[libvirt-users] Virtualbox HOWTO?
by Dr. Boris Neubert 04 May '14

04 May '14

Hi, I have the latest libvirt from the git repo successfully compiled and up and running under CentOS 6.5. I can connect to the daemon (started with /usr/local/sbin/libvirtd -d --listen) both locally and remotely. I cannot see my virtualbox virtual machines. They run as the user "virtualbox". I connect with virsh -c vbox+tcp://virtualbox@vmserver/session and all list --all gets me is Id Name State ---------------------------------------------------- I probably miss something elementary, especially because I am not asked for a password for the virtualbox user and did not configure any machines beforehand. But I did not find how do to the trick in the documentation. Anybody out there with a working Virtualbox setup can help me out? Thanks and kind regards, Boris

[libvirt-users] newbee questions

Hi, Im very new to virtualization on Linux, wanting to kick the tires some, and am wondering where best to go next. Right now, ive done the 'all in one install' of ovirt 3.4 on a single fedora 19 machine. Its a desktop with a wifi network interface, and im trying to set up the kvm hypervisor in combination with macvtap. Any pointers to docs on what best to do next is appreciated. Im currently trying to make sense of this: http://www.ovirt.org/Quick_Start_Guide Also, as far as I can tell, there seems to be an issue with the detection of my wireless wifi network interface 'wlp2s0' as it doesnt seem to show up anywhere in the interface. I can attach the 'ovirtmgmt' network to my standard wired ethernet interface 'p2p2', but that device is not in use on the machine and it is disconnected from the network. Reading about linux virt and issues with bridging with wifi NIC's on the web made me, perhaps incorrectly here, assume that a wifi nic might be an issue, so thats where the idea to use macvtap came from. Manual setup of macvtap seems to work, as i can do this without issues on a root prompt on the same machine: ip link add link wlp2s0 name macvtap0 type macvtap ip link set macvtap0 address 1a:46:0b:ca:bc:7b up ip link show macvtap0 But the wifi interface 'wlp2s0' does not seem to show up in the ovirt web gui interface. Im sorry if I sound confusing here, but that may be just because im really still confused about ovirt. ;) So any pointers on what to read up on or do next is appreciated, Thanks, Regards, John Smith.

[libvirt-users] virsh update-device: need to clear network filters
by Oleg Bondarev 01 May '14

Hi, Can anyone please help with the following: I have a running instance with interface <interface type='bridge'> <mac address='fa:16:3e:ba:a4:67'/> <source bridge='br100/> <target dev='vnet0'/> <model type='virtio'/> <filterref filter='nova-instance-instance-00000001-fa163ebaa467'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> what I need is to clear network interface on the instance. I tried virsh update-device with following xml: <interface type='bridge'> <mac address='fa:16:3e:ba:a4:67'/> <source bridge='br100/> <model type='virtio'/> </interface> but this results in the following error: $ sudo virsh update-device 13 xml.xml --persistent --live --config error: Failed to update device from xml.xml error: End of file while reading data: Input/output error error: Failed to reconnect to the hypervisor and libvirt is restarted. Is it possible to clear nw filter at all? Thanks, Oleg
