The new Red Hat Enterprise Linux Virtualization Getting Started Guide, which I worked on, is essential reading if you want to find out how to start out using KVM on RHEL 6.

This is going to be mainly about RHEL, but it will also be relevant for Fedora/Debian/Ubuntu users. It’ll be a gentle introduction: technical, but you won’t need to know anything about libguestfs. It’s not a marketing thing.
The conference will be open to everyone. The way these work is you call in to a conference phone number. There will be numbers announced for each country, plus for a few countries there may be toll-free numbers. Also if you have Webex you will be able to follow what’s happening on my desktop at the same time.
There will be an opportunity to ask questions at the end.
The call will be recorded and archived — more details about that afterwards.
To get access to the RHEV-M 3.0 beta, you must have an active Red Hat Enterprise Virtualization subscription. Go to this RHN page to see links to the beta channels. See this page for discussion around the beta. This is the official announcement.
I received the 2 x HP microservers and the 8 GB RAM upgrades today. Although I don’t yet have the disk upgrades (expected next week) I can make a start installing standard RHEL on one of the servers. I’m going to install RHEV-M into a virtual machine on this first server, but I can’t install that yet without the disk upgrade.
Performing the memory upgrade is relatively simple. Once about 5 cables are removed, the motherboard slides right out:
Because these machines have no CD drive, I used PXE to install RHEL 6.1 (on the first server only):
For clarity, this is what I’m expecting the installation to look like right now (I may change my mind in future though …)
To get access to the RHEV-M 3.0 beta, you must have an active Red Hat Enterprise Virtualization subscription. Go to this RHN page to see links to the beta channels. See this page for discussion around the beta. There is also a Webinar taking place today (18th August). Finally here is the official announcement.
RHEV-M requires two physical servers, one running our minimal hypervisor RHEV-H and one running the management console. Starting with RHEV-M 3.0 the management console runs on Linux [PDF] (you can still run it on Windows if you want). The management console can be run in a VM, but it can’t unfortunately be run in a VM on top of RHEV-H because there’s a chicken-and-egg problem that the management console needs to talk to RHEV-H to instruct it to start VMs.
I’m doing this on the cheap, so the hardware I’ve ordered is not the recommended way. Performance is expected to be fairly abysmal.
I ordered two HP Proliant Microservers, and upgrades to the RAM and disks.
|2 x HP microservers
@£250 each inc tax/delivery
|2 x 1 TB Samsung HD103SJ
@£44.80 each inc tax/delivery
|2 x 8 GB RAM
@£67.99 each + £27.20 tax, delivery included
HP have extended the cashback offer on these servers through August 2011, so I should be able to claim £200 back.
Red Hat Enterprise Linux 6.1 is out.
For this release the Virtualization guide was extensively updated. In particular I wrote a section on using libguestfs, guestfish and the virt tools for offline access to disk images.
I also managed to slip in a Perl joke …
Thanks to everyone who came to our Summit talk this year. We must have had over 200 people there.
There will be a video — it’s not up yet.
In the meantime, here are the hand-outs which contain background, documentation and worked examples. Both are PDFs:
