VMware Data Recovery and damaged restore points

23 February 2012
Comments off

Reading Time: 2 minutesAs written in the VMware Data Recovery (VDR) as a backup solution post, VDR could be a possible backup solution for small environment (if there are big budget constraints). But some issues are really quite difficult to handle with this appliance and the biggest one is the integrity of CIFS NAS destinations. If you cannot avoid them and for some reason you cannot limit them to 0.5 TB for each destination, you may have some integrity check errors (sometimes). Most of them could depend by some damaged restore points, in this case you can view […]

Build a XenServer Pool in a virtual environment

21 February 2012
Comments off

Reading Time: 3 minutesIn the previous post I’ve esplain how to install XenServer 6.0 (but can works also with previous versions) in a VM, using VMware products like Workstation 8 or vSphere 5. To build a XenServer Pool (that is basically the same of a VMware Cluster) you need at least two hosts and a shared storage (and of course a shared network). I suggest to do not clone the second host from the fist because XenServer works with several UUID and in this way you will clone also the host UUID and XenCenter will be not able […]

Install XenServer 6.0 in a VM

20 February 2012
Comments off

Reading Time: 3 minutesAs written in a previous post, Citrix with XenServer 6 is trying to fill the gap from VMware vSphere… and most features (included distributed virtual switches) are now common also in this type of solution. Of course features are only one of the possible criteria to select an hypervisor and a virtualization solution. To make some practice or just to have a look at the product, it is possible run it in a VM on VMware products, both Workstation 8 (and probably also 7) and vSphere 5 can be used.

VCB with vSphere 5 and Windows Server 2008

9 February 2012
Comments off

Reading Time: 2 minutesAs written in the previous post related to the upgrade to vSphere 5, the old VCB framework can still be used also with latest version, but is a not supported configuration (I’ve made the test only with a Windows Server 2008 R2 for the VCB proxy, but I suppose that works also with previous OS). Of course the SAN transport mode could not work (or not if you use VMFS5), but the NBD works as on the old vSphere 4.x. The only issue that I get (but honestly I’ve make only few tests) is on […]

Storage vMotion issue with Symantec Backup Exec

8 February 2012
Comments off

Reading Time: 2 minutesSome days ago I found a strange issue with vSphere 5 where some VMs was not movable with Storage vMotion with a strange error: The method is disabled by ‘SYMC-INCR dd-mm-yyyy hh:mm’. From the name SYMC my first though went on Symantec Backup Exec (the 2010 R3 version) and may on some corrupted snapshots: but the VM file where good, and there was nothing to be consolidate. I’ve looked in the VMware KB and I found the KB 2008957 (Storage vMotion fails with the error: The method is disabled by ‘SYMC-INCR dd-mm-yyyy hh:mm’) with the […]

Using PHD Virtual Monitor with XenServer and vSphere

7 February 2012
Comments off

Reading Time: 4 minutesPHD Virtual Monitor is a comprehensive virtualization monitoring solution that gives you complete visibility across your entire virtual IT infrastructure at all levels including virtual, physical and application. So it not only a multi-hypervisors monitor tool (as described in the previous post), but also a multi-environments tool. This could be really interesting with Citrix XenServer environments where the monitoring feature are quite minimal (and without simple notification in the free edition): CPU and Memory, both for hosts and VMs; and from latest version also networking and disks (but disk only for VMs). Also the graphs […]

Virtualization ecosystem is becoming multi-hypervisor

6 February 2012
Comments off

Reading Time: 3 minutesOne trend in the last year(s) is that the virtualization ecosystem is growing outside the boundary where was born: historical partner vendor of VMware now are extending their solution to other hypervisors, and also also new products are designed to managed a more complex virtual environment. This was also called “Hypervisor Agnosticism” in a VKernel post. We do not talk about interoperability across different hypervisors, but simple use same tools, especially for management, monitoring and data protection, for more type of products. Does it make sense? For a single customer maybe not… have multiple environment […]
