How to Create and Install Guest Virtual Machines in Xen. Server. Continuing to move forward with the Xen. Server series, this article will approach the creation of the actual guests themselves (often called virtual machines). Update: In May 2. Citrix released the new version of the Xen. Server 7 platform. For installation follow: Fresh Installation of Xen. Server 7. Create and Install Guest Virtual Machines in Xen. Server. This article will assume all the previous articles covering networking, patching, and storage have been completed. Thankfully, no more new terminology really needs to be discussed and the creation of the guests can begin! System Review. At this point, a lot has been configured on this Xen. Server host. This will serve as a quick review about what has been configured and which article the topic was discussed. Xen. Server 6. 5 was installed to the serverhttps: //www. All Xen. Server 6. Network interface teaming and VLANs were createdhttps: //www. SCSI and ISO storage repositories were created to hold operating system installation files and the virtual harddisks used by the guestshttps: //www. Creation of Virtual Guests in Xen. Server. This portion of the guide will be relying on ISO installers to actually boot the newly created guest machine and install an operating system. Be sure to review the fourth article for information on creating an ISO repository. ![]()
Xen. Server comes with a series of templates that can be used to quickly provision a virtual guest. These templates provide common options for the chosen operating system. Options include things such as hard drive space, CPU architecture, and amount of ram available among other options. Hi thanks for you work writing this up. I went through the installation steps using the Debian Wheezy build after upgrading but I have a problem. rtl_test detects the. Dans ce tutoriel nous allons mettre en place un serveur de VOIP Asterisk sur un serveur linux Debian ou Ubuntu et passer un premier appel entre deux utilisateurs. These options can be manually modified later but for now a simple template will be used to illustrate their usage. To obtain the list of available templates, the traditional 'xe' command can be passed different arguments to prompt the system to return the templates available.# xe template- list. This command is likely to return a lot of output. To make the output easier to read, it is suggested that the output be piped into ‘less’ as follows: # xe template- list | less. This will allow for easier parsing of the available templates to locate the necessary UUID information. This article is going to be working with Debian 8 Jessie but will require the use of the older Debian 7 Wheezy template until Citrix releases the new template. Selecting Debian 7 won’t affect anything in the operation of the actual operating system. The screen shot below used the UUID in the command to trim out some of the normal output). Check Xen. Server Template List# xe sr- list name- label=”Tecmint i. SCSI Storage”. List Xen. Server Storage Label Name. With this UUID, all of the initial information to setup this guest has been obtained. As with almost everything in Xen. Server, another ‘xe’ command will be used to provision the new guest.# xe vm- install template=”Debian Wheezy 7. Tecmint. VM" sr- uuid=bea. Xen. Server Guest Template Creation. The highlighted UUID is the UUID of the newly provisioned guest. There are a couple of house keeping steps that can potentially make things easier in the future. The first is to provide a name- label to the newly created VDI and the second is modifying any of the default hardware specifications provisioned by the template. To see why it would be important to name the VDI, take a look at what the system will automatically assign to the VDI when provisioned using the following ‘xe’ commands: # xe vbd- list vm- name- label=Tecmint. VM – Used to get the VDI UUID. Used to show naming issue]. Check Xen. Server VDI Name and UUIDAnother option available is to gather both pieces of information is the following command: # xe vm- disk- list vm=Tecmint. VM. List Virtual Machine Disk Information. The part in yellow is the concern. To many people this issue is minor but for house keeping purposes a more descriptive name is desired to keep track of the purpose of this particular VDI. To rename this particular VDI, the UUID in the above output is needed and another ‘xe’ command needs to be created.# xe vdi- param- set uuid=9. Tecmint. VM Disk 0 VDI". Tecmint. VM. Rename VDI Name Label. This may seem trivial to set but from experience, this has prevented a serious issue when detaching a storage repository from one Xen. Server and attempting to attach it to another Xen. Server. This particular scenario, a metadata backup of all the guest information failed to be restore- able on the new Xen. Server and thankfully by naming the VDI on each of the guests, proper mapping of the guest to its VDI was able to be done simply by the name- label. The next house keeping step for this article is to provide this particular guest with more resources. As provisioned this guest will only have about 2. Mi. B (Mebibytes) worth of memory. Most guests this isn’t enough so it is beneficial to know how to increase a guest’s available memory. As with anything in Xen. Server this can be accomplished with ‘xe’ commands.# xe vm- param- list uuid=6eab. Check Xen. Server Guest Memory List. The box in green above indicates that the most memory that this particular guest could ever have is about 2. Mi. B. For testing purposes this would be okay but for any sort of heavy use system, this would prove to be insufficient. To modify this value to give the guest access to more RAM, a simple ‘xe’ command can be issued with the guest powered off. In this example, the amount of ram to be given to this machine will be represented in bytes but will equal 2 Gibibytes worth of ram.# xe vm- memory- limits- set dynamic- max=2. Tecmint. VM. Notice that this will reserve two Gi. B of ram for this guest all the time. Increase Xen. Server Guest Memory Limit. Now this particular guest is ready to have an operating system installed. From the previous article about Storage Repositories, a Samba share was added to this Xen. Server to store ISO installer files. This can be confirmed with the following ‘xe’ command: # xe sr- list name- label=Remote\ ISO\ Library\ on: \ //< servername> /ISO. List Xen. Server Samba Share Directory. Be sure to replace < servername> with the name of the proper Samba server for the environment in which this configuration is taking place. Once the Xen. Server is confirmed to see the ISO storage repository, a virtual CD- ROM needs to be added to the guest in order to boot the ISO file. This guide will assume that the Debian Net Installer ISO exists on the ISO storage repository.# xe cd- list | grep debian. Check Guest ISO in Xen. Server ISO Storage# xe vm- cd- add vm=Tecmint. VM cd- name=debian- 8- netinst. Tecmint. VM userdevice=3. Add Guest ISO to Xen. Server. The above commands first list out the name for the Debian ISO. The next command will add a virtual CD- ROM device to the Tecmint. VM guest and assigns it the device ID of 3. The third command is used to determine the UUID for the newly added CD- ROM to continue setting up the device to boot the Debian ISO. The next step is to make the CD- ROM bootable as well as instruct the guest to install an operating system from the CD- ROM.# xe vbd- param- set uuid=3. The first command above sets the CD- ROM to be bootable by using its UUID highlighted in green in the above screen- shot. The second command instructs the guest to use the CD- ROM as the method for installing the operating system. The UUID for the Tecmint guest is highlight in the above screen- shot in yellow. Install Guest Operating System in Xen. Server. The last step in setting up the guest is to attach a virtual network interface (VIF). This is especially important for this install method since the Debian Network installer is being used and will need to pull packages from the Debian repositories. Looking back at the Xen. Server networking article, a special VLAN was already created for this guest and it was VLAN 1. Using ‘xe’ the necessary network interface can be created and assigned to this guest.# xe network- list name- description="Tecmint test VLAN 1. The first command is used to obtain the UUID of the network created for this guest. The next command is used to create a network adapter for the guest and attach the network adapter to the proper network. Add Network Adapter to Xen. Server Guest OSCongrats! At this point, the virtual machine is ready to boot and install! To start the guest, issue the following ‘xe’ command.# xe vm- start name- label=Tecmint. VM. If the terminal doesn’t produce any errors, then the guest started successfully. Install 'Php. Virtual. Box' to Manage Virtual. Box Virtual Machines via Web Browser in Linux. Virtualization is one of the most discussed topic in the field of Linux and IT in general. In the list of 1. HOT IT Skills in demand Virtualization (Vmware) stands at the top of the list. We will be taking you to a quick note of what virtualization is, several virtualization tools before a complete guide on downloading, installing and configuring Virtualbox and Php. Virtual. Box which is a web based virtual box front end. The download, installation and configuration of Virtualbox and Php. Virtual. Box will follow for Debian and Cent. OS based Distributions. What is Virtualization. Virtualization is the process of creating non- real (virtual) version of operating system, storage, network resource and hardware. Virtualization is achieved by creating virtual machines which powers an Operating System. A host physical server can host one or more virtual machine, which may power different OS (Windows, Linux, UNIX, BSD). There are several virtualization tools available. A few of them are platform specific and rest of them are available to be use on any platform. Microsoft Virtual Server 2. R2 – available for x. Support: Windows only. Q – open source virtualization tool available for windows, mac and Linux. Vmware – Available for Windows and Linux. Virtual.
