According to your config, 1:0:0.0 ist the first ivshmem device, 1:0:1.0
is the second one, right?
Could you please try to enable one ivshmem device, so please disable the
second one for testing. Let's try to get one running, then we can go
further.
And for the first ivshmem device, would you consider (just for testing),
to only connect two peers? And, in your config, plase use the
JAILHOUSE_SHMEM_… macros for defining the ivshmem memregions.
Thanks,
Ralf
