Thanks Jason. I found your post already, but I can't boot an old kernel.
That was my biggest problem. ;-)

Kernel 5.9 and 6.4 (2.6.32-358) has proper built in support for Hyper-V
All you need to do is:
Boot into the old kernel
Remove the old Hyper-V components as follows:
Execute the following steps in the bash shell.
1. First, execute:
rpm qa | grep microsoft
Example:
On a RHEL 5.8 system, you will see the following:
# rpm qa | grep microsoft
kmod-microsoft-hyper-v-3.4-1.20120727
microsoft-hyper-v-3.4.20120727
2. Next, execute:
rpm e microsoft-hyper-v-<version string from step 1>
kmod-microsoft-hyper-v-<version string from step 1>
Then reboot into the new kernel 2.6.32-358
You can then add a NON-LEGACY network card and have a much faster network
stack. Give the new card the same Virtual MAC as the old card and there are no
config changes needed either

Subject: [BlueOnyx:12643] Urgent Hyper-V problem - please help :-)
Hello,
I did a yum update on a customers server and after that there is no network
connection.
I read all the issues with hyper-v and sometime ago Michael noticed a problem
with irqbalancing on this server. But this time "service irqbalancing stop" did
not change anything.
All solutions point me to boot an older kernel, but I can't do this. Everytime
I boot the machine, it allways go to the last kernel and changing the grub.conf
only results in a broken server, which won't boot anymore.
Does anyone has an idea for me? I can boot the server in kernel
2.6.32-279.5.1.el6.i686.
Thanks in advance.
Lars.
