This procedure, adding physical block devices to virtualized guests, describes how to add a hard drive on the host to a virtualized guest using VMWare software running Linux as guest.

It is possible to add or remove a SCSI device explicitly, or to re-scan an entire SCSI bus without rebooting a running Linux VM guest. This how to is tested under Vmware Server and Vmware Workstation v6.0 (but should work with older version too). All instructions are tested on RHEL, Fedora, CentOS and Ubuntu Linux guest / hosts operating systems. ]]> http://www.cyberciti.biz/tips/vmware-add-a-new-hard-disk-without-rebooting-guest.html/feed 18 http://www.cyberciti.biz/tips/howto-resize-vmware-virtual-harddisk-size.html http://www.cyberciti.biz/tips/howto-resize-vmware-virtual-harddisk-size.html#comments Tue, 09 Jun 2009 14:22:42 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=4998 I've Windows Vista installed as a guest under Ubuntu Linux using VMWARE Workstation 6.0. This is done for testing purpose and browsing a few site that only works with Internet Explorer. Since I only use it for testing I made 16GB for Vista and 5GB for CentOS and 5GB in size for FreeBSD guest operating systems. However, after some time I realized I'm running out of disk space under both CentOS and Vista. Adding a second hard drive under CentOS solved my problem as LVM was already in use. Unfortunately, I needed to double 32GB space without creating a new D: drive under Windows Vista.

My test server runs inside VMWare server version 2.0. It was working fine with my Laptop.

You may wonder computers are getting cheaper every day, why should I care and why should I use virtualization? Virtualization is a broad term that refers to the abstraction of computer resources such as:

1. Platform Virtualization
2. Resource Virtualization
3. Storage Virtualization
4. Network Virtualization
5. Desktop Virtualization

This article describes why you need virtualization and list commonly used FOSS and proprietary Linux virtualization software. ]]> http://www.cyberciti.biz/tips/linux-virtualization-software.html/feed 20 http://www.cyberciti.biz/tips/start-stop-vmware-virtualization-vms-command.html http://www.cyberciti.biz/tips/start-stop-vmware-virtualization-vms-command.html#comments Wed, 29 Oct 2008 07:02:41 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=3235 You can easily start / stop / pause or take a snapshot from a shell prompt under a Linux / Windows host using vmrun command.
