Why oh why do you have to dash my hopes like that. I thought my panning agony was over!
I was planning on installing ZFS-FUSE isn't that the same Ubuntu uses? I haven't used Ubuntu that much in the past. I guess now is as good as any time to learn. Are you using KVM for virt? If I went with ESXi wouldn't I have the same problems with pci pass through?

No need to answer the zfs question. I found your original question online about it.

http://zfsonlinux.org/ For Ubuntu, it is basically just adding the ppa & "apt-get install zfs". The *easiest* way to install it is to use a small ext4 /boot and /, and then mount ZFS.. Drew

Thanks Drew for all of your help. I really appreciate it. I'm hoping to install it this weekend, that is if my kids let me get away long enough.
I did get a chance to crack my box last night and didn't see anything about virtualization in the bios. So I'm assuming that I don't have AMD-V support on my motherboard. Im really bummed about that. Still going to still try my HVR-2250 and see what kind of performance I get if any. I also get my HDHR Prime today so I get to start yet another trial to see how many channels Cox provides "copy freely". Haven't found much on the internet about my area, hope no news is good news.

eurika!!
So I go through my bios one more time and come across Secure Virtual Machine (SVM) Enable/Disable under the CPU options. Nothing else is said. I look in the manual and it says the same. Did a quick google and bam http://support.amd.com/us/kbarticles...b-309-npt.aspx Secure Virtual Machine (SVM) mode, also called AMD Virtualization™ technology. So why don't they just say that in the MSI manual or BIOS??? So looks like I can do pci pass through after all. I also installed my HDHR Prime and it works great! I was able to record 3 HD channels and watch 1 at the same time without any delays or shutters. I think that is great for only having a WD Green 5400RPM (wd10eads). I can't wait until I can get my ZFS RAID 1 up and running. Now all I need is time between recordings and the kids to build out the system.

The story is that a device driver gives a device a *physical* address to DMA stuff to/from. That physical address is somewhere in computer's physical memory. Once you're running in a VM, a "physical" address is somewhat meaningless, since a guest "phyical" address is really virtualized. You also do not want to give guests access to anything but their own memory for security & stability reasons. An IOMMU is a big indirection table that translates from a "fake" physical address to a real one, on the fly. It can also reject addresses which are out-of-bounds, and from different "domains". Eg, it can disallow a device mapped into a VM from accessing another VM's ram. At one point there was a "cheesy" patchset for KVM that allowed PCI passthrough by just trusting the guest & did not require an IOMMU / VT-d setup. I'm not sure if this made it to production or not.

I was so excited. Why would you do this to me? Oh well, I still think I want to go forward with a sage vm. I don't need PCI passthrough for the HDHR Prime, and it gives me the ability to do snapshots. I also want to take advantage of ZFS. On the bright side now I have a HVR-2250 open that I can start playing with on my Ubuntu client. Maybe I will try out MythTV.
