Subject Cloudstack agent keeps rebooting kvm host..
Date Fri, 22 Jun 2012 16:22:16 GMT
Hi,

  The saga continues!  I added a KVM host.  The agent decided it wants to
constantly reboot the server:

Broadcast message from root@kvm1.xxxxx.xxxx

The system is going down for reboot NOW!

It looks like the agent was in fact, at least able to create the initial
directory:

[root@kvm1 ~]# ls -al /mnt/9c2be815-de2b-3c14-84bb-54025d782794
total 8
drwxrwxrwx  2 root root 4096 Jun 22 23:58 .
drwxr-xr-x. 4 root root 4096 Jun 22 23:58 ..

Here's the agent properties file:

#Storage

guest.network.device=cloudbr0

private.network.device=cloudbr0

First time I'm seeing this error...  Last time my kvm setup went well, but
KVM was my first hypervisor, now it's the second.

Thanks!
Alex
