OpenSUSE :: Hypervisor: Libvirtd Not Running
Jan 4, 2011
i'm having some issues trying to get the oSUSE 11.3 x64 hypervisor working, these are the errors im getting when i've opened the virtual machine manager, and clicked on one of the 2 options.
verify that 'libvirtd' daemon has been started:
Unable to open connection to hypervisor URI 'qemu:///system':
unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: No such file or directory
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/connection.py", line 971, in _try_open
None], flags)

It complains that it can't connect to localhost because probably libvirtd is not running. Well it is running, so please share your wisdom with me. Here is error message:

I have a tested and working ssh connection with my local network server. On Ubuntu it was simple to just add an ssh connection to Virtual Machine Manager to connect to 'hippopatamous.local' (yes thats the name of my server :P) but now that I'm in arch its different. I connect to the server using just 'hippopatamous' and on top of that its like the Virtual machine manager can't connect.
All it says is to make sure that libvirtd is running. I ssh-ed in to the server and make sure it was running. I even ran it on my local computer (this was before I remembered/realized this would be a server type daemon so running it locally wouldn't do anything)

I'm not sure if this helps and I'm not sure how to tell anyone what I found, but was a problem in Fedora 10 and 11 were VM's running in KVM would lockup due to (disk or network) IO activity. The problem silently vanished as soon as I installed Fedora 12 as my VM. I upgraded my VM to Fedora 13 and the problem re-surfaced. Oddly, no other distributions seem to have this problem any more judging from Google. My configuration:Host = x86_64, 4 cores, Fedora 11VM = i686, 2 virtual cores, Fedora 10, 11, or 13 (Fedora 12 works)What worked for me was using only one core in my VM. Things have been stable for a few days now

I just installed Fedora 15 x86-64 gold today so I could try out the Xen hypervisor. I installed xen by typing in xen command line and following the installation prompts. Everything seemed to go fine on the install. The following appeared in /boot:
[Code]....
However, when I rebooted there were no boot options. I saw than /boot/grub/grub.conf had no entries for a xen kernel so I modified grub.conf to show a boot menu and added a thrid kernel boot option (xen 4.1.0). I'm unsure if the lines I added are proper. Now when I reboot choosing third option (xen 4.1.0) I get a boot error message that "Error 19: Linux kernel must be loaded before initrd". I'm guessing that the issue is that xen-4.1.0.gz isn't becoming the kernel. At this point I'm stuck. I'm not sure if this is a xen on 15 issue or I'm just making some newbie mistake in grub.conf. Anyone see an issue or can confirm/not -confirm that xen works on 15 x86-64 gold?

I'm using fedora12 with KVM. I'm also using iptables for filtering and nat. Problem is when I start libvirtd, it overwrites my current iptables and iptables config file (/etc/sysconfig/iptables).
Ok it leaves an old copy in /etc/sysconfig/iptables.old, but the main problem is that it removes also all my custom settings from filter and my full nat. I would like the keep control on my iptables and like to manage them on my own. But I cant find an option in the libvirtd config files and/or the libvirtd startup scripts to prevent libvirt from changing my iptables. how I can make libvirtd stop tempering with my iptables?

I've just installed Fedora 11, and in the process of testing it, decided on trying out virtualization tools.
Services: libvirtd, xenner and xend are started and i'm still unable to connect to hypervisor with the message:
Unable to open a connection to the Xen hypervisor/daemon.
Verify that:
- A Xen host kernel was booted
- The Xen service has been started
Unable to open connection to hypervisor URI 'xen:///':
<class 'libvirt.libvirtError'> unable to connect to 'localhost:8000': Connection refused
None
xend.log is empty
Now, I've also tried installing Fedora 11 x86_64 as a guest OS with KVM/QEMU as a solution, and the installation process starts, but after some time, the console screen goes black and there is no DVD driver activity or HDD led activity. The CPU is at 2-5 % utilization. And there is nothing I can think of to 'resume' the installation or whatever.
[Code].....
Now, I've tried the same thing 3 times and the process always hangs during the installation with the same symptoms.

Unfortunately accidentaly I disconnected my usb drive my computer and my VMs run from so I just rebooted for a quick fix Now I can't open virt-manager locally and the VM's can't get network connections I see this in the logs after the last two reboots
Code:
grep lxc /var/log/messages |tail -n 2
Jan 7 00:45:04 F820 libvirtd: 00:45:04.524: warning : lxcStartup:1895 : Unable to create cgroup for driver: No such device or address
Jan 7 11:52:53 F820 libvirtd: 11:52:53.325: warning : lxcStartup:1895 : Unable to create cgroup for driver: No such device or address
[code]...
I tried restarting libvirtd after with no love so I rebooted and cgroup was gone this was a clean install of F14, after this started I brought the system current, I can provide the packages installed but they errors didnt change

After each boot I find 2 occurrences of WARING! Can't find hypervisor information in sysfs!
in /var/log/boot. This box is running as KVM-host, so I am a bit worried about 'warings' like these...

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 installed a new squeeze serverXen Hypervisor runs the server as Dom0 anda virtual Windows XP.The server runs samba, postfix, dovecot, squid, cups and hylafax with a Frritz ISDN card (module fcpci.ko).The used memory of Dom0 rises slowly (about 5MB /h) until the system crashes.As a workaround i installed a reboot every 24 hours.htop shows normal behavior.The system is already in production, so i can't stop services to track this bug.I need some hints how to debug the running system to find out, where the memory gets lots.

I've been trying to install Ubuntu Server onto Microsoft Virtual Server at the request of my boss, and I've been having an issue I cannot seem to work around. Now my background on Ubuntu and linux in general isnt amazing, I have configured server at home to act as a file sharing platform and a media server, but thats about it.
Now I've gone to install it on the MVS at work and once the install completes, I recieve the following error: Hypervisor error.JPG
I've tried running the install but limiting the resolution, but from what I can rememeber server doesnt install the GUI to start with, so it should just be showing me the standard CLI.

I'm going to boot up a desktop (that has a cd burner) from a USB stick of openSUSE 11.3. Will I be able to burn an iso (that's on the desktop's harddrive) to CD, i.e. can I use the cd burner, if I've booted from a USB stick?

Im comming from ubuntu/mint and one of the things I got used too was doing something like "sudo nautilus" or "sudo gedit" and similar things. In Suse 11.3 I always get errors like the following
(gedit:6115): Gtk-WARNING **: cannot open display:
kate: cannot connect to X server
Could not parse arguments: Cannot open display:
or similar variations of these.What can I so to prevent this from happening? even if I do "su" and try from there it doesnt always work.I like Suse as it feels more professional then ubuntu, but I am trying to make it as user friendly.

1. Issue booting from grub The Xen kernel option in grub starts then the screen goes black and after a few seconds white starts to creep in from the edges.
2. When I run Virtual Machine Manager I get this message.
A hupervisor is not running. For Kvm, load the kvm kernel modules. If you want to run xen, reboot and load the xen kernel. The last options causes the error mentioned under issue 1.

I am having a hard time getting repositories to install and even some applications. Do I use yast to install RPM's aned what about if the file is a zipped up tar file? If you are familiar with VMware, can we play cd's, rip them and burn and so on?

Is it possible to run ktorrent from a command-line, or more to the point:from a cron job I like ktorrent, it does it job well. But it bugs me that I have to log inand remain so, just to run an app who's interface is not even required mostof the time.Unfortunately, my provider imposes a montly volume. Nice big volume, but notimposible to run it dry. On the other hand, they count nightly traffic atonly half to actual volume.So I'd like to be able to start ktorrent at a certain time after midnight,and interrupt it at dawn. Or maybe just shutdown the machine at dawn.

I am trying to run php as cgi script with apache and opensuse 11.3. I disabled the mod_php and installed mod_fcgid, and php-fastcgi, as per the instructions here. I have been trying to achieve this, but, somehow it is now working. I can see the page if i have an index.html, but if i have index.php, it downloads it as a file. I really tried to set this thing up for more than 12 hrs now. I am soo frustated.
my /etc/apache2/vhosts.d/shekhar.conf
my /srv/www/wrapper/shekhar/php5
my /etc/apache2/conf.d/mod_fcgid.conf (I uncommented the lines inside the <FilesMatch > Tag., it gave me same result, even after uncommenting the tag.)
my /etc/apache2/httpd.conf

Does anyone has a start of a clue to explain me why? Soes anyone could tell me where to start to look for the reason!Note that the last time the problem occues (i.e. 10min ago) was on this site (no other tab opened).My configurationSONY Vaio VPCF11S1E: Core i7 720QM, 6GB RamOpenSUSE 11.3 64bits.
