I am running VirtualBox VM 7.0.12 r159484 darwin.amd64 (Oct 12 2023 20:27:35) on Intel Mac Mini:

Model Name: Mac mini
Model Identifier: Macmini8,1
Processor Name: 6-Core Intel Core i5
Processor Speed: 3 GHz
Number of Processors: 1
Total Number of Cores: 6
L2 Cache (per Core): 256 KB
L3 Cache: 9 MB
Memory: 8 GB
System Firmware Version: 1968.140.7.0.0 (iBridge: 20.16.6072.0.0,0)
OS Loader Version: 577.140.2~15

VirtualBox does not detect CPU virtualization extensions (VT-x) and the guest (32-bit Win XP) runs terribly slow.

I think this is the relevant part of VBox.log:

My OS is:

ProductName:            macOS
ProductVersion:         13.5.2
BuildVersion:           22G91

The CPU of course supports virtualization:

sysctl -a | grep machdep.cpu.features
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 FMA CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC MOVBE POPCNT AES PCID XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C

Virtualization is of course enabled in the machine (showvminfo):

Hardware Virtualization:     enabled
Nested Paging:               enabled
Large Pages:                 enabled
VT-x VPID:                   enabled
VT-x Unrestricted Exec.:     enabled
AMD-V Virt. Vmsave/Vmload:   enabled
IOMMU:                       None
Paravirt. Provider:          Default
Effective Paravirt. Prov.:   None

How can I fix/enable hardware virtualization on my Mac?

I assume you installed the VirtualBox 7.0.12 Oracle VM VirtualBox Extension Pack on the Ventura host and Guest Additions CD on the Windows XP guest.

According to Oracle, macOS Ventura is not supported as a host OS when using VirtualBox 7.0.12. Ventura was released October 24, 2022 and VirtualBox 7.0.12 was released October 17, 2023.

You might consider trying the current VMware Fusion Player 13, which supports "any Mac that officially supports macOS 12 Monterey or later". WMware offers a free VMware Fusion Player – Personal Use License.

You can have the VirtualBox and Fusion Player installed on your Mac at the same time.
