How to Install VMware Tools to Centos via YUM repository

By Emanuelis, on January 6th, 2012

I used this to install VMware tools to CentOS 6.2 on ESXi 4.1

Add VMware GPG keys:

rpm –import http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-DSA-KEY.pub rpm –import http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-RSA-KEY.pub

Edit /etc/yum.repos.d/vmware-tools.repo:

[vmware-tools] name=VMware Tools baseurl=http://packages.vmware.com/tools/esx/4.1latest/rhel6/$basearch enabled=1 gpgcheck=1

Install VMware Tools:

yum install vmware-open-vm-tools-nox

vCenter should show “Unmanaged” – this means that CentOS package manager is responsible for updates.

By Emanuelis, on June 4th, 2010

I like LXC very much. But this error was killing me for a few days. Google gave me no answer about that.

I have Ubuntu 10.04 Lucid Lynx as a host and as LXC guest. This is what I was getting while trying to ssh to virtual host “hostingas”:
