All fencing requests go through the opensaf_reboot script today. Have you thought about build-time options for how to link with these two libraries? I suppose the most flexible approach would be build-time options to select which libraries to link with (so you can select to link with just one o

Hi Alex, interesting, I was not aware of ticket #1431! I considered PLM but assumed it involves some more work than the patch I sent out, as this feature is to be delivered in August. The remote fencing patch could be replaced with your PLM solution when it is ready and PLM seems to be the r

Yes, it uses libvirt for all the EE admin operations performed on the virtualized EE. There is no special fencing code in the PLM implementation, even for the current non-virtualized implementation. It's free with the PLM-EE hook in opensaf_reboot. So, if there are cases where opensaf_reboot is

Ok, I see. Will PLM use libvirt for something else than fencing in such a configuration? regards, Anders Widell On 06/30/2016 05:02 PM, Alex Jones wrote: > Hi Anders, > > I have a basic working implementation which uses libvirt, but it's > not yet ready to send out for others to test. It re

Hi Anders, I have a basic working implementation which uses libvirt, but it's not yet ready to send out for others to test. It relies on libvirt to talk to the hypervisor to tell it to fence the node. It uses the current setup in opensaf_reboot which calls PLM. Mathi and I have been talkin

Interesting! How do you intend to implement this? Will OpenSAF rely on OpenHPI for remote fencing also when running inside virtual machines? Does OpenHPI support that today? regards, Anders Widell On 06/30/2016 04:11 PM, Alex Jones wrote: > Hi Hans, > > For what it is worth, there is a ticke

Hi Hans, For what it is worth, there is a ticket (1431) which will implement virtualization of EEs in PLM, which is not currently supported. I am planning on implementing this at some point this summer. That should take care of fencing in a virtualized environment, without this patch, but u
