For some reasons I have 2 bond interfaces:
bond0 4x1G for public network with PVE with OpenVSwitch.
bond1 2x10G for Ceph. Note: this network is absolutely isolated on dedicated switches with no uplink.
By default migration was done on the public network instead of the Ceph. Having the...
All old proxmox users know how frustrating it can be to migrate your enviroment from 3 to 4 or even to 5. Ad there is many many other reasons why you some times want migrate your vm's from cluster to another.
There is dirty hack for that.
- copy from your local machine authorized keys your...
I want to perform a live migration from Proxmox 5 to Proxmox 5 on a different server in a different data center. Both servers have completely different IP subnets. Is there a way to map the IP addresses? Or should I change them inside the Proxmox terminal on each VM before the migration? I only...
I have a failing hard drive on one of our nodes. So I had to migrate my running VMs to another node. I succeeded but it was not as easy as I thought.
A little summary of the setup of that server. Proxmox 5.1 is installed on an hard drive. The pve volume group is on that drive. I have...
I have installed Proxmox VE 5.1.3. I have created 4 other VE servers and clustered successfully. But when I try to do the live migration, It fails. The following is the error code I get
2018-01-15 21:19:34 starting migration of VM 101 to node 'r3' (10.10.5.1)
we have a 3 nodes cluster which are correctly working with high availability,
Last night, one of our nodes had an outage, so the HA-Manager migrated all VMs to another node as expected.
But I noticed that all of our VMs get rebooted after migration, this caused some issue with VMs, since some of...
has anyone installed CRIU in proxmox nodes to experiment live migration?
How did you do so?
I know it's not stable and I'll not install it on production. I would like to install it on my laboratory (kind of sandbox).
Any guidance would be great!
Thanks in advance
I am serving a videoconference application and I want to compare the performance between VMs and LXC, specially in case of migrating the server.
For VMs, I have an NFS server where I store the disk of the VM hosting the server. Now, I wonder how to set up the configuration of LXC to...

CRIU has not exactly been standing still. Version 3.6 is pretty solid and utilized by Ubuntu LXD server with good results; it doesnt seem like an insurmountable feature to...
I have already a cluster of 3 nodes and I would like to enable proper VM Live migration, i.e. unnoticeable downtime. Right now I have my VMs using local-lvm (LVM-thin) and therefore live migration is not allowed (you can use --with-local-disks but there's noticeable downtime).
I know it's possible to define specific interface (which is not the pve-cluster interface currently used) and bandwidth limit related to live migration. What are the related config files (with right syntax as well) ?
Do we have to restart something for these new settings to apply ?
The problem found in thread https://forum.proxmox.com/threads/slow-livemigration-performance-since-5-0.35522/, but there discussed live migration with local disks. To not hijack that thread, I open new one.
In PVE 5.0 after live migration with shared storage, VM hangs for 2-4 seconds. It can be...
This doesn't seem to be the already mentioned ssh problem (which is at 1:7.4p1-10 anyway):
Jul 11 18:34:38 copying disk images
Jul 11 18:34:38 starting VM 103 on remote node 'bowie'

We have done new setup with 3 hosts HA Cluster, We are doing migration from Host1 to Host2/Host3, its showing error
Offline Migration Issue:
When we do offline migration its migrating to other Host, but while starting VM in other Host its getting below error "TASK ERROR: volume...
We have a VM that we would like to attach a USB device to, using USB passthrough. However, it is also an important VM that must have minimal downtime, so we need to be able to live migrate it to other PVE cluster members when doing server upgrades etc.
I would like to know if it is possible to...
Please forgive the dumb question(s).
3 servers, set to cluster, and in quorum.
Each have their own LVM volumes where volumes are mounted with EXT4 filesystems so directories and disks images are readable/viewable as files on the file system, i.e. each server has a mounted...
I have 3 node on proxmox 4.3. There are in cluster.
2 of them have glusterfs server 3.5 (official on proxmox).
Cluster works perfectly, glusterfs works good ,ha works fine and online migration works fine.
In HA i have one group and all vm's add to this group.
Everything works well...
Upon upgrading our cluster to PVE 4, I just realized that live migration of KVM guests on ZFS local storage (zvol) still does not work. Since vzdump live backups do work (presumably using ZFS snapshots), I wonder why it's not implemented for migration, and when is it expected? Is it on the...
Sorry for the stupid question. I've a three nodes cluster running PVE 4.1. On one of the nodes, yesterday, the latest package upgrades were manually updated, including alle the pve debs and the latest kernel. Before the upgrade, all the running VMs were migrated to the other hosts...
