tested dfly on kvm? Is it possible to update, or I must use 2.10 there?
We have some known issues with 3.0 in recent versions of kvm and qemu.
They are related to the new interrupt code, I think. There are
workarounds, though!
You can start qemu/kvm with -no-acpi or set hw.ioapic_enable=0 in
/boot/loader.conf; this will let you boot. You may need to enable
polling mode for the virtual NIC as well; ifconfig em0 polling 1 will
do that.
The problem iiuc is that an interrupt is getting missed during boot,
Thank you, I will try to set hw.ioapic_enable=0. I can't change the kvm
options.
