The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6
of the SMBIOS spec. dmidecode uses the reported version of SMBIOS to
determine the layout and what to byte-swap.
bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.

code. There are only a handful of MSRs common between the two so there isn't
too much duplicate functionality.
The VT-x code has the following types of MSRs:
- MSRs that are unconditionally saved/restored on every guest/host context
switch (e.g., MSR_GSBASE).
- MSRs that are restored to guest values on entry to vmx_run() and saved
before returning. This is an optimization for MSRs that are not used in
host kernel context (e.g., MSR_KGSBASE).
- MSRs that are emulated and every access by the guest causes a trap into
the hypervisor (e.g., MSR_IA32_MISC_ENABLE).

the minimum image size specified is always less than the maximum
image size. If makefs(1) is invoked specifying minimum image size,
but not maximum one, the program exits with an error. Example:
# sudo -E makefs -M 538968064 -B be /home/davide/disk.img $DESTDIR
makefs: `/home/davide/tftproot/mips' minsize of 538968064 rounded up
to ffs bsize of 8192 exceeds maxsize 0. Lower bsize, or round the
minimum and maximum sizes to bsize.
Assert then that minsize < maxsize iff maxsize is specified.
