RHEV Upgrade Saga: KVM Client Take II

In my June 2014 RHEV Upgrade Saga article, I discussed how to build a KVM client for your own use. The method used the Q35 (2009) chipset features that were dropped from RHEL 7 KVM as of version 7.1. This has caused quite a few issues with my deployment of a KVM client system. However, since I have Ivy Bridge (maybe Haswell) chips in my SuperMicro 3U KVM server, I also have access to Intel VT-d, as well as to VT-x, AES-NI, and many other useful chipset features. The most important for a KVM client is Intel VT-d, as it allows you to map USB and PCI devices directly to a VM. Continue reading RHEV Upgrade Saga: KVM Client Take II

A Quiet Rack

My lab environment sits within a closet in my home office. It is not a particularly large closet, but it has been decked out with its own air conditioning, extra insulation in all the walls, and a double-pane insulated external door. The goal? To keep the rack cool, of course, but also to prevent noise from leaking out to the office and the rest of the house. Continue reading A Quiet Rack

vSphere Upgrade Saga: Exchanging HP BL460c G6 with BL460c G8

I recently received a pair of Gen8 blades for my enclosure, and it is time to change out my Gen6 and 7 blades for Gen8. Now, as with every upgrade, a fair amount of planning must occur in order to start this upgrade. I consider it a hardware upgrade, and while it should be straightforward, one cannot simply swap the blades. So much for the easy way.

vSphere Upgrade Saga: Planning for vSphere 6.0

There are many features in vSphere 6.0, such as multi-vCPU Fault Tolerance, that I wish to use for my VMware vCenter Server Appliance (vCSA), as it is the single point of failure. Backups have been made, but they will take quite a while to restore. With the new Fault Tolerance, there is a chance that restore might not be needed, thereby speeding up my recovery. vSphere 6.0 also includes improvements for NSX, VSAN, such as VMCP, long distance vMotion, VVOLs, changes to SSO deployment, and many other existing features, as well as a new web client. All of these make upgrading to 6.0 a worthwhile task. But to do so, you need to first make some preparations. Continue reading vSphere Upgrade Saga: Planning for vSphere 6.0

vSphere Upgrade Saga: Update Order

I have collected quite a few updates over the last few weeks since VMworld ended, and now I should make them. However, the most important non-security update for me is the one for VMware Horizon View. My View environment is old, and though it is maintained, I am in need of several upgrades to Windows, View, and underlying bits. Given that I have nearly everything installed within my environment (except vCAC and vCD at the moment), it is time to find the proper upgrade order.

RHEV Upgrade Saga: RHEL 7 Licensing and RHEV Support

While continuing on my way toward getting a fully running RHEV set up on RHEL 7, I find myself facing two new problems. Neither has a simple solution. The first is the lack of support in RHEV for RHEL 7 as a hypervisor. The second concerns a change in Red Hat’s handling of virtualization licenses. Solving these issues will entail making some hard choices or spending lots of money.
