<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a custom PCI data acquisition card for which I only have Windows XP drivers, so I’m running WinXP in a QEMU-KVM VM under CentOS 7. I have PCI passthrough working fine. (I added the PCI card to the VM with virt-manager) However, the
VM will not autostart on boot of the host machine. I have the following output in /var/log/libvirt/qemu/win_xp.log:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Again, this only happens at boot when the VM should be auto-starting. I can start it just fine manually with virsh or virt-manager. Perhaps the issue has to do with libvirtd starting too soon? N.b. I’m new to messing with init systems in
general, systemd in particular.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help would be greatly appreciated. I haven’t had any responses from the libvirt-users list, the CentOS forums, or my local university Linux mailing list.<o:p></o:p></p>
