[libvirt-users] qemu - could not load kernel and dynamic ownership setting
by Shantanu Pavgi 05 Mar '12

05 Mar '12

Hi, I am getting following 'qemu: could not load kernel' error while trying to create a new VM using virt-install or virt-manager. The software versions are as follows: CentOS 6.2, Libvirt 0.9.4, qemu-kvm 2:0.12.1.2-2.209.el6_2.1. The qemu.conf has disabled dynamic_ownership setting. The VM instantiation has worked fine before when dynamic_ownership was enabled (default). So is this error related to dynamic ownership being disabled? I appreciate any help on how to debug this error further. Also, is there any documentation on why/when dynamic_ownership setting should be used? We have enabled it to figure this out through some test installs but right now unable to move further with the install step itself. {{{ virt-install --connect qemu:///system \ -n $guestname \ -r 512 \ --vcpus=1 \ --os-type=linux \ --os-variant=rhel6 \ --accelerate \ --graphics vnc,keymap=en-us \ -v \ -w bridge:br1 \ --disk path=$datastore/$guestname.img,size=40 \ -l $repo \ -x "ks=$ksurl/$ksfile ksdevice=eth0 ip=$guestip netmask=$netmask nameserver=$nameserver gateway=$gw" }}} {{{ Starting install...

[libvirt-users] Unable to connect qemu:///system on CentOS 6.2 X86_64
by suyi wang 05 Mar '12

05 Mar '12

Dear all: I ust installed Fedora16Fedora16 X86_64 on my new machine, and then I ran the commands as follows(ran as root): yum install qemu-kvm yum install qemu yum install libvirt yum install virt-manager then I started the libvirtd as follow: /etc/init.d/lbvirtd start So , it ran well. However, after a few days , when I ran the command "virt-manager" , it showed as in the attachment. it seemed that ti cannot connect the hipervisor. Then I did a little test: I ran the conmand "virsh list" , but it didnot work,either. Then I used Python as follows: import libvirt cc = libvirt.open(r'qemu:///system' ) but it didnot work,either. All the test above are under root . I hope that someone can give me some suggestiion. Thanks to all!

[libvirt-users] [LXC] Attempt to start X in guest makes host X die
by Robin Green 04 Mar '12

04 Mar '12

I have attempted to start X in a rawhide LXC guest on a Fedora 16 host, using echo a > /sys/fs/cgroup/devices/libvirt/lxc/Rawhide/devices.allow to allow me to create all the necessary devices in /dev in the guest (dangerous, I know, but I only ran that command after the guest systemd finished booting). This is with the nouveau open source driver. I ran X using /usr/bin/startx -- :7 vt7 Immediately the host X server dies, even though it's on a different virtual terminal (VT1). It seems to be something to do with DRM. The /var/log/Xorg.0.log in the host says something about drmSetMaster failing. What's strange is that according to the guest Xorg.7.log, DRM opening fails there too: "drmOpenDevice: open result is -1, (No such device)". If there is no such device (even though I created it), how can the guest be affecting the host? I think it might possibly be related to https://bugzilla.redhat.com/show_bug.cgi?id=680677 Maybe the guest X immediately fails to start but for some reason does not release the DRM master (at all, or quickly enough), and the host X tries to regain the DRM master but fails and dies. I looked at some other drivers to see if any other X drivers have better handling of the latter condition, but I couldn't find any which do a retry in this case. I would report a bug, but I'm not sure which Fedora component to report this against.

by Marko Weber 02 Mar '12

02 Mar '12

Hi all, we have an easy question for you maybe. when we start the virt-manager, and doubleclick an listed virtual machine, we always bei transported to CONSOLE page. Thats very annoying for us. Is there a possibility to set an option, that on doubleclick you are getting the CONSOLE TAB. in 95% we need Console and not Details. thanks for any costructive hints. marko , from cloudy rainy germany
