2017-02-01 00:19:30 -0500 commented answer Packstack installation always gives error of mariadb-server being obsolete and removed by mysql-community-server which is already installed

Hi, Thanks for reply.. However, the "yum update" command started giving error in delorean-deps-newton.repo and delorean-newton.repo files after using the steps mentioned here.

I checked "ls -l /etc/yum.repos.d" and till there it was as mentioned in the link.

2017-01-31 10:23:44 -0500 asked a question Packstack installation always gives error of mariadb-server being obsolete and removed by mysql-community-server which is already installed

Hello, I am installing OpenStack mitaka (tried with Newton also) over Centos 7 using Packstack. It is a Single node installation. Have used following commands to install -

yum install -y centos-release-openstack-mitaka yum install -y openstack-packstack packstack --answer-file /root/answers.txt

But even after updating centos, reinstalling mysql many times, I am getting same error -

I have already removed mysql-community-server and tried it, installed mysql-community-server again and tried it, even uninstalled mysql-community-server and installed mariadb-server-galera (which inturn installed mysql-community-server only) but none of these worked.

Any clue/help would be appreciated.

2017-01-12 09:42:28 -0500 asked a question VM not accessible from external host through public IP and it cannot ping external gateway also

Hello,

I am using dell Poweredge server with Ubuntu 14.04.5 with OpenStack Newton release (single node installation). However whenever I create a VM on Private NW and assign a Floating IP to it (for test, created a VM with Cirros image also), I am not able to ping the VM from Dell server using the Public IP. Also from inside the VM, I am not able to ping the Public IP gateway or the Dell server. The installation is done using Devstack. Though I am able to ssh into the VM using ip netns exec dhcp of the Public network.

The LAB LAN IP is of the series 10.10.15.0/24 (used as public IP range). The Dell server has IP 10.10.15.203. Gateway is 10.10.15.2

The Private NW is- 172.16.0.0/24.

Any Help would be highly appreciated.

Ifconfig of the Dell server is -
