Hi all!


I've a cluster (active/passive) with two KVM VM with Asterisk and 
Pacemaker+Corosync. I wonder if anyone tried to use a OpenVox A400P 
card from a virtual machine.

My idea is to have both nodes accessing this card. I don't know if it is
possible, I wish that in this scenario when a node is accessing the
card, the other don't use it.

Of course this is a scenario for testing, but I wonder if I can do
this kind of configuration on the cluster over virtual machines.

Hardware:
Motherboard: ASUS M2N32-SLI DELUXE ACPI BIOS Revision 0706
Processor:   AMD Athlon(tm) 64 X2 Dual Core Processor 3800+

The hardware seems to support IOMMU, but it is not enabled:

# dmesg | grep -i iommu
[    0.000000] Please enable the IOMMU option in the BIOS setup
[    0.654618] PCI-DMA: using GART IOMMU.
[    0.654623] PCI-DMA: Reserving 64MB of IOMMU area in the AGP aperture


Software versions:

# uname -a
Linux ss01 2.6.39-bpo.2-amd64 #1 SMP Thu Aug 4 11:42:06 UTC 2011 x86_64 GNU/Linux

Thanks in advance for your reply.


Regards,
Daniel
