XenServer 6.5.0 tapdisk experienced an error

xenserver

I have just deployed XenServer 6.5.0 on a physical box. I connect to it with XenCenter client. I am able to create a VM, but when i start it, I get the following error: tapdisk experienced an error. The server has SAS harddrives (RAID 0) and the CPU knows virtualization.

The logs show this:

I would appreciate any advise because I was unable to find anything related to this on the web.

I have experienced the same error, so start try take some informations.

When you do the upgrade seme VM's lose the Xen Drivers for keybord and DVD driver, so can't detect it, specially if you did the upgrade with xentools.iso on it. To solve that i remove the VM, but not the disks, so i create a nev VM and atached the disks, worked for me.
