[jira] [Reopened] (CLOUDSTACK-1302) Add per storage setting for cache="none/writeback/writethrough" options for VMs on KVM hypervisor
[ https://issues.apache.org/jira/browse/CLOUDSTACK-1302?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Wido den Hollander reopened CLOUDSTACK-1302: Not fixed completely. With my latest commit it fixes that the KVM Agent actuallt gets the correct data, but setting it through the UI doesn't work yet. I also found out that when attaching a disk the cache setting IS send to the Agent, but it doesn't apply it. > 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 >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.
