Just some random things in lieu of an actual post.

• Vmware: DV switch can’t be assigned to a VM in the classic client connected directly to a host. Be aware if you’re cold migrating a vcenter VM (eg moving into a cluster with a lower EVC level).
• Don’t update an ipad over an Anywhere USB device. Windows can see it once it reboots, itunes can not, so you end up having to do a full recovery which takes ages (and you did take a full backup first right, oh and you can’t do the recovery over the Anywhere USB either).
• Vyos is a powerful linux based router platform. Getting it under control was worth the slightly steep learning curve, once over the initial documentation related hump it’s all good. I’m considering a full post about this soon.
• Late last year I got the new Kindle Paperwhite (2013) from a local retailer. Compared to the previous one I have (the kindle 2 which is still good) this is so much better. Much faster, the light is amazing and wifi sync finally. Wifi sync and the light were my main reasons for buying it. Since buying it I think I’ve read about 6 books which is just unheard of for me. Though that could be a side effect of how much traveling I’ve been doing.
• I’ve drafted a post about my experiences with disk drive lifespans. I’ll probably post it soon.
• I reinstalled my desktop again and now I’m running full disk encryption. We’ll see how that goes.
• Did a bit more work on the home vmware lab. I think all the issues I had before have been sorted which is good because it gives me time to focus on more interesting stuff.
• Sold the Surface and got an Asus Transformer T100. So much more usable in comparison (it’s x86 based vs the surface being arm based) The battery life is nearly the same. Unfortunately the screen isn’t quite as bright but it’s good enough and cheap enough. A perfect travel companion, I take it with me on all my trips as I can remote anywhere over any protocol with it compared to the fairly locked down Surface. Even the surface being jail-broken you still lack apps being compiled for arm.

I’ve been doing a fair bit of VMware stuff at work lately and thought it was about time I upgraded my lab to ESXi 5.5. My reasons for holding off was because the 8168 driver was removed from the released iso and they’re the only nic’s I have in my machines. Fortunately adding the driver in turned out to be very easy.

First up I had to upgrade vcenter. I use the appliance for simplicity however I’m considering moving to the windows version running on a 2012R2 machine to reduce overheads (yes the appliance uses too much ram). All I did for this was deploy a new appliance on a new IP and connect all my hosts to it. I had to recreate datacenter/cluster level stuff but there’s not much configured there so that’s fairly easy. Also realise as this is a management level connection the running vm’s all keep running without issue.

Then to update ESXi I simply followed instructions found online and slightly modified to use the latest release available.

Using VMware PowerCLI create a custom image with the extra driver package which fortunately is still in the online repo. Note I said PowerCLI, not PowerShell. If you run PowerShell instead you’ll need to “Add-PSSnapin VMware.ImageBuilder” first.

Add-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml 
Get-EsxImageProfile -Name "*5.5*" | Format-Table -Wrap -AutoSize
#from the output of that select the newest profile name and use that below, in this case ESXi-5.5.0-20131204001-standard
New-EsxImageProfile -CloneProfile "ESXi-5.5.0-20131204001-standard" -name "ESXi-5.5.0-20131204001-DS61" -Vendor "tardfree.net"
Add-EsxSoftwarePackage -ImageProfile "ESXi-5.5.0-20131204001-DS61" -SoftwarePackage "net-r8168"
Export-ESXImageProfile -ImageProfile "ESXi-5.5.0-20131204001-DS61" -ExportToISO -filepath C:\Temp\ESXi-5.5.0-20131204001-DS61.iso

Then I realised that’s fine for manual upgrades done from the console but I wanted to try updating remotely (sadly I don’t have out of band access to all my boxes). Fortunately that’s easy too.

Before attempting an upgrade though, it’s always wise to backup your configuration. I recently used this to rebuild a host when it’s boot media died. Again, from PowerCLI:

Connect-VIServer -Server vcenter -User root
#obviously use your vcenter hostname if it's not vcenter
Get-VMHostFirmware -VMHost vs1.tardfree.net -BackupConfiguration -DestinationPath c:\temp

Then to perform the in-place upgrade, from the ESX shell (ssh into the hosts) run the following. This opens the firewall to allow outbound http requests, and then downloads and applies the update. Note the same profile name as in the above iso creation. Also note the update command not install command. Update keeps vibs that aren’t present in the image, install does not. So in my case install would throw out the network driver I need as it’s not in the new image profile.

esxcli network firewall ruleset set -e true -r httpClient
esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-20131204001-standard

After running that it tells you a reboot is needed, so reboot it and hope for the best. So far all of my physical hosts have come up fine (one left to reboot) and 4 out of 5 virtual esx hosts did. The one that failed pink screened on me and then recovered to the previous version partition. I’m yet to figure out quite why, so I might just reinstall it (all 5 of these hosts were built from the same template and have identical configuration).

Anyway that’s enough for now.
