| "summary": "The error OSProvisioningTimedOut may be caused by either a VM boot issue or a network connectivity problem. From the serial console log, although the message \"Device sda1 not found\" appears, the VM has successfully booted. This is evidenced by the line \"Filesystem at /dev/mapper/root is mounted on /\" which confirms that the root filesystem was mounted correctly. Additionally, the presence of \"localhost login:\" at the end of the log indicates that the system has reached the login prompt, confirming a successful boot. However, the log also shows \"eth0: fe80::6245:bdff:fee8:caba\" which is an IPv6 link-local address. The absence of an IPv4 address suggests that the VM may have failed to obtain an IP via DHCP. This could prevent the VM from communicating with the Azure platform, including accessing the WireServer (168.63.129.16), which is essential for provisioning. Therefore, the lack of IPv4 connectivity is a likely root cause of the OSProvisioningTimedOut error.", |

There was a problem hiding this comment.
The keywords and issue still mention /dev/sda1, but the summary focuses on IPv4, which seems inconsistent. How was it determined that the problem is related to IPv4 rather than a missing root disk?
