Subject [jira] [Commented] (CLOUDSTACK-8762) Check KVM disk files for activity before starting VM
Date Thu, 27 Aug 2015 16:29:45 GMT

    @bhaisaab that's great. So if you think that in the future this implementation might change
it would even be better to create an interface to use in the `LibvirtComputingResource`(and
others). And as first implementation it would get the code you write here to check the file
    When a better implementation comes along, it is easier to switch.

> KVM hosts have real issue with fencing when storage are accessible by multiple hosts
such as in the case of NFS, in which case there is a possibility of qcow2 disks being accessed
by multiple hosts causing disk corruptions. The aim of this ticket is to explore ways to delay
starting a VM if the qcow2 disks/files are still being accessed.
