Indeed? I virt-manager, I don't see a second serial port. In either case, only the one showing up in the VM as ttyS0 is being used. But thanks for making me look, I discovered that the machine on the Intel host still used emulated SCSI instead of VirtIO für the main disk. I changed that. >Unless Tony jumps in with an > idea, I would try massaging either the good or bad VM's QEMU > invocation, e.g. see if you can get the AMD VM to "pass" by pulling in > stuff from the Intel VM, or get the Intel VM to fail by making its > command line look more like the AMD VM. In Virt-Manager, both machines don't look THAT different tbh. I verified the XML and the differences are not big at all. Do you want me to try different vCPU types? Currently the VM is set to "Opteron_G3", would you recommend a different vCPU for the host having a "AMD GX-412TC SOC" host CPU?
