11. Allows THIN_CLONE cloneType On NFS While thin cloning is only supported on OCFS2 file systems and the Oracle VM Manager Web Interface does not provide the option to create a clone storage mapping for a thin clone on an NFS file system the Oracle VM Manager Command Line Interface does not prevent you from doing this Therefore a command similar to the following succeeds OVM gt create vmclonestorageMapping name clonestoragemapping cloneType THIN_CLONE vmDiskMapping 0004fb0000130000ef5b6a1671333bb3 repository nfsrepo on vmclonecustomizer name clonecustomizerl However when a clone is created using the clone customizer that this clone storage mapping is attached to the action fails due to the fact that the clone target does not support the thin clone cloneType OVM gt clone vm name vml 0 destType vm serverPool MyServerPool cloneCustomizer clonecustomizerl targetRepository nfsrepo Command clone vm name vm1 0 destType vm serverPool MyServerPool cloneCustomizer clonecustomizerl targetRepository nfsrepo Status Failure Time 2014 05 06 22740723 7 55 PDT JobId 1399441233570 Error Msg Job failed on Core OVMRU_007013E Cannot thin clone System img 2 to nfsrepo The clone target does not support thin cloning Tue May 06 22 40 33 PDT 2014 This is expected behavior but the flexibility offered by the Oracle VM Manager Command Line Interface is inconsistent with the Oracle VM Manager Web Interface and can result in misconfiguration by a

IP addresses as separate access hosts for example to provide access to different Oracle VM Servers via different paths As a result the same file system would correspond with two different storage object entries each with a different path related to each of the IP addresses As a storage server can only be represented by one object this configuration is not supported in Oracle VM Release 3 3 Workaround Configure only one access host per storage server 6 101 x86 Only Multipath SAN Boot with Single Path Causes Kernel Panic or File System to be Read Only On a multipath SAN boot server with only one active path from server to storage there is a potential risk of kernel panic or the file system becoming read only when doing storage rescans This occurs because multipath SAN boot is only supported with full path redundancy A minimal full path redundancy configuration can be illustrated as Server BAL EC Swaeten sos Storage covtroller pores Storage controller 2 portl Server BAZ EC switcr 2 storage controller porez Storage controller 2 port2 Workaround Configure multiple paths to the file systems instead of a single path Bug 13774291 6 102 x86 Only Multiple Paths Used in Multipath Environments on Oracle Pillar Axiom Storage When performing a fail over for example by disabling one protocol such as Fibre Channel the paths are grouped and the traffic flows through all protocols for example both
13. Not Reliable in Virtual Machine Console Non US keyboard mappings do not behave predictably in the virtual machine console available in the Oracle VM Manager Web Interface To ensure the best possible behavior within the Virtual Machine console it is advisable to set all keyboard mapping options en us on your virtual machines and to use a US keyboard when working with the virtual machine console This is not a requirement but currently not all keyboard mappings behave as expected within the virtual machine console Bug 18089107 6 16 Some x86 Specific Virtual Machine Parameters Are Modifiable for Guests Running On SPARC Some x86 specific parameters for virtual machines are not greyed out and are modifiable when a virtual machine is configured to run on a SPARC based server pool These parameters appear in the Create Virtual Machine and Edit Virtual Machine dialogs in the Oracle VM Manager Web Interface and include settings like the Keymap Mouse Device Type Domain Type Priority and Processor Cap Changing any of these parameters for a virtual machine running on a SPARC server pool has no effect on the virtual machine but may generate a job that is processed by Oracle VM Manager to change the representation of the virtual machine object within the Oracle VM Manager database The job usually completes successfully Bugs 18788652 18715655 6 17 Installer Text for Solaris 10 is Unreadable in the Serial Console The text in the Solaris 10 ins
14. Oracle VM Agent now uses SSL certificates to authenticate requests from Oracle VM Manager when an Oracle VM Server is discovered This reduces the possibility that a malicious user can perform a brute force dictionary attack to authenticate against an Oracle VM Server that is under the ownership of an Oracle VM Manager instance Furthermore certificate based authentication can be used for all Oracle VM Web Services API requests to ease automation while retaining a better security model for authentication See Setting up SSL on Oracle VM Manager in the Oracle VM Security Guide for more information on SSL in Oracle VM Usability and Serviceability New Virtual Machine Console The virtual machine console has been redesigned to use JavaScript and HTML5 features There is no longer any requirement to install or run software locally on the client computer The new console runs within the web browser and only requires that the browser is capable of supporting the technologies used Most modern browsers are supported This change reduces complexity and provides a more reliable console tool See Accessing the Virtual Machine Console in the Oracle VM Concepts Guide for more information on the virtual machine console Virtual Machine Configuration File View It is now possible to view the virtual machine configuration file for any virtual machine directly within the Oracle VM Manager Web Interface and Oracle VM Manager Command Line Interface to provide more tr
