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 =3D 0 or code =3D 99. Wh= at does these error code mean ?

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. = ------=3D_NextPart_000_00F7_01D1E76E.0E1E4A60 Content-Type: text/html; charset=3D"us-ascii" Content-Transfer-Encoding: quoted-printable

1. =3D We know that xmlrpc =3D and jsonrpc are enabled default in vdsm, vdsm supply these two service =3D in one port or two? What’s the port number and how we can change =3D it?

2. =3D How can we know a vdsm = =3D host can supply an xmlrpc service or a jsonrpc =3D service?

=3D

3. =3D I found that while =3D ovirt engine installing a vdsm host, engine will check whether we are =3D connecting to vdsm which supports xmlrpc only, engine send a =3D ‘Host.ping’ jsonrpc request, why the code will enter =3D into bindingxmlrpc.py?

Did both jsonrpc and xmlrpc will call =3D bindingxmlrpc.py?

4. =3D Then, I just get an =3D json return with code =3D3D 0 or code =3D3D 99. What does these error code = =3D mean ? I can’t find detail in rpcjson Specification(http://www.jsonrpc.org/spec= =3D ification)

5. =3D When installing vdsm, = =3D I got an “Host server117 installation failed. Host is not =3D reachable” error. Debugging code as =3D follows:

Bindingxmlrpc.py

line637 def =3D ping(self):

line638 # print =3D 'os.getuid()',os.getuid() =3D3D 0

line639 # print =3D 'os.getegit()',os.getegid() =3D3D0

line640 api =3D3D = =3D API.Global()

line641 return =3D api.ping()

the api.ping() just open an file and update the file =3D updating time, why these will throw an error code 0 or 99? And I see the = =3D ping() function created file /var/run/vdsm/client.log already exists in =3D os,

the = =3D only difference is the file is owned by root:root , not the vdsm:kvm? =3D Why?

Thank you.

There is a code which peeks the data stream and decides which part of the code should handle the connection.

Older vdsms provide only xmlrpc so this behavior is for backward compatibility. There are two binding modules bindingjsonrpc.py and bindingxmlrpc.py.

This verb originally is used to make sure that any network reconfiguration did not break connection to the engine. During the process of reconfigurati= on engine call ping and vdsm based on file update time can restore old network configuration in case of failure. > the only difference is the file is owned by root:root , not the vdsm:kvm? > Why? > There are 2 vdsm processes running with different user permissions. > > > Thank you. > > > > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > --===============7497513840504475404==--
