[libvirt] [PATCH 0/8] Various KVM PCI device assignment improvements

[Mirko Raasch]

Hi,

thanks for you improvements.

I updated libvirt with git and tried to passthrough two pci devices to a 
linux guest.

 <hostdev mode='subsystem' type='pci' managed='yes'>
      <source>
        <address domain='0x0000' bus='0x05' slot='0x01' function='0x0'/>
      </source>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <source>
        <address domain='0x0000' bus='0x05' slot='0x03' function='0x0'/>
      </source>
    </hostdev>

In the guest, only one of them works and after the shutdown of the 
guest, i got a segfault on the host.

libvirtd[15363]: segfault at 38 ip 0000000000421164 sp 00007fff59d1dfb0 
error 4 in libvirtd[400000+6d000]

I use kernel 2.6.30-4 on the host.

What did i wrong?

Greetings
