virtualbox 5.0 is very big improvements for the installation and use with linux VM. Sadly, boinc doesn't recognize the hypervisor so -> hypervisor failed |

I will forward the message to higher up, whomever that is these days. But also know, the old adage on this: "We recommend the VirtualBox version that is included in the recommended BOINC Windows installer, since newer VirtualBox versions do not work correctly for all projects." |

Got answer back from development already. They have released new VirtualBox wrapper applications for BOINC which do work with VBox 5.0 The project will have to update their wrapper applications. |

I build Vboxwrapper 26169 yesterday, which includes the needed changes to support VirtualBox 5.0. You can find them here: http://boinc.berkeley.edu/trac/wiki/VboxApps ----- Rom BOINC Development Team, U.C. Berkeley My Blog |

really great guys for the ultra-fast reply. I know that better to work with the virtualbox included but since i need virtualbox also for other VM with XORG server... as I say virtualbox 5.0 is really a huge improvement for the network drivers installations which don't screw up anymore and also for Xorg virtualization, at least for those two things. So as users we don't have to do anything? only project as atlas etc have to change their files? |

So as users we don't have to do anything? only project as atlas etc have to change their files? You best notify the affected project(s) that there are problems with the present wrapper applications and that there are better ones available. Not everyone reads the email lists. But yes, essentially you do not have to download these files, the project will have to incorporate them. |

I build Vboxwrapper 26169 yesterday, which includes the needed changes to support VirtualBox 5.0. Thanks Rom! I did a test with combo Win7 64bit, vboxwrapper 26169, VirtualBox 5.0, BOINC 7.4.18 and project VirtualLHC@home. Result: http://lhcathome2.cern.ch/vLHCathome/result.php?resultid=5043240 Vbox_job.xml: <vbox_job> <os_name>Linux26_64</os_name> <memory_size_mb>1024</memory_size_mb> <enable_network/> <enable_floppyio/> <enable_remotedesktop/> <enable_cern_dataformat/> <job_duration>86400</job_duration> <minimum_checkpoint_interval>60</minimum_checkpoint_interval> <pf_guest_port>80</pf_guest_port> <pf_host_port>7859</pf_host_port> <disable_automatic_checkpoints/> <enable_vm_savestate_usage/> </vbox_job> I made a manual snapshot in between (task suspended, LAIM off). Job ran fine and everything cleaned up after the finish. I've stderr.txt, VBox.log's and VBoxStartup.log available, if interested. |

I discovered one issue in my former mentioned setup: Configuring the VM with 2 cores by adding <avg_ncpus>2.0</avg_ncpus> in the app_config.xml (what was working fine in VBox 4.3.28 with VBoxwrapper 26167) results in: - VM created with 2 cores - VM booting - During boot phase stops somewhere, although VBoxHeadless.exe keeps on running using a full core. - Not doing real work. Maybe this message has something to do with it: 00:01:19.883176 ERROR [COM]: aRC=E_FAIL (0x80004005) aIID={4afe423b-43e0-e9d0-82e8-ceb307940dda} aComponent={MediumWrap} aText={Unknown exception 00:01:19.883176 F:\tinderbox\win-rel\out\win.amd64\release\obj\VBoxAPIWrap\MediumWrap.cpp[2245] (long __cdecl MediumWrap::GetEncryptionSettings(unsigned short **,unsigned short **))}, preserve=false aResultDetail=0 My own Linux-VM with 4 cores on my Windows host is running fine with VirtualBox 5.0, like the projects VM with 1 core is doing OK too. |

I discovered one issue in my former mentioned setup: Does that always happen when a new job is received? Or only after restoring from a checkpoint? ----- Rom BOINC Development Team, U.C. Berkeley My Blog |

I discovered one issue in my former mentioned setup: With every new BOINC-task received and app_config configured as described, the 2-core VM is created and booting, but unusable. Checkpoints (I suppose in this case you mean snapshots) aren't made. Selected 2 of those problem tasks returned by ending gracefully: http://lhcathome2.cern.ch/vLHCathome/result.php?resultid=5044490 http://lhcathome2.cern.ch/vLHCathome/result.php?resultid=5045098 |
