Looks like you’ve got a posix or nfs mount there? Is your gluster storage
domain of type GlusterFS? And make sure you restarted the ovirt-engine after
enabling LibfgApiSupported, before stopping and restarting the vm.
An active libgf mount looks like:
<disk type='network' device='disk' snapshot='no'>
<driver name='qemu' type='raw' cache='none' error_policy='stop'
io='native'/>
<source protocol='gluster'
name='gv1/a10b0cc4-b6ec-4b26-bef0-316e0e7bdcac/images/7e8b2be0-8206-4090-8fa4-c87d81fb5ea0/6b8c2ff9-15f3-47a9-af5d-bb7dea31b59b'>
<host name='gstor0' port='24007'/>
</source>
