Oracle Enterprise Linux on HyperV

One of the major limitation  I am having now is the VMs with non supported gust OS. Some of the tweaks which is found on the net works but however, not confident to try it out on production machines. With Windows Server 2012 R2, I see that Hyper-V will be improving its support specific to Linux VMs.

Yesterday, Microsoft and Oracle made announcements their joint partnership.

Customers should expect all Oracle products will be supported on Hyper-V as well as Azure soon.

Cheers !



Windows Server 2012 R2 and Network Virtualization

Seems Microsoft heard the voice of customers.

Though network virtualization was introduced with Windows Server 2012, I really don’t think that any of the customer could adopt it and make a production network virtualized. The main road block was network virtualization gateway. As I mentioned in one of my previous post, lot many main stream networking giants are coming up with network virtualization gateway appliance for Hyper-V. But that could be an additional investment and may not be an easy option for everyone.

Even, We had unofficial information that Windows 2012 R2 will fix-up these mess. And seems its true. Windows Server 2012 R2 is coming up with an inbuilt gateway which is capable of Multi-tenant multi-site VPN gateway, NAT gateway for internet access and forwarding gateway for within the Datacenter.

Cheers !


Awaiting Windows 2012 Server R2

Its just amazing that Microsoft has significantly improved on the updates and release frequency. We got Windows 2012 Server in Mid of 2012. Its almost an year and Microsoft has announced the Release 2 for Windows Server 2012.

I am also keen to know how well Windows Server 2012 R2 improves specific to HyperV. As per the information posted on Microsoft blog, few of the new features with Windows Server 2012 R2 are

Live migration compression: Compresses virtual machine during live migration to improve migration speed. Yet to get clarity on this. But my assumption is that this will compress the Live Migration traffic so that the data transfer will happen quickly and the overall live migration time will be improved.

Hyper-v Replica:  Hyper-V Replica provides a cost-effective way for SMBs to implement disaster recovery/business continuity scenarios. Extended replication, now add a second replica to add extra protection for your VM at offsite location or hoster. Finer grained control of replication, now choose 30 sec interval or 5 minutes (default) For other scenarios choose 15 minutes.  Windows Azure will support orchestration of recovery using Hyper-V DR replica’s and system center VMM on premise.

Dynamic memory for Linux guests: Automatically reallocates memory between virtual machines that are running Linux as a guest OS on a Hyper-V host. This is one of the feature I wished to have. I am sure that with this feature, the Physical to Virtual ration will improve drastically in an environment where we have Linux VMs.

Online VHDX resize: Online VHDX resize allows a virtual SCSI disk to either grow or shrink the VHDX file whilst attached to a running virtual machine. Simply Great !

More to come soon !




F5 Big IP Announced NVGRE Support

F5 announced their road map on supporting network visualization for Hyper-V.

F5® BIG-IP® hardware will support NVGRE gateway functionality beginning the first quarter of calendar year 2014. Integration with Windows Azure is currently available on F5’s BIG-IP solutions.

For me, this seems to be an important move as one of the mainstream vendor will be coming soon to support the network visualization initiatives. Lets hope for the best !
