CorePure64 v17 networking issues

[tzx17077]

Hi all,

I am running TinyCore guest VMs in different hypervisors, such as VMW, Virtualbox, Hyper-V.
All of those use the 64bit port w/o graphical desktop (CorePure64).
With the latest version I face issues with my virtual network switches for Hyper-V supervisor: TinyCore does not detect them as network cards and thus refuses to go „online“.
VMWare and Virtualbox on the other hand work fine.

Anyone else facing similiar issues with Hyper-V? Does the kernel lack the capability to support Hyper-V networking? It so, why was this not the case with the previous versions?

Hi tzx17077
I just took a look at the TC16 and 17 x86_64 config files and noticed a
bunch of  HYPERV  options visible in TC16 but missing in TC17.

This one stood out. Does this look like what's missing:
http://tinycorelinux.net/16.x/x86_64/release/src/kernel/config-6.12.11-tinycore64

Code: [Select]

#
# Microsoft Hyper-V guest support
#
CONFIG_HYPERV=m
# CONFIG_HYPERV_VTL_MODE is not set
CONFIG_HYPERV_TIMER=y
CONFIG_HYPERV_UTILS=m
CONFIG_HYPERV_BALLOON=m
# end of Microsoft Hyper-V guest support
http://tinycorelinux.net/17.x/x86_64/release/src/kernel/config-6.18.2-tinycore64

Code: [Select]

#
# Microsoft Hyper-V guest support
#
# CONFIG_HYPERV is not set
# end of Microsoft Hyper-V guest support
Here are all of the  HYPERV  entries for both config files.
TC16:

Code: [Select]

tc@E310:~/Desktop$ grep HYPERV config-6.12.11-tinycore64

TC17:

Tinycore wont recognize HyperV synthetic NIC and is apparently missing modules to recognize HyperV synthetic NICs. we highly use TCL has a router but being only able to use legacy NIC is quite problematic.

Any help or suggestion to easily manage HyperV NIC without recompiling the kernel constantly would be appreciated

Hi bdesro
Welcome to the forum.

I merged your topic with this one because they appear to be related.

Hi, I too am facing the same issue. it seems that only legacy HyperV adapter are recognized because they dont require any drivers from the OS perspective. I tried with both version 16 and 17 and they both didnt have the proper kernel module for HyperV nor the packages available for installation.... I'm trying to figure a proper alternative to recompiling the kernel because legacy NIC in hyperV are limited to 100mbps....

[tzx17077]

So can anyone recompile kernel with all Hyper-V modules? If not, where can I find instructions on how to do it myself and compile a custom kernel?

[CNK]

There are instructions for building a custom kernel on the Wiki.

[tzx17077]

I keep getting errors when following the steps mentioned inside the wiki. Can someone build a custom kernel with all Hyper-V configuration settings enabled (or at least set to m).

It would help if you could show the steps you took and the errors you got
