You are standing in an open field west of a white house, with
a boarded front door.
There is a small mailbox here.
Jason’s post on VMware reminded me of something that I wanted to post a while back. Not widely known, both VMware and Microsoft offer free and available to anyone, virtualized “hands on labs” on some or most of their products. Don’t think of them as videos or scripted presentations. They are in fact real virtual machines with real software you can play with. VMware HOLs for instance include putty.exe that allows you to SSH to the ESXi host to hack it.
If you don’t want to spend hours installing and configuring all this stuff and just want to learn the essence or gain some experience with enterprise technologies without breaking a bank I highly suggest to check them out. Also VMware labs let you preview upcoming technologies which are not yet available on the market!
The first stumbling block was installing vSphere. The 2008r2 server that I’ve been given access to is part of a domain, but I’ve only got local access to the server. The annoying part is trying to logon right after install. My Windows user ID doesn’t work, and logging in as ‘admin’ or ‘Administrator’ doesn’t work. Thankfully I found a hint, to install SQL Management Express to mine the VPX_ACCESS table (my SQL Express instance was \VIM_SQLEXP), and discover that the Administrator logon is
Now with that in place I can now logon to my vSphere.
The next fun is configuring the ESX VM.
By default it’ll try to DCHP itself. Which is great if you have DHCP, but in my small test area on the cloud I don’t have DHCP.
One huge pain I find is that you have to manage version 10 VM’s through the web UI, which let’s face it is dreadfully slow. Also it looks like you still need the ‘fat’ client to manage storage. Ugh.
I’ll probably update this more the further along I get.
I got sent a quick heads up about a post on firstwork systems, where the author details the steps needed to install, and boot up the installer, and then get the rest of it running.
Very cool stuff!
I pulled down debian-5010-alpha-netinst.iso, and extracted /boot/vmlinuz & /boot/initrd.gz .. Decompressed vmlinuz, and booted away! For anyone who want’s it, my minimal install is here. All things considered, it works well!
$ ./qemu-system-alpha -hda alpha.disk -kernel vmlinux -append ‘console=ttyS0’ -initrd initrd.gz -L pc-bios/ -nographic -net nic -net user -drive file=debian-5010-alpha-netinst.iso,if=ide,media=cdrom
