Description
Description:
I encountered a serious issue in Vbox 5.1.51 (compiled from source, cloned from git 25 Jan 2017), inside a Vbox VM I have Win7x64 SP1 running, everything works fine, I do a snapshot and shut down the OS. If I restore the snapshot and start the Vbox VM, the following error occurs:
cpum#1: X86_CPUID_FEATURE_EDX_HTT is not supported by the host but has already exposed to the guest [ver=17 pass=final] (VERR_SSM_LOAD_CPUID_MISMATCH).
Result Code: NS_ERROR_FAILURE (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
This only happens with VMs with more than one CPU. If I discard the snapshot I can start the machine with two CPU without a problem. If I se t it to one CPU, the snapshots are working.
The Vbox app is running inside an Ubuntu 16.04.1LTS which is running inside VMware Worksation VM(details below).
Vbox running inside an:
Ubuntu 16.04.1 LTS Linux ubuntu 4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6 17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
