The machine was frozen in Ubuntu, and defrosted in OSX. Ubuntu is running OSE from the repository, OSX the current download package.
cpum#1: x86_CPUID_FEATURE_ECX_OSXSAVE mismatch: host=0 saved=1 [ver=12 pass=final]
Can anyone help me out?
This is another error: x86_CPUID_FEATURE_ECX_OSXSAVE, instead of VERR_SSM_LOAD_CPUID_MISMATCH. Perhaps you would be better off opening a new topic here on the forum, not only because it's a different issue, but also because VirtualBox maintainers seem not to care about the original issue (almost 2 years and no responses at all, even with many people reporting the issue and a ticket open... sheesh).
What little help I can offer: I don't think there's any quick way out but discarding the "saved" state and restarting the VM. You can do the discarding via the "VBoxManage discardstate" command. I would make a backup copy of the VM directory before trying that, as there's a chance of corrupting the VM disks by discarding the current state (think about unsaved filesystem metadata in OS in-memory buffers).
