Re: [Astlinux-users] No eth0 after upgrading Astlinux

[Lonnie A. <li...@lo...>]

Hi Gerard,

AstLinux Hyper-V support [1] needs a Board Type of "genx86_64-vm", so check by typing "cat /proc/cmdline" in the CLI and look for the string " astlinux=genx86_64-vm " as that is what you want.  If you only have the string " astlinux=genx86_64 " then that is the issue.

The (non-VM) Board Type of "genx86_64" may have been able to run Hyper-V at some point, you really need a Board Type of "genx86_64-vm".  The VM version has specific hv_netvsc and hv_utils modules that support Hyper-V virtual IO drivers.

Note, your upgrade did not change the board type, so you can test the above with the old astlinux-1.3.8 version.

Let us know if this is the issue, before any more diagnosis.

Luckily, this AstLinux is running on a virtual machine under Windows Hyper-V, and I can access it using the Hyper-V manager. I can login with the root user, and should be able to enter commands. If anyone can help me with the Linux commands to restore this box to its previous version before the upgrade, that would be great!
