I am attempting to install OpenStack DevStack on an LXC guest machine. One of DevStack's packages requires a new kernel module, but when I try to run modprobe on the LXC guest I get an error:
ubuntu@lxc$ sudo modprobe scsi_transport_iscsi
FATAL: Could not load /lib/modules/3.2.0-48-generic/modules.dep: No such file or directory
How can I install this module for my LXC guest machine?
I see a lot of charms with both a relation-changed and a relation-joined hook for their relations. Sometimes the two hooks are even the same file, with one being a symlink to the other. However, the juju docs say that both the relation-joined and relation-changed hooks run when a relation is joined.
Should my charm include only one hook or the other, not both?
The Unity Dash and HUD are slow to open, sometimes freezing the system for up to four seconds when I first hit the Alt or Super keys. Is there a simple way to find out where the time is going?
The folks in #ubuntu-unity advised that I could run valgrind --tool=callgrind compiz --replace to generate a profile of the application, however I want a simpler place from which to start troubleshooting.
NetworkManager is showing a number of different wireless networks available in my neighbourhood. I would like to know what channels the other wireless networks are operating on. How can I view these wireless network's channel information?
I am aware of the iwlist scan command but it does not see most of the networks that NetworkManager sees: the networks shown by running sudo iwlist wlan0 scan are completely different from NetworkManager's list.
I would like to use Empathy for Internet voice chat, but I do not see an option under the Empathy Accounts menu to create a SIP account.
How do I set up Internet voice calling in Empathy?
