[Linux-cluster] Fencing Module for VMware ESX and GSX

[Zach Lowry]

Hello!

I recently deployed GFS between 2 virtual machines on a VMware ESX  
server and had a problem because there was no fencing module that  
could handle this architecture. So, using the fence_apc module as a  
template, I wrote a compatible module, fence_vmware. Now, since I  
didn't want to rewrite GFS and recompile to use this new module, I am  
currently using it as a drop-in replacement for the fence_apc module,  
and using the APC configuration syntax. However, this code seems to  
work just right when a machine misses sync, it will log into the  
VMware ESX server and attempt to do a soft reboot of the VM, then a  
hard reboot if necessary. I hope to see this incorporated into the  
GFS tree, but if not it will be available on my website.

Attached is a copy of the source, also available at http:// 
www.zachlowry.net/software.php, along with a sample configuration.
