[CentOS-virt] Machine freeze

2009-04-03 Thread Maros TIMKO


Hi all,

we are running CentOS 5.2 Xen virtualization system with the latest CentOS 
packages with couple of VMs on DELL PowerEdge. quot;Sometimesquot; the whole 
machine freezes without anything in log files, anything on the console. 
quot;Sometimesquot; really means we cannot define why or when. Sometimes the 
machine was idle with just one VM, sometimes quite busy with couple of VMs.

nbsp;Has anybody had the same experience? If yes, any hints on how to resolve 
it or how to trace the cause?

nbsp;

Thanks.nbsp;___

Yes,

mem and disk check was also our first thing to do. But it happened on
different machines (1950s and 2950s), different BIOS versions and number of
NICs. The freeze situation is unrecoverable - machine replies to pings, but
did not write anything to console. You cannot SSH to it, the only thing we
could do is power down the machine. After that everything is fine.

Thanks.

 The complete freezing of a machine like that sounds like a hardware
 issue to me, most likely the memory. Does the machine unfreeze after a
 while or do you have to power cycle the server when it happens ? I
 would suggest running a memtest.

 Tim

 Hoping the problem  magically goes away  by ignoring it is the
 microsoft approach to programming and should never be allowed.

[CentOS-virt] kernel-vm - humble request

2009-04-03 Thread John Thomas
Look, I pay nothing for an incredible operating system with enormous 
features and stability, so it feels a bit awkward asking for more.

[Sarcasm On]
Now, get going and build me up a 5.3 kernel-vm's would ya? ;)
