Created attachment 612371 [details] heartbeat_and_shutdown_status_info Description of problem: Install a guest rhel5.9 with kernel2.6.18-339.el5 on Hyper-v platform,heartbeat and shutdown service is ok by view the status on Hyper-V manager and click the button"shutdown" on the Hyper-V manager,then on the guest rhel5.9 execute the command "rmmod hv_utils",the heartbeat status on the Hyper-V manger wil become to "lost communication",(hearbeat_and_shutdown.png)click the shutdown button the shutdown button will not work with a pop-up window(hearbeat_and_shutdown.png),then execute the command "modprobe hv_utils""lsmod|grep hv_utils"the modules is loaded for a while,but the status of heartbeat keep "lost communication"and button "shutdown" on Hyper-V manager still keep the window. Version-Release number of selected component (if applicable): The Hyper-V:6.1.7600.16385 The Hyper-V guest:rhel5.9 kernel:2.6.18-339.el5(x86_64) How reproducible: 100% Steps to Reproduce: 1.Install the Hyper-V guest with kernel2.6.18-339.el5 2.login the guest,execute the command "rmmod hv_utils" 3.on the guest,execute the command "modprobe hv_utils" 4.check the status Heartbeat on Hyper-V manager,and shutdown the guest by click Hyper-V manager "shutdown" button. Actual results: After step 4,the status for heartbeat is "lost communication",click the Hyper-V manger "shutdown"button cannot shutdown the guest. Expected results: when modprobe the hv_utils the status for heartbeat is "ok",click the Hyper-V manger "shutdown"button can shutdown the guest normally. Additional info: After reboot the Hyper-V guest,the Heartbeat status on Hyper-V will be ok and shutdown button on Hyper-V function will work.
During the test of kvp deamon, if remove the hv_utils driver and load it again in the guest, fail to get the Linux guest information from GuestIntrinsicExchangeItems on host with the guest hypervkvpd service running. Both x86_64 guest and the i386 guest meet this problem. [root@localhost ~]# rpm -q hypervkvpd hypervkvpd-0-0.7.el5 [root@localhost ~]# service hypervkvpd status hv_kvp_daemon (pid 8206) is running...
Supplement: The issue exist on Hyper-V guest rhel5.9 with platform i386,i386PAE,x86_64
Closing this bug, since it looks like a (Windows) host bug that RH cannot fix.
