6th Xen Test Day is today!
by Dario Faggioli 28 Jun '13

28 Jun '13

Hi everybody, With this mail I kick off (a little late, actually... Sorry, Internet issues :-( ) the 6th, and most likely _final_, Xen Test Day for 4.3... come and join us on #xentest on freenode! We're concentrating on testing PCI Passthrough and CPU hotplug (with qemu-xen). See the test instructions for more details. We will be testing RC6 which, if everything goes fine, will the be released next week as Xen 4.3 (on July 2nd). For more info, see: - on Xen Test Days: http://wiki.xen.org/wiki/Xen_Test_Days - on getting and testing RC6: http://wiki.xen.org/wiki/Xen_4.3_RC6_test_instructions - for generic testing information: http://wiki.xen.org/wiki/Testing_Xen Ah, and Michael did it again, and built 4.3.0-RC6 for Fedora 18, so it's even easier, for us Fedora users, to participate!! Find the RPMs here http://koji.fedoraproject.org/koji/taskinfo?taskID=5551851, and refer to his message of yesterday evening for more details on them. See you all on freenode, channel #xentest.

How to create a Xen PV DomU with a dvd ISO image, using xl/xm
by ranjith krishnan 21 Jun '13

21 Jun '13

Hello, I was looking to create a Xen DomU with a .iso image saved in the hard disk. I ran into some trouble with http based install, hence looking at this option. This is what i have currently. Just wanted to know if I am on the right track here, and hoping to get some tips if somebody has similar experience. I compiled Xen 4.1.5 from source on a Fedora 17 Dom0, and I want to create DomU images. I have downloaded the .iso image for Fedora 17. I have a logical volume xmf17lvm on volume group xenvg. Here is my install profile ( will use "xm create -c xmf17install" ) name="xmf17install" memory=1024 vcpus=1 disk=['file:/home/isoimage/Fedora17.iso,xvdc:cdrom,r','phy:/dev/xenvg/xmf17lvm,xvda,w'] vif = [ 'bridge=br0' ] onreboot = 'restart' oncrash = 'restart' boot='d' builder='hvm' Its almost 3 AM here, so I am giving this a break today. Will work on this tomorrow afternoon. If anyone has any helpful hints or comments regarding my approach, please let me know. -- Ranjith krishnan

Virt-manager does not connect to libvirt/Xen? Xen 4.1.5 installed from source on Fedora 17.
by ranjith krishnan 21 Jun '13

21 Jun '13

Hello, I posted this yesterday to the Xen-devel list, posting it additionally to the fedoraproject list too. My problem is Virt-manager is unable to connect to the hypervisor (explained below). However, xm list, xm info work fine. So I followed the guide http://wiki.xen.org/wiki/Xen_4.2_Build_From_Source_On_RHEL_CentOS_Fedora and built/installed Xen from source, using grub2-mkconfig to rebuild grub and was able to reboot Dom0 with Xen successfully. Then I installed packages for virt-manager. # yum install libvirt-daemon-xen python-virtinst libvirt-daemon-config-network libvirt-daemon-driver-network virt-manager virt-viewer Everything got installed except for one package. Got an error message "No package* libvirt-daemon-driver-network* available." Now when I start virt-manager, it is unable to connect to Xen and fails with the following error. # virt-manager Unable to connect to libvirt. unable to connect to 'localhost:8000': Connection refused Verify that: - A Xen host kernel was booted - The Xen service has been started Libvirt URI is: xen:/// Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1027, in _open_thread self.vmm = self._try_open() File "/usr/share/virt-manager/virtManager/connection.py", line 1009, in _try_open flags) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: unable to connect to 'localhost:8000': Connection refused # xm list and # xm info work fine. This means xend is running right ? Did some searching, found an old thread http://old-list-archives.xenproject.org/xen-users/2010-06/msg00880.html Added *(xend-unix-server yes)* to xen configuration file xend-config.sxp and added *export VIRSH_DEFAULT_CONNECT_URI="xen:///"* to root's .bashrc. Still no luck. This might help, # rpm -qa | grep libvirt libvirt-daemon-xen-0.9.11.9-1.fc17.x86_64 libvirt-daemon-0.9.11.9-1.fc17.x86_64 libvirt-0.9.11.9-1.fc17.x86_64 libvirt-python-0.9.11.9-1.fc17.x86_64 libvirt-daemon-config-network-0.9.11.9-1.fc17.x86_64 libvirt-daemon-config-nwfilter-0.9.11.9-1.fc17.x86_64 libvirt-client-0.9.11.9-1.fc17.x86_64 So in summary, Built and installed from source Xen 4.1.5, on Fedora 17. Can boot into Xen Dom0, xm works, xend running, But virt-manager unable to connect to Xen! Please help. I have tried to give as much info as I could. Do let me know if you need more info. -- Ranjith krishnan
