Subject Failed to deserialize json object
Date Wed, 25 Sep 2013 11:12:34 GMT
Dear all,

During my upgrade attempt from CloudStack 4.1.1 to 4.2.0 earlier this week,
I failed on the step when I need to run the cloudstack-sysvmadm script to
restart the system VMs.

nohup cloudstack-sysvmadm -d IP address -u cloud -p -a > sysvm.log 2>&1 &

When I scrutinize the management server's logs, I saw these error messages
related to the console proxy system VM:

====

Could it be the reason why the cloudstack-sysvmadm script is unable to
restart the system VM?

Looking forward to your reply, thank you.

Cheers.
