Publishing a shortcut to Citrix XenApp

All of us who use Citrix XenApp to publish apps have come across an app that resists being published, either because it has characters that we can't enter in the path, or why it has a somewhat strange command line, This is for example more than two parameters and this is not supported. To solve this type of incident, We can take advantage of the shortcut left by the manufacturer of the application, since in a shortcut (.lnk) it can have any character or all the parameters that such an application has.

Using VMware FT

Another new feature of VMware vSphere 4 is the ability to use Fault Tolerance or FT. It is the ability to have real high availability, This is, with previous versions of VMware, we had DRS, that if a physical host went down, the virtual machines running on it, they run on another host, Foresaw a restart of the virtual machines. What VMware FT gives us is the possibility that virtual machines do not have to be restarted, and in case of ESX host crash with virtual machines, those that are protected with FT will continue to run on another host without loss of service.

Configuring Physical Appliances for Virtual Machines in VMware

One of the new features of VMware vSphere is the ability to give physical devices from hosts to virtual machines, This ensures that the driver of the virtual operating system, Directly access the physical device in question, The advantages of course is the increased performance of the device, as latencies are reduced. Latest version of VMware Tools required, it should also be taken into account that they can only be assigned 2 per virtual machine and 8 Per Host. And logically such a virtual machine will lose all the advantages of moving to other hosts, since we are assigning a physical device of a specific host. This is called VMDirectPath I/O.

Deploying corporate Outlook signatures automatically

An atypical document, but super interesting if we find ourselves in this case. I had the need to put a corporate fund and a corporate signature for my users' email, it doesn't matter Outlook 2003 than with Outlook 2007 or directly with OWA; my servers are Exchange 2003 and Exchange 2007. I needed a tool that would integrate with Active Directory and that could automatically put a signature on each user with their name, Surnames, charge, email… without me manually having to do anything, that takes it all from the Active Directory data. And then deploy it automatically with a GPO directive and vúalá! All users with corporate email.

Using Host Profile in VMware vSphere

One way to help us in the configuration of our virtual environment is to rely on one of the new features that VMware vSphere brings 4, the ability to use already configured templates to apply to all our ESX hosts, or for when we add a new VMware ESX host to our virtual community, we can apply the same configurations that one of our hosts already has.. We can create a template from scratch by configuring everything manually or get said template from one of our servers already configured perfectly (being able to edit the profile if necessary), and then apply it to the rest of the hosts that do not meet the requirements that we indicate. This is called the VMware Host Profile.

Using Veeam Backup & Replication to make backups and replicas of our virtual environment

This Veeam product called Veeam Backup and Replication, offers us the possibility of both backups and replication of our VMware virtual environment, for both VMware Infrastructure 3 How to VMware vSphere 4 (VMware ESX or VMware ESXi, depending on the license purchased, that the product is paid for, but very cheap). It will allow us to make backups of the virtual machines that we indicate in the location that interests us, We will be able to keep as many copies of the same virtual machine as we are interested in, as Veeam will store them incrementally. Personally, what I like is the replication, since the backup is given to us by VCB or VMware Data Recovery, replication can be carried out in another storage array that we have and the replicated virtual machines will be optionally placed in the VMware inventory, just like backups, We can have so many replicas […]

Using VMware Data Recovery to Back Up VMware vSphere

VMware Releases New Virtual Machine Backup System Called VMware Data Recovery. It is a virtual appliance based on CentOs 5.2 which we will incorporate into our virtual environment, and with a plugin we can manage from the VMware client, as it integrates with our VMware vCenter Server. I have to tell you that I love how it works, is fully customizable, We can make backups of the virtual machines that we are interested in, We can indicate how many copies we want it to keep of each virtual machine and for how long; how many machines you keep for us for a specific time. The best thing is the technology you use to make backups called deduplication, This will prevent duplicate copies of virtual machines, but in the next copy it will only copy the differences with the complete copy, This is, an incremental copy! We will be able to restore the entire virtual machine, […]

Migrating VMware VI3 Virtual Network Environment to VMware vSphere with Distributed Switches

Well, once we have our entire virtual environment already migrated to the new version of VMWare vSphere 4.0, all servers running under VMware ESX 4.0 and our VMware vCenter Server as well, We will be able to enjoy its advantages, One of them is the new switch environment, called Distributed Switches or vNetwork Distributed Switches. With this we will achieve comfort when managing network environments, Much simpler, Change the way switches are configured, No more configuring a switch or virtual network for each host, otherwise, is a global environment, everything is done at the vCenter Server level and will apply to all of our hosts.

Anti-disestablishmentarianism

Title should not overflow the content area A few things to check for: Non-breaking text in the title, content, and comments should have no adverse effects on layout or functionality. Check the browser window / tab title. If you are a plugin or widget developer, check that this text does not break anything. The following CSS properties will help you support non-breaking text. -ms-word-wrap: break-word; word-wrap: break-word;
