Jason Villalta created CLOUDSTACK-1302:
------------------------------------------
Summary: Add per storage setting for
cache="none/writeback/writethrough" options for VMs on KVM hypervisor
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
Priority: Minor
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.
