Re: Another NVMM question
No, this is an old Windows-95C that I’m trying to install under NVMM. It did install and run under XEN and I tried using the same parameters in NVMM. Had to specify no more than 768Meg of RAM, Pentium class CPU and VCPU=1 (which I assume would be SMP 1). So I suspect it’s either a bug or a missing feature in NVMM. I can’t try Windows 10/64 (or 32) as I don’t have a license or CD for it. On Oct 9, 2019, at 11:15 AM, Chavdar Ivanov wrote: > Any chance you are trying to install Windows 10/64 ?

Re: Another NVMM question
Windows 95 is unsupported by qemu at least in the softemu mode. I don't know whether it could work with NVMM.

Re: Another NVMM question
Any chance you are trying to install Windows 10/64 ? AFAIK it still doesn't run with nvmm. The 32-bit version is fine. though.

Another NVMM question
Got a few systems installed and running under NVMM in NetBSD 9.0, but ran into this playing with a Windows installation. It appears to be coming from NVMM and I’m curious if this is a current limitation in NVMM or are there some QEMU parameters which can be used to circumvent this. NetBSD Virtual Machine Monitor accelerator is operational qemu-system-x86_64: NVMM: Mem Assist Failed [gpa=0xb8040] qemu-system-x86_64: NVMM: Failed to execute a VCPU.
