Re: [ovirt-users] Failed to check for available updates on host * with message 'Command returned failure code 1 during SSH session 'root@*

Yesterday I changed the settings the host to: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 I deleted the last two lines in /etc/sysctl.conf and rebooted host.
