I needed to add more storage space on the /home directory of a Xen guest running on a RHEL5 system. I investigated extending its LUN on the NetApp Filer and then tried running pvresize to see if the Xen guest would recognise the new size. No luck. In the end, i created another iSCSI LUN, mapped it to the Xen host, configured the Xen guest to see the new LUN and let LVM know it had another physical disk to play with. This is how i did it.
If you talk to CIOs who really “get” virtualization, the benefit that excites them the most is not cost savings but agility. I’m talking about the ability to say yes, quickly, to a business side request. Virtualization is helping smart IT leaders morph from “no” people to “yes” people. That’s a huge shift for many IT organizations and companies. But in order to be a yes person, you need to have enough carefully-managed virtual infrastructure on hand.
Michael Rose, Research Analyst at IDC, discusses the rise of best practices for virtual desktop infrastructures in this executive interview sponsored by Citrix Systems.
Citrix have recently announced ‘The Citrix Delivery System’, in under a year Citrix have evolved from the market leader in application delivery with Citrix Presentation server and its supporting products to a full on data center delivery company with Citrix Xen Server, Xen Desktop, XenApp and Provisioning Server.It is going to be a busy I think.
