Hi, I create a VM with a virtual pci device "-net nic,model=e1000", and I attemped to read/write the bar0 of the virtual nic inside the guest userspace by mmap the "/sys/bus/pci/devices/xxxx:xx:xx.x/resource0" to the userspace. What I expected is a VMEXIT should occur when I read/write the bar but I didn't see any VMEXIT event. So I'm confused with this and any detailed analysis about mmio handle routine would be appreciated.
Thanks
