--------------------------------------------------------------

I am a bit lost on this thread. Is this issue only happening on upgrade scenario or fresh
install scenario?
For fresh install scenario, since we changed JSON deserialization code in systemvm and management
server, new systemvm.iso needs to be copied to xen host so that newly created ssvm can pick
it up from new code. 
For upgraded scenario, besides copying new systemvm.iso to xen host (this should be done automatically
by mgmt server automatically in connecting to the host), if there are already ssvm existing,
we need to restart ssvm.
If this is only happening for upgrade case, can we close this bug and file a different bug
just for upgrade tp be clear?

> Workaround :
> ==============================
> 1. I tried removing the tags from the host and then restarting the MS, but it didn't
work and i still saw those errors.
> 2. Reboot the XenServer host, this works.
> NOTE : This is a RPM setup not Dev setup
