I have a PCI sound card that I would like to assign to a VM, but
when I try to do so the VM fails to start and displays this message:
Error starting domain: Unable to read from monitor: Connection reset

The sound card is an Asus Xonar DGX PCIe 5.1, and identifies itself
as "07:04.0 Multimedia audio controller: C-Media Electronics Inc CMI8788
[Oxygen HD Audio]".
I see the same problem if I try to assign the motherboard's Intel
Xeon E3-1200 HD Audio Controller to the VM. Both of these devices
are supported by the host kernel (3.18.17-13.el6.x86_64).
I have no problem assigning a USB sound device, but those have very
limited capability.
Which hypervisor / CentOS version are you using?
libvirt-0.10.2-54.el6.x86_64 in CentOS 6.7,
using kernel-3.18.17-13.el6.x86_64 from the Xen4CentOS 6 repo.
(I need that kernel for the motherboard's sound controller. The
behavior when trying to assign a PCI device to the VM is the
same with the standard 2.6.32 kernel in CentOS 6.7.)
That's qemu / KVM.
