Bug detailed description:
--------------------------
I try to boot more than 10 guests and each guest with a VF assigned. I found it
always show erros when booting the 3rd/4th guest, but guest still create
successfully. After guest boot up, there have no VF in guest. It works fine
with xm.

Reproduce steps:
----------------
1.Prepare config file
2.Create the guest with one NIC assigned continuously.
3.We seen error information when created the third guest and guest showed white
screen.

Current result:
----------------
Fail to create guest 

Expected result:
----------------
Create guest successfully

(-) [reply] ------- Sorry, It Should be created the guest with one NIC(vf NIC ,
pci or
pcie NIC) assigned continuously in the "bug detailed description",rather than
"vif NIC". It was my fault for writing.


For this issue, sometimes I found that it showed different error information
from the attachment "error.log" as following:
