[libvirt-users] Digium TDM410 passthrought to KVM VM trixbox

Hello, my name is Paul. I need to map a PCI device for a virtual machine. The Linux distribution is Ubuntu server 9.10, infrastructure virtualization is "KVM". The virtual machine will install trixbox. To map the PCI card is a "Digium TDM410p. There currently, KVM hosts a virtual machine that runs smoothly without any problems. In fact, this virtual machine is running Openfiler and has direct access to 2 physical disks installed on the server. Creating a new virtual machine can not connect the Digium card, directly to the virtual machine.I tried in 2 ways. 1. Directly editing the XML file for the virtual machine with the parameters indicated in the documentation: ... <devices> <hostdev mode='subsystem' type='pci'> <source> <address bus='0x01' slot='0x00' function='0x0'/> <----- this is my personal configuration </ source> </ hostdev> </ devices> ... 2. Adding the PCI card via virt-manager In both cases, the virtual machine will not start. Virt-manager returns this error: "Error starting domain/ monitor socket did not show up./ Connection refused" "Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 493, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 558, in startup self.vm.create() File "/usr/lib/python2.6/dist-packages/libvirt.py", line 293, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: monitor socket did not show up.: Connection refused" Can someone kindly help me? Thanks
