syz-manager: prints unuseful messages about broken seeds

[peiwithhao]

TL;DR

In the process of testing syz-manager locally, the target machine is linux/amd64, but the error message shows that there is no arm class system call instruction, which is very strange.

here is my cfg:

{
        "target": "linux/amd64",
        "http": "127.0.0.1:56741",
        "workdir": "/home/peiwithhao/repo/syzkaller/workdir",
        "kernel_obj": "/home/peiwithhao/Kernel/kernel_source/linux-6.7.4/",
        "image": "/home/peiwithhao/build/image/bullseye.img",
        "sshkey": "/home/peiwithhao/build/image/bullseye.id_rsa",
        "syzkaller": "/home/peiwithhao/repo/syzkaller",
        "enable_syscalls":["open","ioctl","write", "pipe"],
        "procs": 4,
        "type": "qemu",
        "vm": {
                "count": 16,
                "kernel": "/home/peiwithhao/build/image/bzImage",
                "cpu": 3,
                "mem": 2048,
                "qemu_args":"-enable-kvm"
        }
}

• go: go version go1.23.3 linux/amd64
• kernel : 6.12.1-arch1-1
• syzkaller: latest

and then the website shows the fuzzer program has not been started...

most of the stuff in the dashboard are zero!!

Let's remove these messages to not confuse users.

[peiwithhao]

But as of now, when I try to use syzkaller, although I start the vm, the fuzz still does not start.

Please send an email to the mailing list with info about the problem.
The issue tracker is for actionable bugs in syzkaller itself.

The messages should be gone after #5560
