I’m pretty confident this is proxy name resolution issues. Thanks corporate network. Disable dnsmasq in the host. (Assuming Ubuntu host) Thx, Eric Comment out dnsmasq in: $ sudo vi /etc/NetworkManager/NetworkManager.conf $ sudo systemctl daemon-reload $ sudo systemctl restart network-manager On Jun 7, 2018, at 8:20 AM, Liu, Changcheng <changcheng.liu@intel.com<mailto:changcheng.liu@intel.com>> wrote: Hi James, The issue is WAed when building centos rootfs by below changes: 1) set the proxy ip:port explicitly in rootfs.sh 2) set the dns info when staring docker daemon. Even with the above change, I still can’t build the fedora rootfs which maybe the image’s issue. Need further check.

Could you try re-running and if that doesn't work, raising an issue with the output of `sudo kata-collect-data.sh` pasted into the github issue? - https://github.com/kata-containers/osbuilder/issues/new Cheers, James _______________________________________________ kata-dev mailing list kata-dev@lists.katacontainers.io<mailto:kata-dev@lists.katacontainers.io> http://lists.katacontainers.io/cgi-bin/mailman/listinfo/kata-dev
