I am repeatedly seeing this message:

1/10/2015 10:23:09 AM | ATLAS@home | task postponed 86400.000000 sec: Communication with VM Hypervisor failed.

Tasks are not being processed. I am using VM Box 4.3.12. What is happening here?

Thanks for any help.

Hi,

Check if you have HyperV installed and uninstall it.
I had the same issue, the Boinc client had shown this error message. Then I've checked the Virtual box console, there was another nice error message, saying that 64bit hyper-visor is not available. I've found the root cause in Virtual Box forums.

If you need both, you can introduce a "switch" to temporary disable Hyper-V to run VirtualBox VMs.
