> Key: CLOUDSTACK-1302
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1302
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.0.0
> Environment: Ubuntu 12.04.2 Host, KVM hypervisor
> Reporter: Jason Villalta
> Assignee: Wido den Hollander
> Priority: Minor
> Fix For: 4.4.0, 4.5.0
>
>
> Version 4.0.0 of Cloudstack has a hard coded value of cache=none for virtual
> machines deployed. This causes conflict with filesystems mounted with fuse
> such as ZFS, GlusterFs and CEPH as fuse does not support directio with these
> file systems. When starting VMs libvirt throws an error "could not open disk
> image <disk> Invalid argument"
> Changing the cache= setting to writethough or writeback solves this problem
> but there currently is no way to set this. Ideally this would get set on a
> per datastore basis.
