PCI passthrough with PV-183

[redninjas101]

[FONT=&amp]I’m attempting to install zoneminder on a vm in Proxmox 2.1. I’ll have to apologize in advance, because I’m new to Proxmox. My host hardware is as follows:[/FONT]

[FONT=&amp]Mobo: Giga-byte GA-EP43-UD3L[/FONT]
[FONT=&amp]CPU: Intel Q9400[/FONT]
[FONT=&amp]RAM: 6 Gb OCZ DDR2[/FONT]
[FONT=&amp]HDD: Seagate 2 Tb[/FONT]
[FONT=&amp]Capture Card: Pro Video PV-183 8 video/8 audio inputs[/FONT]

[FONT=&amp]The hardware is VT-d compatible and iommu turned on in the BIOS in grub.conf. When listing PCI devices using lspci –nn, I’m greeted with 16 individual devices, instead of one consolidated address to use for the ‘hostpci0: xx:xx.x’ in the vm.conf file. The output of lspci –nn is listed below.[/FONT]

[FONT=&amp]I[/FONT]’ve tried several of the devices addresses but Proxmox yields an error in the web interface when starting the VM, stating:[FONT=&amp]

[/FONT]

No IOMMU found.  Unable to assign device "hostpci0"

I get the above No IOMMU found even though the result of the command dmesg | grep -e DMAR -e IOMMU is as follows:

root@proxmox:~# dmesg | grep -e DMAR -e IOMMU
Intel-IOMMU: enabled
root@proxmox:~#

I’ve even tried to use the PCI bridge device, but I’m getting an error as follows. Has anyone got any suggestions or have a setup like this working with zoneminder?


Any help would be greatly appreciated

It appears that not all virtualization technology is created equal. Although the board I have supports VT, it appears that the P43 chipset may not support VT-d. I looked at wikipedia's list of chipsets and supported features: http://en.wikipedia.org/wiki/List_of_Intel_chipsets

Well I guess that's as good of an excuse as any to upgrade...

I apologize for bumping an old thread, especially with my first post, but I have the exact same situation. Were you able to get this working after upgrading? I've been unable to pass my Bt878 card through to my ZM VM and have tried the same thing as you. I don't receive any errors about IOMMU, and it is enabled. I'm even able to assign 2 different address to hostpci0 and hostpci1, the VM starts but there are no new devices listed.
