VMware 5.1 passthrough problem

[powadha]

I've setup a VM with an AMD Radeon HD6570 on passthrough. I know this is all not supported by VMware but.....still trying

With hdmi over ethernet the idea is to build a vm that will replace my media center (just a sweet home lab project http://www.atlona.com/625-HDMI)

Now I've read a lot of problems on passthrough on 5.1 (latest) where 5.0 seemed to be fine. I'm running 5.1 latest and should be happy with getting a stable system anyways but...

The only way to run the VM is on 2GB memory.

As soon as I raise the memory to 4GB or more the VM wont boot. I dont see a direct link to passthrough and the amount of memory on the VM but apparently there is.

Is there anyway to raise the amount of memory with the VM booting up normally?

Hi...

Do u mean that the machine isn't starting up at all..or it's powered on but the boot doesn't finish...??

In the case of not starting up at all..and according to the following link (Note section before additional info):

All memory of the VM must be reserved..i.e. if ur VM will have 2 GB of RAM..they must be reserved on the host.. which means that the host must have 3GB of RAM + (2GB reserved + 1 GB for host itself).

VMware KB:     Configuring VMDirectPath I/O pass-through devices on an ESX/ESXi host

Memory is reserved, so that isn't the problem unfortunately....It powers on until 95% stays at that point for a while, goes to 100%, and dies.......

You need to configure the pcihole paremeter in the vmx-file, look at this thread:

VMDirectPath and ATI Radeon
