*SOLVED* IRQ Interrupt Storm
*SOLVED*
So my current setup is as follows:
ESXi
--> FreeBSD(ZFSGuru custom distro) running in the hypervisor with 2xIntel SASUC8i controllers passed through directly to the guest
Now my issue is a huge wave of "interrupt storm detected on IRQ 18/19, throttling source". Ran vmstat -i and it shows that IRQ 18/19 are my two controllers, identified as mpt0 and mpt1.
Any solutions or clues on how I can solve this problem? Is there anyone else who has successfully passed one of these controllers through to a FreeBSD guest?
Edit: I should note that I tried doing a vanilla install of FreeBSD just to compare and yes, the issue is present there as well. The issue however does NOT crop up when booting into FreeBSD bare metal, only when in a VM.
Edit: It was an IRQ conflict, both the NIC and the controller share IRQ 19, if anyone knows how I can change this please let me know, I'm still a little unsure how to go about changing it now that my problem is locked down
