Re: No 'PCI' bus found for device 'ivshmem-plain'

cpu we are using cortex-a57 because it is nearby to our actual hardware exynos v9

Hi,

our kernel is build with aarch64le. it is 64 bit ARM architecture.

when i am trying to use virt as machine, then qemu isn't starting. it is being stuck after entering command,

If it is, then it must be a 32-bit kernel. So trying to run it
on the cortex-a57 will not work at all, because that is a 64-bit
CPU and will only boot 64-bit kernels. (QEMU emulation does not
allow booting a guest kernel in 32-bit mode for CPUs that in
hardware support both 32-bit and 64-bit, I'm afraid.)

I just did: try the "virt" board. You'll need to decide what
CPU you actually want to run first, though.
