Subject RE: Network Problems from within SSVM
Date Tue, 30 Apr 2013 13:35:59 GMT
Can you ping your gateway, 192.168.122.2? Are there any iptables rules on the mgmt server?
And are your exports set up correctly on 192.168.122.130? How about if you downed some on
the interfaces on the SSVM and then tried to ping the management server. Say ifconfig eth0
down etc.. Does any of the interfaces work if the others are all disabled?

Subject: Network Problems from within SSVM

Hi List,

we are trying to setup a Cloudstack configuration, and have it working to the point that the
SSVM is starting up and running.
The problem is, that from within the SSVM one cannot ping the management server. Which is
the reason, we think, that we are getting log entries in the management server log saying:

There is no secondary storage VM for secondary storage host nfs://192.168.122.130/export/secondary

Following some information about our configuration:

/etc/network/interfaces on SSVM:
auto lo eth0 eth1 eth2
iface lo inet loopback

iface  eth0 inet static
  address 169.254.2.31
  netmask 255.255.0.0
iface  eth1 inet static
  address 192.168.122.197
  netmask 255.255.255.0
iface  eth2 inet static
  address 192.168.122.223
  netmask 255.255.255.0

auto eth3
iface  eth3 inet static
  address 192.168.122.199
  netmask 255.255.255.0
