Today Red Hat announced the release of its much anticipated product, Red Hat Enterprise Virtualization for Servers. This product includes two components: Red Hat Enterprise Virtualization Hypervisor (aka RHEVM) and Red Hat Enterprise Virtualization Manager for Servers (RHEV-M), the product for managing your virtual infrastructure. As a sidenote, Redhat’s other virtualization product called Enterprise Virtualization for Desktops still remains in private beta today and is expected to be released in early 2010.
In case you missed the announcement on the kvm mailing , sheepdog is a new third party open source project around kvm providing distributed storage management features. Sheepdog provides high availability to kvm guests by providing block level storage volumes to virtual machines similar to Amazon EBS (Elastic Block Storage). In fact one of the items on the sheepdog project todo list is to support the Amazon EBS API. Sheepdog is designed to scale to hundreds of nodes. You can think of this technique as striping your virtual disk data across multiple nodes similar to what raid does.
VMware does a great job with this whitepaper trying to convince their customers that Oracle will indeed support VMware technologies running Oracle even in light of Oracle’s support policy that explicitly states Oracle will not certify or support VMware.
The virtualization platform focus for the purposes of this paper is on VMware’s Virtual Infrastructure 3 and Linux-based virtual servers. However, much of the information contained herein has analogues in Windows services as well.
In fact, most medium-size infrastructures that are not virtualized are likely to only use 15 to 20% of their available computing resources on a daily basis, leaving many servers largely idle. Implementing a virtualized environment may result in much greater use of available resources while still reducing costs.
Please join me in my upcoming EMC Live! event. I will be presenting on Efficient and High Performance Virtualization of Oracle Database Environments using vSphere, similar to my presentation at VMworld in September. However, I have added significant material, so those who saw the VMworld presentation should still join this webcast. Anyone who is interested in virtualization of Oracle database servers should find this presentation interesting as well.
To provide enterprises with virtualization management capabilities, Citrix offers Citrix Essentials for XenServer and Hyper-V in Enterprise and Platinum editions. What's interesting is that the pricing for the Hyper-V version is actually cheaper than it is for the XenServer version. In essence, Citrix is incentivizing customers to go with Hyper-V.
As of October 22, 2009 the per-server pricing is as follows:
If you use Amazon’s EC2 service and are thinking of migrating your virtual machines to KVM, there’s a howto tutorial available at layerboom’s website. I was contacted by layerboom with this tutorial to share and think it’s useful information you might be searching for someday. I haven’t tested this so I can’t comment on how it works but if you need to do this conversion give this procedure a try and see how it works for you.
Yesterday saw the release of Proxmox 1.4 which is the first stable release featuring iSCSI, NFS, LVM, DRBD storage replication in active/active mode and live migration for KVM. Proxmox VE is a very light-weight Debian-based distribution that includes a kernel with support for both KVM and OpenVZ. Proxmox seems to be developing at a steady pace and building a strong community. The storage features included in this latest release are features that KVM users will find very useful for disaster recovery applications.
