2 x Server 2008 R2 VM's in a failover cluster, a guest running Server 2008 R2 with SQL 2008 Standard running has saved and then restored the past two evenings at 6pm (doesn't migrate, just stays on the same host).
I have checked scheduled tasks on all the OS's and event logs but nothing to say why this has happened only that it has happened.
One thing worth mentioning, this error appears after restore and another VM on the other host is running large print run. Windows Installer reconfigured the product. Product Name: 64 Bit HP BiDi Channel Components Installer. Product Version: 188.8.131.52. Product Language: 1033. Manufacturer: Hewlett-Packard. Reconfiguration success or error status: 0.
