I have recently pushed the main ESX host for TNS to 70% overcommit on RAM, since upgrading to 4.1. Interestingly (expectedly), the performance now is the same as it was on 3.5 with 2 fewer VMs and only 50% overcommit. But, it’s still pretty poor in the “Lab” performance pool, even after changing that pool from “low” to “normal” shares. So we finally ordered new memory, doubling the server to 16gb. It goes in Sunday night, so we’ll see how things perform next week when Rob’s on site with customers.

I just finished my upgrade from Kubuntu 8.04 to 8.10 this past week (since I had downtime from work, I could afford to break things for a few days). The upgrade went great, and I’ll write about it shortly, once I get used to the newness.
Anyways; Workstation 6.5 has been giving me problems. Because of the newness of KDE4, I initially thought it was a KDE problem, but it turns out it’s something between Workstation 6.5 and Ubuntu 8.10. I just ran the “adapt –dist-upgrade-devel” command from the Ubuntu wiki to upgrade, and upon reboot, I couldn’t “ctrl-alt-ins” or “ctrl-alt-del” to log into my Windows VM, my “Windows/Start” key on the keyboard wouldn’t respond, and my arrow keys wouldn’t work. Incredibly, when I’d hit the “down” arrow, I’d get the Windows Start menu pop up!!
Fix is easy, edit /etc/vmware/config and add the line below like:
sudo vim /etc/vmware/config
:$
A (that's vi-command for "go to the end of the file, and start writing a new line")
xkeymap.nokeycodeMap = true
Have to restart your VMs for this change to take effect. Thanks to Duncan Epping for this fix (he posted it in the forums, where I found it).

VMWare Workstation 6 – Kernel 2.6.22 on Ubuntu Gutsy
Posted by Robert under Linux, VMWareLeave a Comment
I upgraded my Dell D620 from Feisty to Gutsy this weekend, which included an upgrade to kernel 2.6.22. Every time theres a kernel upgrade, VMWare Workstation needs to be reconfigured with vmware-config.pl. This isnt an issue normally, but today it was. Thanks to Chris Hope with Electric Toolbox I was able to fix the problem quick and easy.
For completeness the error I was getting was the same:
/tmp/vmware-config1/vmnet-only/userif.c:630: error: const struct sk_buff has no member named h
when trying to build the VMNet module – VMMon built and inserted perfectly. Downloaded 6.0.1 and installed it, and Im back and in the game.
