Hi,
I am getting the following error while trying to install mininet (output
below).
The whole problem started after I tried to install openvswitch according
to the tutorial at
http://docs.openvswitch.org/en/latest/intro/install/general/ hoping to
get the userspace switch to work.
I retried the installation procedure using
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc
and also starting the ovsdb-server with different paths provided via the
--remote and --unixctl options.
The ideal outcome would be if I could simply run mininet with --switch
ovsk and --switch user again. I realize that the mininet installation
fails due to
/var/run/openvswitch/ovsdb-server.4301.ctl" (No such file or directory)
not being found. A similar file is created for one reason or another,
but with the wrong pid in its name:
kurt@kurt-UX305LA:~$ ls /var/run/openvswitch/
ovsdb-server.2493.ctl ovs-vswitchd.26682.ctl ovs-vswitchd.9499.ctl
ovs-vswitchd.pid
kurt@kurt-UX305LA:~$ ls /usr/local/var/run/openvswitch/
ovsdb-server.pid ovs-vswitchd.pid sock.db
Any help would be much appreciated.
Best,
Daniel
