SSVM => Agent communication is coming UP again.


Still seeing the connection issue for SSVM/ConsoleSVM.

What systemvm version are you using?

We are using the latest build for master from here;
 http://jenkins.buildacloud.org/job/build-systemvm64-master/

The management head logs this when SSVM/ConsoleSVM attempts to connect;

2014-10-03 17:40:29,443 DEBUG [c.c.a.m.AgentManagerImpl](AgentConnectTaskPool-1777:ctx-a52efbaa) Failed to handle hostconnection: java.lang.ClassCastException:com.cloud.agent.api.StartupProxyCommand cannot be cast tocom.cloud.agent.api.StartupRoutingCommand2014-10-03 17:40:29,565 DEBUG [c.c.a.m.AgentManagerImpl](AgentConnectTaskPool-1778:ctx-33226ba7) Failed to handle hostconnection: java.lang.ClassCastException:com.cloud.agent.api.StartupSecondaryStorageCommand cannot be cast tocom.cloud.agent.api.StartupRoutingCommand

Environment is updated OEL65 for management head and hypervisors,installed from RPMs built from master as of a couple of hours ago.

ACS441 and earlier works in the environment.

I already created an Advanced Zone (simulator) and I'm now running the 69 
Marvin smoke tests again it: VMs being created; etc..

I'm happy again. When both Advanced and Basic zones have been tested against 
both Simulator and XenServer, I will create my PR and send the details about 
the changes to the community for approval.

Cheers,
Wilder

Hi Wido,

Could not do much last night due to other issues.

Just got 8 new commits:

I don't see anything about SSVM, but I already rebased my branch and will give 
it a try.

In case it won't work, I will create a bug, try to fix it and send a pull 
request separately.

Will keep you updated.

Cheers,
Wilder

Thanks for the reply, Wido.

I have to pick up my daughter, but will try the telnet asap.

Cheers,

Hi all,

I have been busy trying to identify why is the SS VM connection to
the host agent broken. Could anyone please give me a clue?


Well, I don't have a clue, but I saw this on master as well yesterday.

What happens if you telnet to port 8250 on the management server? Does
that work or does it close the connection as soon as you connect?

Wido

We have a massive Pull Request to be sent. This morning everything
was working, tested with Basic/Advanced zones with both Simulator and
XenServer. All smoke tests passing (69!). After I rebased and got 26
commits from Master and went testing everything again, just started
facing this problem.

Without agent connection there are no templates ready. So, I cannot
do anything.

In order to prove that the problem was introduced by one of the 26
commits I got this morning, I checkout a branch I have - before the
rebased - and tested it again. All fine! When I get the new branch
- rebased with the master's 26 commits - agent connection is broken.

Unfortunately there is no stack trace/complains... it simply doesn't
connect.

Does anyone have any idea? I really appreciate if someone can give me
a clue.

With kind regards, Wilder
