1. We know that xmlrpc and jsonrpc are enabled default in vdsm, vdsm
supply these two service in one port or two? What's the port number and how
we can change it?
2. How can we know a vdsm host can supply an xmlrpc service or a
jsonrpc service?
3. I found that while ovirt engine installing a vdsm host, engine will
check whether we are connecting to vdsm which supports xmlrpc only, engine
send a 'Host.ping' jsonrpc request, why the code will enter into
bindingxmlrpc.py?
Did both jsonrpc and xmlrpc will call bindingxmlrpc.py?
4. Then, I just get an json return with code = 0 or code = 99. What
does these error code mean ? I can't find detail in rpcjson
Specification(http://www.jsonrpc.org/specification)
5. When installing vdsm, I got an "Host server117 installation failed.
Host is not reachable" error. Debugging code as follows:
Bindingxmlrpc.py
line637 def ping(self):
line638 # print 'os.getuid()',os.getuid() = 0
line639 # print 'os.getegit()',os.getegid() =0
line640 api = API.Global()
line641 return api.ping()
the api.ping() just open an file and update the file updating time, why
these will throw an error code 0 or 99? And I see the ping() function
created file /var/run/vdsm/client.log already exists in os,
the only difference is the file is owned by root:root , not the vdsm:kvm?
Why?
Thank you.
