Re: XEN | CentOS | Cloud 4.2 | Error Message - Agent Disconnected.

Dan,

No insult taken, I placed the vhd-util not in /opt/cloud/bin -- but, asthe directions say into:/usr/share/cloudstack-common/scripts/vm/hypervisor (on the managementserver I did this)


Is this still the common place for this file, or?

easiest is to check the xen installation for cloudstack components. It
looks like something is missing there. I don't want to try and insult
you but did you throw vhd-util in /opt/cloud/bin? This is a long shot
as SetupAnswer is part of the core and is created by the xen agent for
your hypervisor which is running in the management server. The agents
sends a command to the hypervisor and gets a different type of answer
then it expects.

Can you file a bug and track whatever you find in there?

And if you re-install please try the 4.3 release candidate to see it
is in there still.

regards,

Thoughts on how to proceed past this point? A reload of both XEN & Cent? Or,
should I revert to what I know works rather well, Cloudstack & KVM? :)

This is a fresh install of both Xen & CentOS. What I am attempting to do
is
make the primary IP address 10.x IP and the secondary public 96, or 196
subnet. I VPN'd into the management server proceeded to set it up
database,
vdh-util, etc, marked my traffic at Xen, setup mount points, and then
went
to the UI to proceed to set it up. All IP information aside from the
obvious
public was 10.x nature.

But looking at the error again, it seems as though UUIDs are being
overwritten and perhaps there are segments of a previous setup, so I see
where that came from; but no... it's 100% (well when I got the error) it
was
100% brand new.

Did you upgrade this env? My first thought would be that a component
is left behind. The class cast exception makes me think along that
line.
