lots of APIC_TMICT exit on VM with assigned NIC

[sheng qiu]

Hi all,

i saw lots of APIC_TMICT exits while running a linux guest with
assigned NIC. The APIC_TMICT exits is only a little fewer than the
number of injected interrupts while handling network traffic on the
assigned NIC.
The network traffic was generated by running netperf on another
machine targeted at the VM.

Is this normal? if not, what kind of problem may cause it?

Thanks,
Sheng
