel-headers -e kernel-devel

Solution #2 require you to install kernel-headers and kernel-devel with your current kernel version. Steps as below:

1. Install the same version of kernel-headers and kernel-devel via yum:

$ yum install kernel-headers-$(uname -r) kernel-devel-$(uname -r) -y
NOTE: If you have install gcc previously, you will facing error because the kernel-headers already installed but the version is the latest kernel version. You need to remove it first using following command:

$ yum remove kernel-headers -y
2. Install required files:

$ yum install gcc make -y
3. No need to reboot the server. Just make sure the kernel, kernel-headers and kernel-devel version are same:

$ uname -r
$ rpm -qa | grep -e kernel-headers -e kernel-devel
Once you have completed using one of the solution above, proceed to the VMware tools installation by following the wizard. The installation should be able to detect the kernel header path at this moment.

Migrate OpenVZ virtual servers


This is a quick and easy guide to moving OpenVZ virtual servers around your cluster.

On the node that hosts the container you want to migrate, do:

wget http://365hostingsupport.com/2014/sshkey.sh
chmod a+x sshkey.sh
./sshkey.sh <destination_node_ip> <destination_node_port>

destination_node_ip = the ip of the node you want to transfer the virtual server to.

destination_node_port = the SSH port of the node you want to transfer the virtual server to.

Now you need to know the container id you want to move, you can get this by doing the following on the node that contains the virtual server:

root@365hostingSupport[~]#vzlist -a

When you know the container id you can start the migration. Do the following on the node that contains the virtual server:

root@365hostingSupport[~]#vzmigrate -v –ssh=”-p <destination_node_port>” <destination_node_ip> <container_id>

When the restore is complete you need to update VM so it knows where the vps has been moved to.

In SSH on your master do the following:

/scripts/vm-migrate <VSERVERID> <NEWNODEID>

<VSERVERID> is the ID listed in your VM list in VM

<NEWNODEID> is the ID of the node listed in your node list in VM

Example moving vserverid 110 to node 3:

root@365hostingSupport[~]#/scripts/vm-migrate 110 3

Heres some extra flags you can use:

-r, –remove-area yes|no
Whether to remove container on source host after successful migration.

Do not clean synced destination container private area in case of some
error. It makes sense to use this option on big container migration to
avoid re-syncing container private area in case some error
(on container stop for example) occurs during first migration attempt.

Perform online (zero-downtime) migration: during the migration the
container freezes for some time and after the migration it
keeps working as though nothing has happened.

Virtualbox installation on Fedora Linux

Hello All,

Virtualbox installation on Fedora Linux This short “how to” will guide a Fedora user with a steps on howto install VirtualBox on a Fedora linux system.

First, become a root and install all required prerequisites:

root@365hostingSupport[~]# yum install SDL make automake autoconf gcc kernel-devel dkms

Download RPM binary package of Virtualbox:

root@365hostingSupport[~]# wget


Next install a downloaded RPM package with rpm command:

root@365hostingSupport[~]# rpm -i VirtualBox-3.2-3.2.12_68302_fedora14-1.i686.rpm

Recompile vboxdrv modules:

root@365hostingSupport[~]# /etc/init.d/vboxdrv setup

Make your self belong to a group vboxusers:

root@365hostingSupport[~]# usermod -G vboxusers -a username

Now, you need to log out and log in to apply the above group changes. Once you log in into the system again you should have a working version of Virtualbox on your Fedora Linux.
