Description yuanquan chen 2012-04-06 07:32:57 UTC
Description of problem:
After registering to SAM and RHEV-M, edit the /etc/sysconfig/virt-who, restart the virt-who service, it's ok. Reboot the rhev-h, edit the /etc/sysconfig/vrit-who, restart virt-who service, some exceptions appear.

Version-Release number of selected component (if applicable):
rhev-hypervisor-5.8-20120403.0.el5_8

How reproducible:
100%

Steps to Reproduce:
1. install rhev-h, boot up and register to SAM and RHEV-M
2. edit "/etc/sysconfig/virt-who" as "VIRTWHO_BACKGROUND=1 VIRTWHO_DEBUG=1 VIRTWHO_VDSM=1 VIRTWHO_INTERVAL=2", restart virt-who as "service virt-who restart", it's ok
3. restart rhev-h, edit "/etc/sysconfig/virt-who" as step 2, restart the virt-who service.
  
Actual results:
Register rhev-h to SAM and RHEV-M, reboot the rhev-h, edit "/etc/sysconfig/virt-who", restart the virt-who service, some exceptions appear.

Expected results:
Register rhev-h to SAM and RHEV-M, reboot the rhev-h, edit "/etc/sysconfig/virt-who", restart the virt-who service, no exception appears.

Comment 2 yuanquan chen 2012-04-09 03:26:33 UTC
I retry the restarting of virt-who and find that the root cause of the exception is that the SAM server can't be resolved by the default DNS server. If we specify the proper DNS server in rhev-h, there's no any exception.
