Hi everybody,

Attracted by the puppies, I'm trying to run lhype. The patch applies cleanly
to 2.6.20-rc2, my .config is in accord with lhype.txt, but when I try to
launch an instance, I get this:

$ sudo drivers/lhype/lhype_add 64m 0 vmlinux --tunnet=192.168.19.1 --block=linux.img root=/dev/lhba
lhype_add: Failed to get DMA buffer from 0xb7fff008: No such file or directory
lhype_add: network: no dma buffer!: No such file or directory
lhype_add: Running guest failed: No such file or directory

When I subsequently retry, I get the same, but third and following tries
only give:

lhype_add: Running guest failed: No such file or directory

$ dmesg | tail
lhype: mapped hypervisor at ffc00000
(...)
Guest didn't handle trap 6 at c071b594 (cr2=00000000,err=0)
Guest 0 dead drivers/lhype/init.c:424

$ file linux.img
linux.img: x86 boot sector, LInux i386 boot LOader

$ file vmlinux
vmlinux: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, not stripped

Any clues? I think I've followed lhype.txt to the letter.

Thanks!
