VT-x and Vt-d issues

[Socratease]

I have a an issue where I cannot start a VM. I have read that I do not have GU this the out put VT-x: PAT,HLT,MTF,PAUSE,EPT,VPID I have a Supermicro MB with a Xeon 3440 cpu and 16 gig of ram. VT-x is enabled in the bios, What else should I look for?

Your processor is too old to support bhyve and I don't think your platform supports any CPUs that do support bhyve.

I doubt that's it. The 3440 supports both VT-x and VT-d. I had it running in a VM on ESXi on a much older xeon chip with no issues.

I had some issues with bhyve on my supermicro Xeon-D, but I just looked at the logs and it was an easy fix once I googled the error message.

I suggest you do the same.

The 3440 supports both VT-x and VT-d.

Not enough. Bhyve requires Extended Page Tables with Unrestricted Guest support, which was introduced in the 32 nm Xeons whose name I never remember. The Nehalem die shrink.

Ok what logs should I look in and what should I look for.

From a shell run kldload vmm

Also this: https://www.freebsd.org/doc/handbook/virtualization-host-bhyve.html

The bhyve design requires a processor that supports Intel® Extended Page Tables (EPT) or AMD® Rapid Virtualization Indexing (RVI) or Nested Page Tables (NPT).

Pretty sure that's correct. It was in this era that virtualization was really starting to take off.

Ok I just tried this on a different motherboard x8ste with an i7 960 and I am still getting the same thing. when I run the command grep VT-x /var/run/dmesg.boot I get VT-x: PAT,HLT,MTF,PAUSE,EPT,VPID as you can see there is no UG any ideas

What part of "you need Unrestricted Guest" do you not understand?

Lucky for you, there are LGA 1366 CPUs that support it, namely the aforementioned Westmeres. IIRC, they were the i7-980X and i7-990X. The X stands for Xtreme, as in "Xtreme cost back in the day".

Thank you for your help

What about the i7 975 extreme will it work

What about the i7 975 extreme will it work

In 2010, Westmere added support for launching the logical processor directly in real mode – a feature called "unrestricted guest", which requires EPT to work.[27][28]

You tell me.

Ok got the i7 980 extreme installed and I can now start the VM. Now when I try to connect to the VM with VNC client it asks for a password. I can't find any place in FreeNAS to set a password for the VM any suggestions

 

[kdragon75]

Did you check the manual for your version of FreeNAS?

Sorry I was able to figure it out
