Hi, Unfortunately, after I tried almost all methods, the network still cannot be connected. But I can be sure that the ivshmem-net device did not receive the interrupt, but the shadow device that also uses the ivshmem interface can receive the interrupt normally, and the state change of another virtual device is detected. I want to know if this is due to the kernel version. Are there any kernel branches that you maintain yourself? Best wish 在2021年12月27日星期一 UTC+8 19:49:29<Florian Bezdeka> 写道：
