This issue occurs because data written to thevirtual disk might get cached into the service domain before it is effectively writtento the virtual disk backend. This can cause potential data loss if the service domaincrashes while the data is still cached.Oracle (Sun) bug id is: 6684721 (file backed virtual I/O should be synchronous)This Oracle (Sun) bug is fixed in Oracle (Sun) patch 139562-02 that has beenobsoleted by 138888-07.See “Solaris patch requirements” on page 80.A volume can become inaccessible from the guest in the eventof control domain rebootAll access to such a volume hangs if the primary domain is rebooted. This is dueto the vdisk corresponding to the volume does not come back online after thecontrol domain reboots.This issue has been identified and fixed under Oracle (Sun) bug id: 6795836(vd_setup_vd() should handle errors from vd_identify_dev() better)
