I have installed xcp-xapi on ubuntu 12.04, I can run VMs perfectly but I cannot make live snapshots, I receive the following error message:
xe vm-snapshot new-name-label=my_snap vm=482c0f4c-fa7d-67c1-a178-559b81b79ede
Error code: SR_BACKEND_FAILURE_82 Error parameters: , Failed to snapshot VDI [opterr=failed to pause VDI XXXX-XXXX-XXXX-XXXX-XXXX],
