I am running Windows Server 2012 R2 Host machine. In Hyper-V, I created a WS 2012 VM. The VM starts out OK, but after a few hours of work (configure and install SharePoint 2013), starts throwing errors (Machine had to re-boot). Eventually, the VM becomes unstable and unable to re-boot. Last attempt threw this error in Hyper-V Event Manager:
'BISP2013' has encountered a fatal error. The guest operating system reported that it failed with the following error codes: ErrorCode0: 0x7A, ErrorCode1: 0x400207A0, ErrorCode2: 0xC0000185, ErrorCode3: 0x57BA6860, ErrorCode4: 0x40F4234. If the problem persists, contact Product Support for the guest operating system. (Virtual machine ID 7E140D89-25B9-4D3B-835B-7BB882C629BB)
This has happened on multiple attempts occasionally ending with Error 0Xc000021a. Creating WS 2012 R2 VMs does not present this problem.
Any suggestions greatly appreciated.
