Hi all,

It seems like vmm/vmd breaks in the latest snapshot:
OpenBSD 7.5-current (GENERIC.MP) #45: Thu May  2 20:53:53 MDT 2024

If I try to start vmd, I get the following:

$ doas /usr/sbin/vmd -dvf /etc/vm.conf
vmd: vmd: /dev/vmm: Operation not supported by device

Yet, it's supported according to dmesg:

$ dmesg | egrep '(VMX/EPT|SVM/RVI)'
vmm0 at mainbus0: SVM/RVI


Checking out the latest source and rebuilding the kernel manually
makes this go away though.  I haven't investigated this further but 
figured I'd drop a mail here in case someone else runs into this. :-)
