Couple of VMs consumed all the resources and suddenly I was not able to access the OVMM console through browser and when I rebooted it by 'xm reboot vm.cfg' command the vm is down.
Other VMs are running OK.
And 'now when I want to start the VM running OVMM by xm -c vm.cfg' command I get the below error message -
[root@OVM05 VirtualMachines]# cd 0004fb000006000032f80b7ec3102f04/
[root@OVM05 0004fb000006000032f80b7ec3102f04]# ls
vm.cfg
[root@OVM05 0004fb000006000032f80b7ec3102f04]# xm create -c vm.cfg
Using config file "./vm.cfg".
