I'm having similar behaviour with CentOS 6.5 as VM (Centos 6.5 also as host) - one VM keeps crashing during backup 4AM, whenever the IO is high on the disk/host...but this is only 1 VM, and keeps driving me crazy. I have rebuilt it from scratch, and still after few months it started crashing...
I use cloudmonkey to check if VM is running, and start it if not... Problem is I don't know/have any details on WHY this crash happens.. What is the way to debug this crashing, from qemu/libvirt anyone ? Thanks On 11 December 2013 07:30, Pentium100 <[email protected]> wrote: > Hello, > > I have a new problem with Cloudstack.
