Let me go through the details step by step. + +The user reports that when their laptop isn't connected to a network (like Wi-Fi), running `qemu-img info` with an NBD driver pointing to ::1 fails. The error says "address resolution failed for ::1:1234: Address family for hostname not supported." However, if they use 'localhost6' instead of '::1', it works. They can ping6 ::1 fine, so the IPv6 loopback is functioning. + +First, I need to understand what's happening here. The command uses `file.host=::1`, which should connect to a local NBD server on port 1234. When there's no network connection, this fails with an address resolution error instead of just saying "Connection refused," which would indicate that the server isn't listening. + +I recall that in networking, '::1' is the IPv6 loopback address, equivalent to 'localhost'. The fact that it works when replaced with 'localhost6' suggests a possible issue with how the hostname is resolved or handled. + +Now, considering whether this is a user-mode or system-mode problem. User-mode issues typically involve application-level problems, while system-mode relates to kernel-level services like networking stacks, device drivers, etc. + +In this case, the problem seems related to address resolution and socket connections, which are managed by the operating system's networking subsystem. The error message mentions getaddrinfo/glibc, which are part of the C library used for network operations. However, since the issue only occurs when there's no network connection, it might be how the system handles IPv6 in offline modes. + +The user also mentioned that /etc/hosts includes both IPv4 and IPv6 localhost entries, so that shouldn't be the problem. The fact that ping6 works indicates the kernel's IPv6 stack is functioning correctly. + +But why does `qemu-img` fail to resolve ::1 when there's no network? Maybe without a network connection, certain DNS or resolver settings change, affecting how getaddrinfo behaves. Alternatively, the absence of a default route might cause issues in resolving local addresses over IPv6. + +Since this involves socket connections and address resolution at a low level, it seems more like a system-mode issue because it's interacting with the kernel's network stack rather than an application-level bug within qemu itself. The fact that replacing ::1 with localhost6 works suggests that the hostname lookup is succeeding where the IP address isn't, possibly due to how the resolver handles names in offline situations. + +Therefore, this bug is likely related to system-mode components. +</think> + +system \ No newline at end of file |
