Install problems with LinuxMint in mvmm

[Robert Nestor <rnestor%mac.com@localhost>]

Playing with nvmm in an Oct 9 NetBSD 9.0 build.  Sucessfully installed
a version of NetBSD 8.0 but ran into problems tryuing to install a
LinuxMint 19.2 64-bit system.  Nvmm throws these errors:

And the Linux installer panics.

Qemu was invoked with:

qemu-system-x86_64 -m 256 -accel nvmm -cdrom /home/linuxmint-19.2-xfce-64bit.iso -name "LinuxMint-19.2 Install" -smp 2 -netdev tap,id=nd0,ifname=tap0,script=no,downscript=no -device rtl8139,netdev=nd0 -drive file=/home/LinuxMint-19.2.dsk,media=disk,format=raw 

Any ideas, or am I missing some important qmeu option here?  NetBSD runs fine with this set of options in qemu.
