Re: [regression] bhyve stopped working

HI Lars,


I just upgraded to r272468 and bhyve stopped working. When I start a VM
(Ubuntu or FreeBSD) byhve dumps core:


 Should be fixed in r272481.

Peter.

Re: VM unrestricted guest capability required

Hi Allan,


If/When bhyve gets the UEFI boot stuff to be able to do 'any OS' (from
my understanding, this is the approach that will be used for Windows),
would that remove the requirement for UG to boot Linux, if it was booted
via UEFI?


 It cements the UG requirement even further: UEFI is a form of BIOS 
ROM, which requires starting the VM in x86 real-mode power-on state.

Peter.

 Plans - most definitely. Progress - not a lot to report at this stage.

 Aargh, looks like the recent ACPI-CA import caused this :( Working on 
a fix now.

I think I answered my own question:

# sudo dmesg | grep UG

VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID

Thanks Peter for the clarification. Is there a way to tell this from dmesg?

Re[2]: VM unrestricted guest capability required

[Евгений IRON]

 Ok

I just tested the same on another server with UG presence and it works great.
Are there any news/plans/progress with possibility to run Windows as guest? 
It's probably the last barrier for me from use bhyve (obviously FreeBSD as 
host) for my farm of VMs in production.

Thank you guys for perfect job.
