[libvirt] GenericVmConfigFault - Unable to allocate a PCI SCSI adapter. Too many PCI devices are already configured.

[Andrew Holway]

Hello,

I am trying to create virtual machines on a VMware ESXi 5.5.0
build-1331820 with Virsh 1.1.4 on Fedora 19. I see the following.

Can anyone show me where I am going wrong or perhaps suggest a more
sensible way of spawning virtual machines on ESXi with libvirt.

Thanks,

Andrew
