free hypervisor with ups management, does it exist?
I am currently running ESXi 4.0 and it does not appear to have native support for detecting a power loss on my APC UPS. Nor does XenServer. I would prefer to avoid having to run a physical machine that is connected to the UPS and then runs a script to shutdown the vm's and host.
Is anyone familiar with a configuration using ESXi or XenServer (that does not involve installing a package on the host) and perhaps a UPS with a network interface that would allow the host or a VM on the host to detect a power failure and then shut everything down?
I am willing to buy new UPS hardware and switch to a different hypervisor if someone can suggest a solution that works. Thanks!
