Debian :: Unable To Open A Connection To The Libvirt Management Daemon
Dec 26, 2010
I get this error message when I open up virt-manager (logged in as a typical user):
Code: Unable to open a connection to the libvirt management daemon. Libvirt URI is: qemu:///system Verify that: The 'libvirtd' daemon has been started Manually trying to start the daemon results in: Code: error : qemudWritePidFile:508 : Failed to open pid file '/var/run/libvirtd.pid' : File exists virt-manager works just fine when I log in as root.
I have Lucid Lynx with Gnome and Kernel 2.6.32 installed. Which probelms can I get if I disable Power Manager (Power management daemon) from the startup?
BTW does Code: xset -dpms s off do the same thing like disable Power Manager in the Starup Applications or DPMS is just for the Monitor?
and probably to perform other tasks requiring root privileges (?).I don't know very much about polkit, so I don't know if I'm not missing (or messing up) something.This is the error I get under 11.4:This is the expected behavior (11.3)No matter if I run Gnome, Kde or another de. The process highlighted in red on picture 2 is the one started when a user click on connecting. It fails to start on 11.4 - probably due to my own mistake (?) but I don't know. I could start virt-manager with gnomesu, kdesu or xdg-su -c, that would just start the program as root, but it shouldn't be necessary
I have been only using the free vmware server thus far for my virtualization I have recently installed Fedora 11 and am currently looking at using the XEN virtualization software. I am currently running and upgrade from F10 to Fedora 11 with the PAE kernel. Also I am using KDE 4 with kmod-nivida drivers. Now here is what I have done
To install Virtualization requirements I did the following: sudo yum groupinstall 'Virtualization'
I then also did: sudo yum install kvm qemu libvirt python-virtinst
I then installed xen: sudo yum install xen*
Now, I read that i needed "kernel-xen" but it doesn't appear to exists a "yum list kernel*' only displays kernel packages and the kernel PAE pakages so I figured I don't need it I then started all the xen services and libvirtd service Opened virt-manager and added a new connection: hupervisor: Xen and connection: local
I get the following error: Unable to open connection to hypervisor URI 'xen:///': <class 'libvirt.libvirtError'> unable to connect to 'localhost:8000': Connection refused None
I guess my question now is... what is the difference between the hypervisor: QEMU/KVM and XEN. Because I seem to be able to create a VM using this. My VM is an XP vm for work purposes to run some windows only software I would like to use XEN as I just have my mind set on it but I might just be ignorant and on the wrong track is there a how to guide for fedora 11 and xen? the fedora 7 guide i found needs the kernel-xen installed.
I have changed my web server from FTP to SFTP for security reasons. I am used to Nautilus randomly crashing, but usually I got to connect fine via FTP. Now I could connect exactly once with SFTP, but ever since I only get the useful message:Oops! Something went wrong. Unhandled error message: SSH program unexpectedly exited
I just got an error message and i have no clue what it means.Error: Unable to establish connection with FAM.Do you have "FAM" or "Gamin" installed and running?I installed the net cd of Lenny and it is up to date so I don't know whats up.
I am in a class called Linux System Administration and we are setting up Fedora 8 as a server. Per the class instructions, I have changed the default runlevel to 3 so the system always boots to a command line. The instructions say log in with your regular user account [I KNOW HOW TO DO THIS] and use the startx command to load GNOME. [I HAVE NO IDEA HOW TO DO THIS]
I searched the Internet and the text book, but found nothing I could understand.
I keep getting the following error message every time I try to open the Hipo iPod Management Tool:
Code:

I am unable to open .rar file on debian lenny. unrar-free has been installed but it does not open the .rar file. Is there another software i need to install?
In my household a number of people use the internet. Up to a maximum of 3 wired connections and 2 wireless connections at its peak, all connection through my D-LINK G604T router. The problem is, when one person is downloading or watching ..... or whatever, the others using the internet suffer. I've spent hours configuring QoS on my router, and long story short, no matter how I configure it, it just simply does not work. QoS in no way shape or form limits connection speed (which it says it should). Anyway.
I have a spare computer under my desk, and I'd like to know if I could set this up with a (free) linux distro that limits bandwidth speed per connection. For example, of the 1500 kb/ps (about) my modem pulls, is there a way to limit that to 768 or 512 per connection? so person A can still download, person B can still watch ....., and person C can still play counterstrike with a latency under 100. This would solve many, many arguments in my house I am *fairly* good with computers, but if the distro came with documentation and a GUI that would be awesome.
* TL;DR: * Is there a linux distro I can load on a spare computer that limits bandwidth per connection, wireless or otherwise, with good documentation? Failing that is there firmware I can use for my modem (dlink g604t) that would do the same? Failing that do you know of any good hitmen that would solve my family arguments, ahem, permanently?
I use Debian Jessie 8.2 and I am using a 3G connection using this modem => [URL] ....
The 3G connection works fine, except after 24 hours the connection drops and I cannot reconnect. If I reboot the computer, the connection will work again.
My guess is that my ISP gives me a new IP address after 24 hours and somehow my system cannot handle it.
How can I reconnect my 3G connection without rebooting?
I have already tried the following commands:
Code: Select allsudo service network-manager restart
Code: Select alldhclient -r eth0 dhclient eth0
Code: Select allsystemctl restart ModemManager
Results of journalctl and grepping my connection name (SFR)
Code: Select allsept. 22 17:58:19 ark1 NetworkManager[512]: <info> Policy set 'SFR Web / Prepaid 1' (eth0) as default for IPv4 routing and DNS. sept. 23 18:17:07 ark1 NetworkManager[9446]: <info> new connection /etc/NetworkManager/system-connections/SFR Web * Prepaid 1 sept. 23 18:17:08 ark1 NetworkManager[9446]: <info> Auto-activating connection 'SFR Web / Prepaid 1'.
[Code] ....
As you can see sept 22 at time 17:58 is when the computer started up. And roughly 24 hours after it failed to reconnect.
Also I should mention that there is a script to run the command:
Code: Select allsudo service network-manager restart
if the computer cannot ping a server, ie if the connection is lost.
More journalctl info when the system tries to reconnect:
Is there any reason why taskjuggler is not included in openSUSE? I can see a version available in openSUSE Factory but it is not built with latest libs. I have several of my friends asking for Project Management software under openSUSE and I don't know what to advise them.
I'm trying to get my Intel HM55 GMA HD graphics card to work in Debian Lenny.As the vanilla Xorg didn't have any support for it, I manually compiled the last stable Xorg source (1.7.1 - such a pain) and the Intel driver. But when I try to launch X, I get the following message :
(EE) GARTInit: Unable to open /dev/agpgart (No such file or directory) (EE) intel(0) : /dev/agpgart is either not available, or no memory is available for allocation. Please enable agpgart.
Sometimes, I am unable to open the CD drawer whether there's a disc in it or not. I have a Dell laptop which gives me approx 4 methods to open the drawer:
1. Press the eject button on the drawer, 2. Type 'eject' from a command line, 3. Press 'fn + f10' on the keyboard,
I'm experimenting with old linux Distributions again, and while trying tostart an x server, I get the following error message:X: unable to open display ''That makes me think that the config file is incomplete, but I would have no idea how to make it. If there is an auto configuration utility that I do not know about for X, it would be great to hear about. Here are some other specifications that might help:*Host: VMWare Workstation on Windows XP Home*Distribution: Debian 2.2 (potato) (Yes, I know it's old.)*Connection: Local. I've heard of people having difficulties like this on remote connections, but I am on the physical computer
I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesn´t get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesn´t seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.
Well after messing with compiz Opacity I managed to make all panels and windows transparent. Only thing I see is desktop background and icons. Tried ctrl+although+f1 and running gconftool-2 --recursive-unset /apps/compiz Then a reboot. Same issue. Next ran metacity --replace I get: Windows manager error: Unable to open X display
In my system I installed Oracle enterprise linux.while installing I installed Mysql also.
I checked the version which is 5.0.15
After my installation,I am installing Bugzilla 4.0.at that time it's showing below =========================================================== Checking for DBD-mysql (v4.00) found v3.0007
For MySQL, Bugzilla requires that perl's DBD::mysql 4.00 or later be installed. To install this module, run the following command (as root):
/usr/bin/perl install-module.pl DBD::mysql =========================================================== I ran below command #/usr/bin/perl install-module.pl DBD::mysql
I have a backtrack distro on a usb stick. I wish to do the following :- (a) Partition the usb stick to have a ext3 filesystem, so that the instln may be persistent for the changes. But the fdisk utility creates partitions as dev/sdb1p1 and /dev/sdb1p2. These however, could not be accessed by mkfs utility. How to overcome this problem. (b) Next , I downloaded the nessus .lzm file and put it in the /base/module dir. But unable to start the nessus daemon. It suggests an error regarding unable to create /opt/nessus and /etc/nessus/nessusd.conf. I think starting nessus as root would help but the problem persists!
I recently installed a software package that needs a command called 'daemon' to be able to start up. Slackware doesn't seem to have this command and I'm unable to find it. Where can I get it and what exactly is it that it does?

I have got a laptop running Debian squeeze. I wish to share the wireless connection of the laptop (wlan0) to the ethernet port of the laptop, so that I can share the wireless connection to my desktop PC which is connected to the ethernet port.
I have read the article on Ubuntu community: [url]
I followed the steps, and the /etc/network/interfaces file on my laptop is:
Now the situation is: My laptop can connect to Internet (i.e. ping debian.org from laptop is fine), my desktop PC can connect to my laptop (i.e. ping 192.168.1.1 from desktop PC is fine). However, the desktop PC cannot reach the Internet.
I also read the information on Debian Wiki: [url]
It seems I must install and configure ebtables before sharing my wireless connection to ethernet port. Is it true? (But why the article on Ubuntu community doesn't mention it?) Or I just made some mistakes?
I am unable to access the File Management properties.I go System > Preferences > File Management.I get a "Bug Buddy" window (I filed a report, details below).Or, it also happens if I type: 'nautilus-file-management-properties' in the terminal.
I tried to achieve this by disabling 'Enable display power management' checkbox in the 'Configure Desktop -> Display -> Power Control' KDE configuration dialog. That didn`t help and display still goes into standby mode after some period of inactivity. Also, I tried to disable dpms functionality by calling 'xset -dpms'. That didn`t help too. Note that 'xset dpms force standby'
I have this very weird problem: I'm not able to SSH to 1 specific server on the web. I can access everything, but not that specific server.
When I try to SSH, I get this code...
When I reboot to Windows, I can SSH using Cygwin. I'm using Ubuntu 10.04 Lucid and OpenSSH client 1:5.3p1-3ubuntu6. I tried sniffing the network with Wireshark, but I cannot understand why the TCP connection cannot be set up. I'm sure it's an Ubuntu problem as I'm able to connect to that server on the same machine, but different OS.
