Hello I have a question about live migration when libvirt requires sasl authentication. I have managed to configure remote access for user nova with sasl enabled (credentials stored in auth.conf - https://review.openstack.org/#/c/12706/). It looks like live migration do not use these credentials at all. What is more it thinks that sasl is not not configured: 2013-07-01 09:49:09.317+0000: 17997:

Hi, I have a VMM application using a homegrown client for communicating with hypervisor. I am planning to migrate to libvirt because of the blocking nature of the calls. After going over the architecture, I would like to have a few doubts clarified 1) Should my application be necessarily multi-threaded in order to make use of the non-blocking calls in libvirt. [Are overlapping methods mainly used

Hi, I am installing OpenStack on Red Hat 7.5. For Nova compute component, I choose libvirt and Xen. However, I am running into some problems. It seems libvirt is unable to communicate with Xen. Xen installation: I installed Xen410 using "Xen make easy" https://xen.crc.id.au/support/guides/install/. Here is a list of packages installed and verification that Xen is running. #

I see. I also know OpenStack uses libvirt, nova-compute has a driver for communication. I have briefly looked through these 10 thousand lines of code in overall on github for openstack's libvirt driver and didn't notice any user info as well. To make the picture full don't you know is there the same scheme there: some high level openstack api with user information and passing only

Hi folks, I'm having a issue in the standard NFS driver on OpenStack, that uses qemu-img and libvirt to create snapshots of volumes. It uses qemu-img in the Controller to manage the snapshots when the volume is not attached (offline) or calls the Compute (which calls libvirt) to manage snapshots if the volume is attached (online). When I try to create/delete snapshots from a snapshot chain.

Hi, My nova-compute nodes was running libvirt 0.9.13 and QEMU 1.0, after libvirt was upgraded to 1.2.2, the VMs launched by libvirt 0.9.13 can't attach volume any more, i.e. "nova volume-attach <vm-uuid> <volume-uuid>" doesn't work. But before the libvirt upgrade, the same VM can attach volume disk. I did some debuging and find that, it failed in QEMU when try to

Hi everyone, I've some doubts regarding the usage/working of libvirt-lxc with openstack. I'm doing a project titled "Low density virtualization for Storage cloud" 1. Can i use libvirt for lxc with Openstack swift alone (excluding nova, glance and keystone)? If no what other openstack components should i use for virtualization? (Is it necessary to install openstack nova to do

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

Hi, I was wondering if multiple remote agents can access the same libvirtd. How do we prevent conflicting commands from the different agents. Can different access permission be set for the agents? (The documentation usually goes over the case where one agent can access multiple libvirtd and not this case) Thanks Arvind -------------- next part -------------- An HTML attachment was scrubbed...

Dear all, In my applications, the real-time performance is very important, so I used 4 containers, with only one application running in each container and a physical CPU core is only dedicated to one lxc. and I must know which container is hosted by which CPU core. That is, I need to pin a specific lxc to a specific CPU core. I can achieve this in a native linux system by the following xml

?Hi, ?I've installed libvirt-0.9.13 on RHEL6.2 from the source code. I cannot make sVirt working with LXC. (sVirt works well with KVM, though.) I can start an LXC instance, but the label of the process is not right. Can someone help me? I tried to change /etc/libvirtd/lxc.conf file to explicitly enable security_driver = "selinux". But it ends up with error saying "error :

Hi, I am running OpenStack Cluster and use libvirt + cgroup to limit vm’s performance https://wiki.openstack.org/InstanceResourceQuota What I am confusing is.. 1. After running a vm instance with some croup limit applied, I can’t find any related cgroup settings. 2. Can I change limit value after instance is running? like change disk_read_iops_sec from 10 to 20. One of the xml file like below.
