Bhyve progress

Didn't realise things had got this far...

Just hope this (and the comment about getting the changes in by BSDCan) is a sign that big things are starting to come of age in bhyve.

This is good stuff. Awesome.

I can't even start a single core FreeBSD image with bhyve

Do you have the required hardware? You need a quite recent Intel/AMD CPU with "Extended Page Tables" support.

I know, it's an Intel Core i5 with both VT-x and VT-d turned on, so it should be supported. I get some error message about an unimplemented register (from the top of my head). I found the same error on 11-CURRENT where it's supposedly fixed. The patch was MFC'ed to 10-STABLE three months ago. Just finished rebuilding world again with updated sources. If I still get the error tonight I'm going to submit a PR for it.

Edit: Looked up my CPU and it should support EPT. http://ark.intel.com/products/68316

If it's an unimplemented MSR, use the "-w" option so it can be ignored.

But, please file a PR even after this (the register value will be printed out). We don't have access to all types of CPUs so there are always new MSRs sneaking in.

Yes, that was it. I remember trying that too because it was mentioned in the 11-CURRENT PR, didn't work though.

Yeah, I'll refer to the 11-CURRENT PR as I get the exact same values for the MSR. It also had a few commands for extra info, I'll add those too.
