Hi Pete,

Sep 10 03:25:01 bells kernel: vmx_init: processor does not support desired basic capabilities

 ^^^  This is what's causing the issues, and is covered in the first bug report I mentioned (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203994)

 Would you be able to dump the MSRs for the FreeBSD guest as mentioned in the bug report ?


Ah I see - once I realized we had a newer kernel I didn't focus too much on the first bug - here's the MSR's


MSR 0x480: 0x00981000 0x11e57ed0
MSR 0x482: 0xfff9fffe 0x0401e172
MSR 0x48b: 0x000003fb 0x00000000
MSR 0x48c: 0x00000f01 0x04114040

since you mention this is a possible bug with KVM is there some useful information i can relay to my ISP (they are a BSD friendly vendor) that they can try on their end as a workaround, or perhaps something they ping the linux/kvm community about?

 As above, this isn't the issue for this particular case: it manifests as a hypervisor guest immediately exiting when started.


ok perfect this aligns with what i'm seeing as well when i run bhyvload or bhyvectl and it just bails with a "vm_create: Device not configured" error.

Cheers,
