Xenserver Issues

Some times things go a bit astray like the local hard dive fills up with log files.

Once you clean them out you might still not beable to get access to the server via Xencenter

Try going to the local shell of the server and type

[root@xenserver2 ~]# xe-toolstack-restart

Stopping xapi: Lost connection to the server.
. [ OK ]
Stopping the v6 licensing daemon: [ OK ]
Stopping the memory ballooning daemon: [FAILED]
Stopping perfmon: [FAILED]
Stopping the fork/exec daemon: [ OK ]
Starting the fork/exec daemon: [ OK ]
Starting perfmon: [ OK ]
Starting the memory ballooning daemon: [ OK ]
Starting the v6 licensing daemon: [ OK ]
Starting xapi: …start-of-day complete. [ OK ]
[root@xenserver2 ~]# xe-toolstack-restart

After that it all looks good. Its a good idea to find out what went wrong so you can fix that and not just use this command every day.

Easy way to add DNS server to Centos 6

The minimal install of Centos 6.2 is exactly that. Very minimal while this is good for appliances if you dont know your way around linux and vi it could be a bit hard to get a network connection going.

Here are a few tips i have picked up.

Setup a IP address on a nic

ifconfig eth0 netmask up
this will add a default gateway
route add default gw
These settings will be removed from the server on reboot. 
Run this to make the nic come up on boot automatically.
# cd /etc/sysconfig/network-scripts/ 
# sed -i -e 's@^ONBOOT="no@ONBOOT="yes@' ifcfg-eth0

To put a dns server in try

echo “nameserver” > /etc/resolv.conf

This adds the google dns server to the resolv.conf file and your ready to go.

If you want to use a GUI to setup a perminate IP address try

yum install system-config-network-tui

then system-config-network-tui
