[one-users] Database problem with oZones server

Fri Nov 18 02:06:53 PST 2011

That's right. It was a permissions problem. I had tried to run the ozones
server as oneadmin before asking for help, but it did not work. The actual
problem was that I had run the server the very first time as root, and so
root became the owner of the log file, giving problems when running the
server as oneadmin later on. I remove the log file, started the server as
oneadmin and everything worked. Thanks!

Cheers,
Humberto

Hello,

There are two ways of installing OpenVSwitch: with kernel modification; and
without it (userspace mode). I was thinking about installing the userspace
mode?is there any problem? Is there any difference in terms of Opennebula?s
interaction with OVS?

Cheers,

Jo?o
