How to create new Local SR in XenServer

In this blog, I will explain the process of creating an additional local SR in XenServer. In this scenario, there is an additional hard disk present in the server which I plan to add as a local SR in addition to the existing Local storage

First you need to identify which disk is being currently used for your existing local SR, so that it is not accidentally deleted

1)SSH to your server using putty

type the command xsconsole

In the console that is displayed go to Disks & Storage repositories -> Current Storage Repositories

You need to locate your current local repository and view the properties on the right pane









Note down the scsi ID

2)Type the following command

#ll /dev/disk/by-id

Note down which device the ID maps to. In this case it is sda3.So that is your present local SR







Also you need to note the SCSI id of the disk that you are planning to use for the new SR. In my case it is sdb




3)Next step is to create the new SR. You need run the following command and note down the "uuid"

#xe host-list

4) Create new SR using the following command


# xe sr-create content-type=user device-config:device=/dev/disk/by-id/<scsi-xxxxxxxxxxxxxxxxxxxxxxxxx> host-uuid=<host-uuid> name-label=”Local Storage 2” shared=false type=lvm

you need to replace the scsi id and host uuid

Now you should be able to view the new Local SR in the XenCenter!!

Install nested KVM in VMware ESXi 5.1

In this blog, I will explain the steps required to run a nested KVM hypervisor on  Vmware ESXi. The installation of KVM is done on Ubuntu 13.10(64 bit). Note: It is assumed that you have already installed your Ubuntu 13.10 VM in ESXi, and hence we will not look into the Ubuntu installation part. 1) Upgrade VM Hardware version to 9. In my ESXi server, the default VM hardware version was 8. So I had to shutdown my VM and upgrade the Hardware version to 9 to get the KVM hypervisor working. You can right click the VM and select the Upgrade hardware option to do this. 2)In the ESXi host In /etc/vmware edit the 'config' file and add the following setting vhv.enable = "TRUE" 3)Edit the VM settings and go to VM settings > Options  > CPU/MMU Virtualization . Select the Intel EPT option 4) Go to Options->CPUID mask> Advanced-> Level 1, add the following CPU mask level ECX  ---- ---- ---- ---- ---- ---- --H- ---- 5) Open the vmx...

Virtual fibre channel in Hyper V

Virtual fibre channel option in Hyper V allows the connection to pass through from physical  fibre channel HBA to virtual fibre channel HBA, and still have the flexibilities like live migration. Pre-requisites: VM should be running Windows Server 2008, 2008 R2 or Windows Server 2012 Supported physical HBA with N_Port Virtualization(NPIV) enabled in the HBA. This can be enabled using any management utility provided by the SAN manufacturer. If you need to enable live migration, each host should be having two physical HBAs and each HBA should have two World Wide Names(WWN). WWN is used to established connectivity to FC storage.When you perform migration, the second node can use the second WWN to connect to the storage and then the first node can release its connection. Thereby the storage connectivity is maintained during live migration Configuring virtual fibre channel is a two step process Step 1: Create a Virtual SAN in the Hyper-V host First you need to click on Vir...

The Cloud Migration Gotchas..

All leading cloud providers have a well defined Cloud Adoption Framework that will help you shape up your cloud migration strategy. Customers would eventually end up with one of the 5 'R's of rationalization - Rehost(Lift&shift) , Refactor, Rearchitect, Rebuild or Replace.  Once you have identified the approach , next steps would be planning and execution. However the best  plans laid out by  a professional services team can be driven off the track by  customer specific environment challenges. If you are helping customers with cloud migration, here are few things that you might want to think through again and prepare for before you go all in . 1.Start with stakeholder buy in The first step called out in Azure Cloud Adoption Framework is Strategy  or rather the motivation of the organization to move to cloud. Though this would usually be done in the presales phase and might have the buy in of the C-Suite, it is very important that this acceptance trickles do...
