[Xen-users] [XCP] physical server "crash"

[Denis Cardon <denis.cardon@xxxxxxxxxxxxxxxxxxxxxx>]

Hi everyone,

in the last 3 weeks I have had two physical XCP 0.1.1 server "crash" on 
two different machine in the same 3 hosts pool. The VMs happened to 
become unresponsive and I couldn't get the console on dom0, no ping, no 
led blinking and no caps lock led responsiveness.
In the log, before the crash I had a few hours of Balloning message in 
the log. The server still has plenty of RAM left.

At some time in the morning, the HVM11 virtual machine became 
unresponsive and it has been rebooted. The reboot went ok according to 
the log and then there is just syslog -- MARK -- and then nothing else.
XCP local storage on a 16GB flash (no VMs there) and shared storage on a 
iscsi HP MSA san. Cpu model name: Intel(R) Xeon(R) CPU E5520  @ 2.27GHz
I'm planning on an upgrade to 0.5, but I wanted to here from users no 
the mailing list if you have seen anything related.
Thanks,

Denis
