Thank you! How could the admin do to grant me with permission to run virsh as unprivileged user? Also by configurating libvirtd.conf, unix_sock_group? 2014-10-28 Allen Qiu 发件人：libvirt-users-request(a)redhat.com 发送时间：2014-10-28 00:00 主题：libvirt-users Digest, Vol 58, Issue 33 收件人："libvirt-users"<libvirt-users(a)redhat.com> 抄送： Send libvirt-users mailing list submissions to libvirt-users(a)redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/libvirt-users or, via email, send a message with subject or body 'help' to libvirt-users-request(a)redhat.com You can reach the person managing the list at libvirt-users-owner(a)redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of libvirt-users digest..."

[libvirt-users] Using virsh on OSX to control a VMs on a linux machine
by Johannes Kastl 25 Oct '14

25 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, maybe this is a stupid thing, but Google found no answer. So, for the next one trying this: I have a linux server, that runs a couple of VMs, and on which libvirt and virsh work like a charm. From time to time I'm on a Mac OSX machine, where I can install libvirt from macports very comfortably. But this far I have not gotten it to work with anything apart from the virtualbox that is installed on osx. I always get a hangup error, that is not listed on http://wiki.libvirt.org/page/Failed_to_connect_to_the_hypervisor: > error: failed to connect to the hypervisor error: internal error: > received hangup / error event on socket So I had to enter the path to the socket (on the linux machine), as the OSX libvirt thinks it is in /opt/local/..., where the whole macports stuff is. On linux it's in /var/run/libvirt/. So, the following works: > virsh -c > qemu+ssh://example.org/system?socket=/var/run/libvirt/libvirt-sock > list --all Regards, Johannes - -- `Even if I could, I wouldn't. Scars can come in useful.

[libvirt-users] libvirt guests graceful shutdown upon hosts powerdown/reboot
by lejeczek 25 Oct '14

25 Oct '14

hi everybody by an assumption I expected VM guests to be shut down/off gracefully when the host is being powered down or rebooted, but this does not seem to be the case so I wonder.. Am I missing some libvirt components/packages ? Or my assumption is incorrect and guests have to be shutdown manually? it's all SL 7 and guest are M$ regards P.

by Robert Li (baoli) 24 Oct '14

Hi, I’m an openstack developer trying to use Assignment from a pool of SRIOV VFs in a libvirt <network> definition from this link http://wiki.libvirt.org/page/Networking My question is is it possible for nova (the openstack compute) to know which VF out of the pool will be allocated to a VM before it invokes libvirt to launch it? Thanks In advance, Robert

[libvirt-users] Public IP addresses are not logged in VMs
by Roland Giesler 24 Oct '14

24 Oct '14

Anyone that can help me solve this one? I have around 4 VM's on a server and the network is bridged and a /28 public IP range assigned to it . When a client connects to one of the VM's, they all always log the address of the host server, never the client ip address. How can I fix this? Things I have investigated: 1. Switch to routed network. That would not help, since I would firstly need another public IP subnet to route to (the virtual machines). 2. Could have something to do with the libvirt firewall rules, but they are default, I didn't touch them I have read many posts in forums and websites, but none make any mention of this behaviour. Help would really be great!

[libvirt-users] Libvirt with containers
by Anjali Kulkarni 21 Oct '14

21 Oct '14

Hi, I am trying to define a container using libvirt, and I need to allow access of the device /dev/uio0 on the host on the container as well. That is, I have the following line in the container config file: lxc.mount.entry = /dev/uio0 dev/uio0 none bind,create=file lxc.cgroup.devices.allow = c 249:1 rwm And I want to add it in the libvirt XML file for the container. I tried something like: <filesystem accessmode="passthrough" type="mount"> <source file="/dev/uio0" /> <target dir="/dev/uio0" /> </filesystem> But it gave me error: root# virsh -c lxc:/// define lxc_v.xml error: Failed to define domain from lxc_v.xml error: missing source information for device /dev/uio0 Can someone pls help, how I can add the /dev/uio0 to the xml file? Thanks Anjali
