Kernel 5.12.12-300 breaks host resolution
https://bugzilla.redhat.com/show_bug.cgi?id=1976371
Very weird that the kernel could break name resolution since that
all works at library level. Maybe some "deprecated" interface
is being used by 99% of the lookup code, and they got rid of
it completely in the new kernel?

What I find equally weird is that in the BZ he states that his qemu VM's are working just fine. If the VM's are working and they have been updated to the same kernel then what would
be the difference?  A proxy setting perhaps?

More funny!  The VM's are using my caching name server
ON MY HOST !!!!


Sure, that's pretty much the default if your VM's are using DHCP.

The one thing to recall is, and this is from memory, is that "host" and "dig" don't make use of the system's resolver library.  They query dns servers directly. So, another thing to check is if the
/etc/nsswitch.conf on the VM's are the same as the host.



Dig did not work either.

function GetPublicIP () {
    local WIP=$(dig +short myip.opendns.com @resolver1.opendns.com)
    # echo "WIP = <$WIP>" > "/dev/tty"
    if [[ "$WIP" == *"not found"* || "$WIP" == *"no servers could be reached"* ]]; then
       WIP="Not Found"
    fi

    echo $WIP
}

I don't know were that snippet comes from.  But, the "Not found" may be due to dig using the system's resolver to first get the IP of resolver1.opendns.com.  So, I would have used the IP of that instead.

I would still check the nsswitch.conf files.



My computer is functioning perfect under the prior kernel.

I am not sure why you want the /etc/nsswitch.conf, but
it is anyway.  Kernels should not affect it.
