You are correct. Currently, xCAT uses the 'qemu+ssh' to access the libvirtd, so you need to make sure the ssh has been setup correctly between MN and host (ssh access without password). And I have added a tip in the doc.

While I could connect via virt-manager without issue, I was not able to connect via the ssh method. I resolved it and have moved forward. Maybe it would be good to add this into a FAQ for xCAT/kvm or the page here: http://sourceforge.net/apps/mediawiki/xcat/index.php?title=XCAT_Virtualization_with_KVM#Create_and_Install_Virtual_Machines -Chris --- Christopher D.

I seem to be having troubles talking with libvirt. I tried turning off iptables but that didn't work. SELinux is disabled. # rpower cdmkvm2 status cdmkvm2: Error: Cannot communicate via libvirt to localhost localhost is where my hypervisor is located. Is there some sort of debugging or verbosity I could increase to find out more in xcat? I tried strace, but that's a ton of information that gets harder to parse. All I see in syslog is: --- Jan 4 12:06:41 HOST xCAT: xCAT: Allowing rpower to cdmkvm1 status for root from localhost.localdomain --- Thanks, -Chris ------------------------------------------------------------------------------ Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.
