Hello, For experimental purposes, I would like to use 1 core to establish communication between host and guest. The idea is to maintain a communication from host to guest permanently.
using multiple vcpu in a multicore machine (x86-64) 1)guest side sends a VMEXIT call (.byte 0xf,0x1,0xc1) 2) VMM receives the message but wait until a condition is accomplished 3)VMM return the answer 4)guest receives and immediately repeat 1) When I try it, VM freezes until VMM returns. I was thinking that this behavior was due to qemu_mutex so In VMM, before run the function that returns the message, I unlocked the mutex and after the return locked again... no effect. Could you please suggest me in what direction to go?
