Re: [ovirt-users] 64 bits oVirtGuestAgent.exe at 99% CPU

Of course, Vinzenz The VM is a Windows 7 (I've tried both 32 and 64 bits, same result). The C:\Windows\SysWOW64\rhev-agent log says: Dummy-1::INFO::2014-07-10 14:35:57,417::OVirtGuestService::80::root::Starting OVirt Guest Agent service After look at the code, perhaps the problem may come on the run() function in OvirtAgentLogic.py def run(self): logging.debug("AgentLogicBase:: run() entered") thread.start_new_thread(self.doListen, ()) thread.start_new_thread(self.doWork, ()) # Yuck! It's seem that Python block all signals when executing # a "real" code. So there is no way just to sit and wait (with # no timeout). # Try breaking out from this code snippet: # $ python -c "import threading; threading.Event().wait()" while not self.wait_stop.isSet(): self.wait_stop.wait(1) Where this "while" is evaluating itself each second... besides the wait function of the python module By commenting thread.start_new_thread(self.doWork, ()) the CPU has a normal level when the service starts, but when we make a petition through the host socket, the VM CPU goes to 100%. Hope this helps, if you need any action from me, please tell me.
