[ovirt-devel] OST: libvirt: error : internal error: Check the host setup: enabling IPv6 forwarding with RA routes

[Milan Zamazal]

Hi, I get the following error when I try to run OST, I think since I've
upgraded my computer to RHEL 7.4 recently:

  + lago start
  @ Start Prefix: 
    # Start nets: 
      * Create network lago-basic-suite-master-net-storage: 
  libvirt:  error : internal error: Check the host setup: enabling IPv6 forwarding with RA routes without accept_ra set to 2 is likely to cause routes loss. Interfaces to look at: enp0s25
      * Create network lago-basic-suite-master-net-storage: ERROR (in 0:00:00)
    # Start nets: ERROR (in 0:00:00)
  @ Start Prefix: ERROR (in 0:00:00)
  Error occured, aborting
  Traceback (most recent call last):

      if ret is None:raise libvirtError('virNetworkCreateXML() failed', conn=self)
  libvirtError: internal error: Check the host setup: enabling IPv6 forwarding with RA routes without accept_ra set to 2 is likely to cause routes loss. Interfaces to look at: enp0s25

Do you have any idea how to fix / work around that and make OST running
again?

(Complete lago.log attached.)

Thanks,
Milan
