		<description><![CDATA[Hyper-V Manager error when trying to start my 4th virtual machine: An error occurred while attempting to change the state of virtual machine. Unable to allocate MB of RAM. Insufficient system resources exist to complete the requested service. etc&#8230;   Before I reinstall my test Dell PowerEdge 2900 Quad core server I wanted to share this with you. Hyper-V does not support memory overcommitment and I don&#8217;t like that. The virtual host has 8GB or RAM and I want to run more VMs than just 6 of those; the OS uses almost 1GB and less than 7GB is available for VMs. Some weeks ago I read about  memory overcommitment feature which is available for VMWare&#8217;s ESX/ESXi servers. What is Memory Overcommitment? Memory overcommitment is not a feature in itself, but a collection of technologies out of which “transparent page sharing” is the most interesting in my opinion. The usefulness of transparent page sharing will spring to mind immediately if you consider VDI environments. There, host machines typically run large numbers of identical client operating systems with the same applications installed on them. Since all the clients/guests run the same application set, most of the code pages they need to keep in memory are identical. Each guest keeps separate copies of all system and application EXEs and DLLs in memory &#8211; what a waste! Now consider the following: in memory program code is organized in units of pages. If you had a component that identified all those identical pages in each ...]]></description>

		<description><![CDATA[Last week I run into free disk space problem on my Windows Server 2003 virtual machine and today on another virtual machine running Windows Server 2008 I encountered same thing again. The virtual disk was sized for 10GB and only 80MB was free. The virtual machine is running Windows Server 2008 and Microsoft enhanced the feature for extending basic disk volumes on the fly. In my previous post I needed to add the virtual disk to another server; assign a drive letter and than run the extend option in diskpart. Within VI client extend the &#34;Hard Disk&#34; in the properties of the virtual machine to desired and planned size and goto Computer Management / Storage / Disk Management, right-click and Refresh. &#160; The additional defined disk space will be shown as &#34;Unallocated&#34;. Right-click on the C:\ volume and choose &#34;Extend Volume&#34;. Follow the wizard and within seconds the basic volume has been extended. Thanks to VMWare ESX and Microsoft Server 2008 our lives as System Engineers is becoming easier. As lesson learned size your virtual environment appropriate and especially the Hard Disk configuration. &#160; Related links: Technet &#8211; Extend a Basic Volume]]></description>

		<description><![CDATA[Recently I was working to move a virtual machine test network to production. Before bringing this virtual machine into production I wanted to run the latest updates and during that process my virtual hard disk become full. When I created this virtual machine I configured the initial disk space 6GB. VMWare ESX allows you to extend the virtual disk size on a running virtual machine. How to extend the virtual disk size? Right click on the virtual machine in the VI cleint; choose settings and go to &#8220;Hard Disk 1&#8243; and type new disk size. Click OK. Example of my new Disk Configuration in &#8220;Disk Management&#8221;. To extend the virtual disk we need to go to diskpart and extend the volume. I opened command prompt and opened diskpart; selected the volume and run extend. My virtual hard disk was full and I was not able to extend my basic disk with the additional 2GB. I found the following two solutions how to extend the hard disk. Solution 1 Thanks to Kalpesh Prajapati post I was able to find a solution to my problem. Follow these steps to extend your virtual machine basic hard disk: Shutdown the virtual machine Extend the virtual disk size Add the harddisk to another virtual machine and start it up (second virtual machine) Open command prompt and start diskpart.exe list volumes and select the volume with the disk problem extend the disk Make sure the volume has a drive letter assigned otherwise same warning will be ...]]></description>

		<description><![CDATA[There are couple command line tools that VMWare ESX offers when the server has been installed with the &#8220;Service Console&#8221; mode (without i). In the following example I will explain and show how to create new vSwitch; link a physical network interface and assign a IP address for your &#8220;Service Console&#8221; management interface. [root@LAB-ESX-01 root]# esxcfg-vswitch -a vSwitch0 &#8211;&#62; This will create new virtual switch [root@LAB-ESX-01 root]# esxcfg-vswitch -L vmnic0 vSwitch0 &#8211;&#62; This will link my first physical network interface to vSwitch0 Result of the two commands: As you can see vmnic0 with 1000Mbps has been associated with vSwitch0. Now I would like to have a &#8220;Service Console&#8221; port group sitting on this virtual switch. [root@LAB-ESX-01 root]# esxcfg-vswitch -A Service\ Console vSwitch0 &#8211;&#62; This will create new port group named Service Console. Creating new port group on a virtual switch is nothing more than assigning or defining a interface on a switch. Now I would like to assign a L3 IP address on this interface/portgroup. [root@LAB-ESX-01 root]# esxcfg-vswif -a vswif2 -p &#8220;Service Console&#8221; -i 192.168.1.2 -n 255.255.255.0 -b 192.168.1.255 &#8211;&#62; This will create new L3 interface which is linked to the Service Console port group with an static IP address. ESX server will generate new L2 mac address and assign this to the vswif2 interface. [2008-09-12 13:22:21 'Vnic' warning] Generated New MAC address, 00:50:56:40:49:f4 for vswif2 Target result: Just using two built-in esx configuration command line tools I was able to create and assign new service console ip address on ...]]></description>

		<description><![CDATA[After installing VMWare ESX 3.5 hypervisor host server I would like to manage this system with SSH remotely. Server is manufactured by Dell and the DRAC mgmt card interface is available but I prefer to use SSH. SSH is enabled by default but disallows access for root. See my work log and screenshots how to enable this feature: Login with root from the console Change directory with &#8220;cd /etc/ssh&#8221; Open sshd_config with &#8220;vi sshd_config&#8221; Locate Authentication section and change &#8220;PermitRootLogin no&#8221; to &#8220;PermitRootLogin yes&#8221;; for going into edit mode type i; press ESC to exit Type &#8220;:wq!&#8221; to save and exit the file Restart the SSH deamon with &#8220;service sshd restart&#8221; Start putty.exe or any of you favorite SSH remote management tools to connect to your ESX 3.5 server. This procedure also applies to version 3.x. With this procedure I achieved to manage my ESX server remotely so I don&#8217;t need to use my remote management access card. SSH daemon also support secure file copy protocol which can be used to connect with WinSCP and download or upload any file/virtual machine to your VMFS file system. Please be aware of any security implications! I enabled this kind of access because the management interface is sitting in a different VLAN than the vSwitch networks within virtual machine which are trunked amongst different networks.]]></description>

		<description><![CDATA[Who could ever believe and see VMWare releasing their ESX for free. Last night I read small post on my Windows Mobile device. What is VMware ESXi 3.5? VMware ESXi 3.5 is the industry’s first, thin hypervisor integrated into server hardware. With its next-generation architecture embedded in hardware, VMware ESXi enables a plug-and-play data center with greater security, reliability and manageability. Requiring no installation and minimal configuration, VMware ESXi accelerates server deployment—IT organizations can take servers from boot-up to running production applications in virtual machines in minutes. List of features is amazing and now we all get them for free. Check the full list here, but these are which I like: Bare-metal architecture Small Footprint with only 32MB Virtualization for storage and support for iSCSI VLAN tagging support Wake-on LAN 64bit support Basically all features I missed with VMWare Server and now getting them for free with ESX3i version. Why is VMware making ESXi free? VMware is making its standalone ESXi hypervisor available at no cost in order to help companies of all sizes experience the benefits of virtualization. Customers have shown tremendous interest in ESXi due to its innovative architecture, simple setup, and high performance. Allowing IT administrators to obtain VMware ESXi for free enables everyone to gain access to VMware&#8217;s datacenter technology and prove its value in their own companies. I have nothing more to add than just go download the VMware ESXi data sheet for more information and get a free copy of VMware ESXi and try ...]]></description>

I will post another post with exact error messages, but we were not able to get into the service console nor did the other two boot options work. At some&#160; point he asked me did I have a Linux Live-CD? I was think ooh Yeah going back to old school and grabbed my case and found a BackTrack2 cd from two years ago. After the reboot&#160; and boot into BackTrack we went trough couple of system settings and logs and he asked hey can you forward me the esxcfg-boot.log to me&#160; by email&#8230;. I was using the DRAC console and copy and paste is not going to work ;-(.&#160; Guys from past remember the real tricks when we did those back than with IIS and within couple minutes I was able to get the orginal file to one of my tftpd daemon on the network. How did I get the log files? Download, burn the iso and boot from CD-rom Login with root/toor I prefer the GUI and start KDE by running startx Open Console session ifconfig eth0 up dhcpcd eth0 check you ip address with ifconfig eth0 now run tftp open ip address put esxcfg-boot.log or any other. That&#8217;s all. For more information and download go to http://www.remote-exploit.org/.]]></description>
