Hi Community,
I am testing bhyve from FreeBSD 12.1 RELEASE.
My environment:
- CPU: AMD Ryze 3900X
- Mainboard: MSI MEG ACE X570, Default settings, latest BIOS 7C35v18
- RAM: G.Skill RipJaws V DIMM Kit 64GB, DDR4-3200, CL16-18-18-38
- GPU: Sapphire Nitro RX 5700XT
I checked the settings in the BIOS. Virtualization options are enabled.
SVM is enabled.
I follow the instruction from the FreeBSD handbook „21.7. FreeBSD as a
Host with bhyve“.
When I run
kldload vmm
I got an output that SVM is disabled by BIOS. When I check the BIOS it
is enabled.
I use bhyve on a Ryzen with an Asus Prime X470-PRO.
I wonder if your BIOS is enabling SVM but failing to update the MSR to
say it's enabled. Try commenting out the second "return (0);" in
svm_available() in sys/amd64/vmm/amd/svm.c and rebuilding the vmm
module. If SVM is actually disabled, I have no idea what impact this
change will have, so beware. If SVM is actually enabled and this hack
allows you to use it, we could probably commit a tunable to do this more
cleanly.
