Dear xen-users, I''ve setup cloudStack 2.2.13 with XCP 1.1 as hypervisor successfully, and can operate with some virtual guest in XCP. The cloudStack uses a shared NFS directory as repository to store virtual guest root disk. As an experiment, I have disconnect the NFS connection from XCP host for a while. After 3-5 minutes, the XCP host didn''t respond anymore and after 15-20 minutes, I found it has rebooted. I''ve tried to look into log files in /var/log/* but nothing seems to be related to the problem. I''ve asked for some clues to debug this trouble. Thanks.
