Libvirt newbie, need help with doubts
Hi, These are my doubts: 1. I tried live migration of Ubuntu 11.04 from the one physical machine to another using the migrate() function. I connected via tcp in the destination URI and migrated successfully(lesser than 2 seconds). I tried running virsh list --all on the destination PM and confirmed that the VM had been migrated successfully. When I tried checking ps aux | grep vmname where

couple of ceph/rbd questions
Hi, I've recently been working on setting up a set of libvirt compute nodes that will be using a ceph rbd pool for storing vm disk image files. I've got a couple of issues I've run into. First, per the standard ceph documentation examples [1], the way to add a disk is to create a block in the VM definition XML that looks something like this: <disk type='network'

Hi, after years of beeing pleased with local storage and migrating the complete storage from one host to another, it was time for ceph. After setting up a cluster and testing it, its time now for moving a lot of VMs on that type of storage, without

Clarification about virsh migration options
I am trying to work out what all the options are for migrating a KVM machine to another KVM machine, without using shared storage. The documentation is not quite verbose and not intuitive, so I'm hoping someone can explain this to me. The man pages show this syntax: migrate optional --live --p2p --direct --tunnelled --persistent --undefinesource --suspend --copy-storage-all --copy-storage-inc

release open_disk error
Hello, I wonder what the "open error -1" / "release open_disk error" messages in sanlock.log actually mean. I saw these messages in the log on a KVM host that rebooted, and after running "/usr/sbin/virt-sanlock-cleanup" on that host. The resources where disks from 2 guests running on another KVM host. So in fact the disks are still in use, bot got cleaned up by

Support live migration of OpenVZ container
Hi libvirt team, I was trying to migrate an OpenVZ domain from one host to another host. It seems that the live migration of OpenVZ container is there ( https://openvz.org/Migration_from_one_HN_to_another), but it haven't been integrated to libvirt yet. In particular, I ran the following commands and it failed: $ sudo virsh migrate --live --verbose --undefinesource 101 openvz+ssh://

Sanlock gives up lock when VM is paused
Hello, I'm using libvirt and sanlock on qemu-kvm guests. Each guest has it's own Logical Volume for it's root filesystem. Sanlock is configured and working and prevents me from starting the same VM twice on multiple nodes and corrupting it's root filesystem. Each VM's domain XML resides on 2 servers that share the LVM volume group over fiber channel. In testing, I noticed
