similar to: Live Migration Without Shared Storage

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

Hello, my project still uses VBoxManage but I am inclined to switch to libvirt, if possible, because I like the concept. Some rather unusual commands are used by my project... VBoxManage modifyvm "$VMNAME" --synthcpu on VBoxManage setextradata "$VMNAME" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1" VBoxManage modifyvm "$VMNAME"

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

Hi, We have been trying to get live migration working between two xen boxes running libvirt 1.2.12, However i seem to be getting the following error root@libvirt-xen1:~# virsh migrate --live trusty-image qemu+ssh://192.168.13.9/system --copy-storage-all --verbose --persistent --undefinesource root@192.168.13.9's password: error: unsupported flags (0x48) in function

Hi libvirt support, Can you please give me some example of how to use "virsh migrate --live" with p2p option including both source host and target host? I try to get some info from your website, but no info with migrate. [root at vmoactive02 qemu]# virsh help migrate NAME migrate - migrate domain to another host SYNOPSIS migrate [--live] [--p2p] [--direct]

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

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was

On libvirt 6.8.0 and qemu 5.1.0, when trying to live migrate "error: internal error: Failed to reserve port" error is received and migration does not succeed: virsh # migrate cartridge qemu+tls://ratchet.lan/system --live --persistent --undefinesource --copy-storage-all --verbose error: internal error: Failed to reserve port 49153 virsh # On target host with debug logs, nothing

I use libvirt to manage a QEMU/KVM system. Starting a VM only by using > virsh start vmname What I want to know is how to add an option to virsh vm's start script, in my case I want to add QEMU logging option (-d and -D). I can see from > ps aux | grep qemu that current VM started using virsh not including those options ~ady

How is tunnelled option specified during migratiion different than an ordinary ssh connection specified as:- virsh migrate vmName qemu+ssh://user@remotesys/system?

The reason given is shut off (crashed). So something virsh backup-begin does is causing he guest to crash?

Title: HOWTO-FreeBSD-on-XCP Author: John D. "Trix" Farrar Date: 2012-02-09 * The Challenge - ParaVirtualized FreeBSD 9.0-RELEASE under XCP 1.1.0 The idea here is to create a PV FreeBSD VM under Xen Cloud Platform (XCP) without starting with an HVM first.

TLDR: Why is virsh migrate --persistent --live domain qemu+ssh://root@host/system --xml domain.ceph.xml not persistent and what could i do about it? 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

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://

Hi folk, we are using 10gb NICs with multithreaded compression. We're finding that the standard `virsh migrate` gets at most ~1.2gbps, similar to a single scp session. When we do a multipart upload with multiple scp connections we can squeeze as high as 9.6gbps. Is there was a way to get `virsh migrate` to perform multiple connections as well when transferring? Would be useful to be able
