Subject Re: Issue with SSVM on KVM on master
Date Thu, 18 Aug 2016 14:27:37 GMT
Based on the error message of not being able to find the PremiumSecondaryStorageResource class,
this seems to be the following error (#9 on this page: https://cwiki.apache.org/confluence/display/CLOUDSTACK/SSVM,+templates,+Secondary+storage+troubleshooting):

SSVM agent not running - You see error something like below. Most probably your systemvm didnt
get patched with the agent specific code. This patching happens through the ISO - something
like  systemvm***.iso. Check the size and location of the iso and whether you are not using
the old version iso. For XS its on the host so grep for it and for vmware its on secondary
storage. Do also check that if its vmware that you built your ssvm using noredist flag for
mvn command. For more information check SystemVm.iso

I do see the ISO, though, on secondary storage here:

In /var/log/cloud/cloud.out, I see the following repeated over and over again (below).

I'm running version 4.10.0 of the management server (but the implementation version of the
agent looks to be 4.9.0). I do have systemvm-4.10.0-SNAPSHOT.iso accessible at /export/secondary/systemvm
(/export/secondary is my one and only secondary storage at the time being).

Thanks for the comments, Simon.

I went ahead and tried to telnet into 8250 on my management server (first from the SSVM and
then from another machine). In both cases, this was the result:

telnet 192.168.129.50 8250
Trying 192.168.129.50...
Connected to 192.168.129.50.
Escape character is '^]'.
Connection closed by foreign host.

It looks like a connection was established, but then shortly after closed. Is this what you
were expecting might happen?

Mike,


I wonder whether this could be related to the NIO connection improvements. We saw this type
of problem quite a bit when we were testing it (with all types of agents). Typically you'll
see the agent logs indicating they can't connect to the management server if this is the case.
 Try telnetting to 8250 on your mgmt server and see if suddenly your agent starts to work.


- Si

I should have pointed out that this is a Basic Zone. Also, there is only one KVM host in my
one cluster.

Hi,


I am trying to build a cloud making use of KVM system VMs.


My SSVM VM comes up, but its agent doesn't seem to:

Thoughts on what might be going on here?
