Hello. I faced the same issue with qemu, nvmm and freedos. Tried to debug with no luck. I found a workaround - run qemu with no acceleration, install freedos, then run it with acceleration turned on. This issue only happens when is it is being installed.
Hello,
I tried to install FreeDOS under Qemu in NetBSD 10.1 using nvmm
acceleration driver.
I get an error like this when almost installed on the virtual disk:
qemu-system-i386: NVMM: Unexpected VM exit code 0xffffffffffffffff [hw=0x9]
qemu-system-i386: NVMM: Failed to execute a VCPU.
[1] Abort trap (core dumped) qemu-system-i386 -m 64 -accel nvmm -smp 1
-dri...
I removed nvmm acceleration and I was able to end the installation
without acceleration but it was painly slow.
I have been able to virtualize a full Debian GNU/Linux system using
nvmm, no problems at all. Why nvmm fails with FreeDOS?
Thanks so much.
Ramiro.
