[rhelv6-list] Kernel errors under kvm guest using e1000

[carlopmart]

Hi all,

  I have installed a kvm guest as a Generic Linux 2.6 kernel (it is a 
Debian like distro, but it doesn't supports virtio drivers) with seven 
network interfaces (using e1000 model). After boot, guests returns me 
several errors like dmesg shows:

  ... and continues ...

  Host is a RHEL6 fully patched.

  Is this a bug when e1000 driver is used ??

Thanks.
