In this comment, Gra asked me to explain why I was fixing up the pegasus implementation in VI3.5 Happy to oblige. What is OpenPegasus OpenPegasus is a free Open-Source implementation of the CIM and WBEM monitoring/management protocols for most Unixes and Windows operating systems. It is so popular that Microsoft is using it in their [...]

3com 4500G switch and ESX portgroups/VLANs
Man, this was not fun at all. On the weekend, had some work to connect ESX to a 3com switch with port trunking enabled, sending out VLANs 10,11,12 through one port. The required config is: interface GigabitEthernet1/0/17 port link-type trunk undo port trunk permit vlan 1 port trunk permit vlan 10 to 12 broadcast-suppression pps [...]
Citrix Xen 4.1 multi-pathing with EMC storage array
EMC does not natively support multipathing via Powerpath on Citrix Xen 4.1 But Linux, does have native multipathing support via the /etc/multipath.conf file: ## This is the /etc/multipath.conf file recommended for ## EMC storage devices. ## ## OS : SLES 9 SP3 ## Arrays : CLARiiON and SYMMETRIX ## ## The blacklist is the enumeration [...]
Installing OracleVM in VMware Workstation
It’s easy enough – download OracleVM from Oracle’s website Install it using the Other Linux 2.6Â (64-bit) OS option in VMware Workstation When it finishes installing, log in as root anddo the following: Run: cd /etc/yum.repos.d/ Run: wget http://vault.centos.org/4.4/CentOS-Base.repo Run: yum -y install rpm-build make gcc After that’s done, install the VMware Tools for Linux [...]
Mirroring our iSCSI SAN, continuing on…
We’re continuing on from this post (The sound of one Right Hand clapping… part 1) and we’re now going to mirror our iSCSI volumes between two iSCSI servers. It’s not fail-over yet – it’s just mirroring for DR purposes, cluster round-robin and fail-over/fail-back will come a little later. So, build two of the iSCSI servers [...]
The art of Xen, and why it’s a pain in the neck.
So, you probably ended up on my blog because you were searching google for VMware issues. Fair enough, but I’m more than just a pretty face – I’m a Linux geek, and that means that I do all virtualization, not just the point and click variety. Today, I was doing a small pilot install for [...]
Site update
Just had an email from Gra. Apparently captcha sucks and is stopping comment posting. And HTML mangles text by removing double-dashes. I’ve uploaded files as required so you don’t have to copy-paste my text blobs any more. Thanks again, Gra
The sound of one Right Hand clapping… part 1
Building an iSCSI server So we’ve all heard about LeftHand Networks’ “SAN” appliance, and the XSI one. High-end SANs, they are not. Some kind of miracle, they are not iSCSI servers are not difficult to set up network-based disk replication is not hard to set up. I’ve heard all about how good these things are [...]
More nonsense with VirtualCenter certificates – part 2
Man, VMware really bit the wrong end of the stick on this one – it’s a pain and causes people to kill kittens. This guide is for how to use Windows Certificate Authority (which requires no enrollment since it’s already domain enforced) and openssl. Again, thanks to Rich from VM/ETC for drawing this to my [...]
The mother of all ESX kickstart scripts… part 2
The below script works better with ESX 3.5, does a few more things and fixes a few minor bugs in the pegasus implementation with HP servers. The below script runs a silent installation of ESX 3.5 and then sets up some default options. The following are assumptions that need to be changed: There are 5 [...]
