Fedora X86/64bit :: Connecting To Xen Hypervisor Fails
Jun 14, 2009
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.
I'm using a Lenovo B450 laptop with Fedora 14 x86_64. The laptop has a Atheros AR5001 wireless adapter and is identified at lscpi.
Additionally lspci reports that the kernel driver in use and the kernel module for that device is ath5k.On a fresh install of Fedora 14, the NetworkManager applet seem to behave well at enabling and disabling wireless (remember the "Enable Wireless" checkbox). Though wireless was always at disabled state at every boot time, even if it was enabled at the toggle button on the laptop. Now that, after I have fully updated the system (yum -y update), I'm unable to enable wireless. Clicking on the "Enable Wireless" menu item on the NetworkManager applet has no effect, and I've a confirmed report that the update broke this functionality (I reinstalled F14, and then it was working, full system update broke the function).After the update, the kernel version is 2.6.35.10-72.fc14.x86_64 and the NetworkManager version is 0.8.1-10.git20100831.fc14.x86_64.
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 just tried to update to kernel 2.6.27.15-170.2.24.fc10 (x86_64) at the suggestion of the gnome update widget, and the process hung. A bunch of other things were updating at the same time, many of which were related to audacity or wine.
I'm not sure just what was being updated, because the option to review which updates are available does not work - when I click on it, nothing happens, but when I take the other choice (install all updates), I take pot luck. It would be nice to be able to choose which programs to update, and to be able to upgrade the kernel independently, but I don't seem to be able to do that at the moment.
my update today failed, because the packages raydium and maniadrive depend on libphp5-5.2.9.so, which is provided by php-embedded, which is (apparently) not in the fedora 64bit repository There does however seem to be an i586 version...
After the 4th install The printer will at least produce a test page, but the available resolution is low, I suspect I need the gutenprint enhanced drivers, printer is a EPSON R285. Where do I find the nvidia libs so I can use the Nvidia driver for my ancient 8500 GTX. Using the package manager find nvidia shows nothing.
Are these libs held on another repo, as in other distros?, and is Acroread availble? is there a listing if the repos somewhere, I have some apps that have to be compiled and are a pig to get going, due to using those funny cut down libs that ubuntu use. When I backed up the last failing version of FC13, which hung as soon as yum was started, didn't print ect, I didn't close firefox down before copying the file. So the user config is locked, ie, you get firefox is already running, and fails to start. I found parentlock and deleted it, but but there is another lock file that needs to be removed, and I can't find it.. Anyone know the location of the lockfiles for firefox.?
Im trying to build Mandrivas theme ia_ora from source but it fails.

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've configured an openvpn server on a wrt54g using dd-wrt firmware. I can connect from the command line...at least it appears to connect, but I am unable to access any resources. Trying to use networkmanager's openvpn client fails every time. Everything I find googling relates to Ubuntu, so just for kicks I booted into my Ubuntu partition for the first time in months....and the wireless lan disappeared when I restarted network manager, which is why I don't use Ubuntu in the first place, so much for the "easier distros". I'm assuming there are people successfully connecting to openvpn servers from Slack. I could definitely use a pointer.
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)
Downloaded from here: [URL] then ,it is 32-bit and I need to know what all 32-bit libs are needed as dependency for skype to work. I am on Gnome Fedora and purposefully selected static version of skype to prevent installation of libqt4.
I just bought sony vaio laptop(EB16) couple of days before.I had window 7 OS. Two days before i downloaded Fedora-12-x86_64-DVD & installed in my PC.Everything is working fine except when i play any video or audio file such as .avi, .mp3 from any player such as vlc player, movie player ,xine etc , i don't get any sound.I tried to search this problem in internet but still i am not able to resolve this problem.

Can anyone get the website below to work correctly with Firefox 3.5 and F11 64bit?[URL]...All I see is the background scrolling slowly and jerkily, none of the buttons at the bottom work. Reboot into Windows 7 and IE8: the same site is fast, smooth, the buttons work and the product details appear correctly in the centre of the screen.
I've tried disabling all adblock /pop up block options, ensured all javascript options are enabled and no change. Could this be a problem with the 64 bit flash player (installed from leigh's sticky thread) or a problem with OpenJDK?
Edit: now working, thanks very much Leigh and Dangermouse.
Anyone successfully installed AIR and iPlayer on F11?
I've switched to 32 bit Adobe flash, tried Autoten for AIR and Dangermouse's advice for iPlayer: url.html but it's not working, and trying to install AIR from url results in an endless busy downloading graphic .
I assume my problem is a lack of required packages, though I searched the repositories using YUM extender for the packages listed here: url.html and can't see them either as installed or available.
i have a asus K8N-DL MB with 2xAMD64 opteron270 and 4G ram3x1TB drives in raid 5 using onboard SIL controllerand 2 SATA drives also on SIL but not raidedhad previously had F10 64 bit loaded whick workedtried to upgrade and failed (destroyed data)tried a fresh install low level formatted the 3x1TB and made them into raidleft other drives as is takes a long time to boot into the point of trying to find HDthen nothing found
As i just started to write scripts, i'd obviously like automize some actions, therefor i'd like to check the users system if its 64bit. Is there a function to check this?
were's a good start to get into bash scripting, the files i use as template gave pretty much good info, but yet i have no idea what i'm actualy doing
Iam trying to install F15 64bit but I failed my hardware as folow

installation media: downloaded dvd image burned the image installed correctly inside vmware and work as expected but the media boot to the first screen quistion and when press ok for new installatin the answer is a serious of errors messages (a lot of it). did my hardware not compatible??
I am new to Xen Hypervisor and wanted to know if someone has any good guides to configuring it please. Also once i configure a Guest OS how can i connect to it remotely via a windows and linux machine?
I have Intel Pentium Dual Core E2180 / 2 GHz processor. i just upgraded my system with 4 memory sticks i.e. 7GB of RAM due to my requirements. Now the issue that i am facing is that my 32bit fedora system does not showing and suppoting more than 3.XX gigs of RAM when i consult "/proc/meminfo", "free -m" and "top". Now i have done two thing, first i have installed a PAE version of kernel. In result of this my system become two slow with the following error at startup. Error: starting udev: wait timeout. will continue in the background <Failed> Secondly, i installed a 64bit version of Fedora 10 but still it showing not more than 3GB of memory. Also a kernel bug system alerts me of not supporting more than 3gigs of RAM and ask me to send that bug to[URL]
Today I got update notification. I type in terminal yum update, and get this error: Quote: Error: Missing Dependency: libnetfilter_conntrack.so.1()(64bit) is needed by package iptstate-2.2.1-5.fc11.x86_64 (installed) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest
I removed iptstate.x86_64, again run yum update, and than, ibnetfilter_conntrack got installed. I tried to install iptstate.x86_64 again, but i get Quote:
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.
