I have a machine with enough cores that I'm able to run large VMs with
up to 128 or more vCPUs.
However, it looks like bhyve's SMBIOS area is too small once we reach 65
vCPUs since I get the following assert failure on boot:
bcran@maxamd:~/bhyve % sudo ./runbhyve.sh
fbuf frame buffer base: 0xde214e00000 [sz 16777216]
Assertion failed: (curaddr - startaddr < SMBIOS_MAX_LENGTH), function
smbios_build, file /usr/src/usr.sbin/bhyve/smbiostbl.c, line 936.
Abort trap
From looking through the code it appears we can't simply make it larger
because the ACPI tables after after it.
