Hello.

After updating from http://svn.freebsd.org/base/projects/bhyve to
http://svn.freebsd.org/base/head i cannot use vtnet device inside bhyve
guests, both 10 and 9 freebsd.

I`m getting these errors at boot, and no vtnet device:

guest 9.1-RELEASE + virtio
virtio_pci0: cannot allocate interrupts
vtnet0: cannot allocate virtqueues
(guest system boots, but no vtnet device)

guest 10.0-CURRENT
virtio_pci0: <VirtIO PCI Network adapter> port 0x2000-0x201f mem
0x40000000-0x40001fff at device 1.0 on pci0
vtnet0: <VirtIO Networking Adapter> on virtio_pci0
virtio_pci0: host features: 0x18020 <Status,MrgRxBuf,MacAddress>
virtio_pci0: negotiated features: 0x18020 <Status,MrgRxBuf,MacAddress>
vtnet0: Ethernet address: 00:a0:98:e0:a7:44
virtio_pci0: exhausted all interrupt allocation attempts
vtnet0: cannot setup virtqueue interrupts
(guest system hangs)

How to fix these errors?

Thanks.
