Virtualization and something more...
1. Installing Recommended Packages
There are few developemnt libraries required to run Ruby on Linux. Use following command to install recommended packages on your server using yum.
# yum install gcc-c++ patch readline readline-devel zlib zlib-devel # yum install libyaml-devel libffi-devel openssl-devel make # yum install bzip2 autoconf automake libtool bison iconv-devel
Today I tried to install knife vsphere support for Chef (You can make it by this command $gem install knife-vsphere ) on Ubuntu and received several errors.
First of them was:
There is new useful utility on VMware Labs for VMware Horizon View administrators which helps them to connect the VMware View Client automatically into a View desktop or an application pool when the system starts up. This can be very useful for thin clients or for turning existing Windows endpoints into thin client systems used to automatically connect into a View desktop.
When I try to install Chef Manage on Centos 7 as described here
$ chef-server-ctl install opscode-manage
If you will receive the following error during vSphere 6.0a –> 6.0b updating:
Today I tried to upgrade my standalone (not in Cluster) host (HP DL 180 G6) with esxi 6.0 and Update Manager. But when the process starts I had received this error:
The upgrade contains the following set of cpnflicting VIBs:
Mellanox_bootbank_net-mlx4-en_1.9.9.0-1OEM.550.0.0.1331820
Few weeks ago VMWare released VSAN Health Check Plugin. This plugin allows monitoring and troubleshooting your VSAN 6.0 Clusters. There are two versions of this plugin: first for Windows based vCenter Server and the second – for Linux VCSA (rpm file). VSAN Health Check plugin allows you to collect information about Cluster and its health, which would otherwise needed to be gathered via RVC or CLI. There is also a vib file which you need to deploy on your esxi hosts in VSAN Cluster. The deployment of the VIB file can be done through vSphere web client (other methods are through RVC, VUM or manually via CLI with “esxcli software vib” commands).
Today I want to install esxi 6.0 to my HP Microserver Gen8, which has only 4Gb of RAM. During the installation you will receive error as on screen below:
The esxi (standalone server) is free, but it must be licensed. If not, it installs as 60 days trial, which expires after 2 month.
1. Download the VMware Hypervisor from this page (you’ll need to create an account if you don’t have one – it’s free). For esxi 5 use this page.
If you receive such message on your virtual machine, you have workaround to fix this problem.
