Hi,

I have set up a cluster with three nodes, dedicated corosync network (two rings) and dedicated migration network.
When I login to the cluster nodes, I can reach (ping/ssh) each other using the migration network IP address.

All nodes have one single IP inside the migration network:
10.182.40.97 lxgamora-migration
10.182.40.98 lxgroot-migration
10.182.40.99 lxrocket-migration

....and are set up to use this network:
root@lxgroot-mgmt:~# grep migration /etc/pve/datacenter.cfg
migration: secure,network=10.182.40.97/27

Maybe it is important:
I am using openvswitch for the networking -- the /etc/network/interfaces part for the migration network looks like this:

allow-vmbr2 bond2
iface bond2 inet manual
ovs_bonds enp24s0f0 enp24s0f1
ovs_type OVSBond
ovs_bridge vmbr2
ovs_options bond_mode=balance-tcp lacp=active other_config:lacp-time=fast
pre-up (ip link set dev enp24s0f0 mtu 9000 && ip link set dev enp24s0f1 mtu 9000)
mtu 9000
#Migration

iface enp24s0f0 inet manual

iface enp24s0f1 inet manual

auto vmbr2
iface vmbr2 inet static
address 10.182.40.98
netmask 27
ovs_type OVSBridge
ovs_ports bond2
#Migration Network




Unfortunately when I try migrating a running VM I get this:

root@lxgroot-mgmt:~# qm migrate 107 lxgamora-mgmt --migration_network 10.182.40.97/27 --migration_type secure --online

2019-11-20 17:21:16 migration xbzrle cachesize: 2147483648 transferred 0 pages 0 cachemiss 0 overflow 0

--- now it hangs until it is getting killed ---

I tried with different running VMs and from/to different nodes but it is always the same result.
Do you have any hint or solution for me?


All nodes are installed with Promox 6:
pve-manager/6.0-4/2a719255 (running kernel: 5.0.15-1-pve)


The cluster itself is running and quorate:

please upgrade to the most recent package versions - especially regarding knet/corosync there have been some initial issues that are now fixed!

please also include your network, storage and VM configs. system logs from both nodes from around the time of the failed migration would probably also be interesting!
 
I did pveupdate and pveupgrade.
For testing, I removed the "migration: " line from /etc/pve/datacenter.cfg and live migration works now -- but using the slow interface.
It seems there is something wrong with my migration network configuration.

For migration I use the network 10.182.40.96/27
All nodes have a bonding interface inside this network.
The network itself works (ping / ssh from any to any node using the IP inside the migration network)

Here is the configuration of the nodes -- /etc/network/interfaces (only the migration network part)
allow-vmbr2 bond2
iface bond2 inet manual
ovs_bonds enp24s0f0 enp24s0f1
ovs_type OVSBond
ovs_bridge vmbr2
ovs_options bond_mode=balance-tcp other_config:lacp-time=fast lacp=active
pre-up (ip link set dev enp24s0f0 mtu 9000 && ip link set dev enp24s0f1 mtu 9000)
mtu 9000
#Migration

iface enp24s0f0 inet manual

iface enp24s0f1 inet manual

auto vmbr2
iface vmbr2 inet static
address 10.182.40.97
netmask 27
ovs_type OVSBridge
ovs_ports bond2
#Migration


The same configuration is on the other two nodes, just the IP address differs:
node0 10.182.40.97
node1 10.182.40.98
node2 10.182.40.99


Each node has 6 interfaces:
bond0: VM traffic --> vmbr0
bond1: Storage/NAS --> vmbr1
bond2: Migration network --> vmbr2
eno4: Management / WebUI (Setup IP address)
eno5: Kronosnet Ring 1
eno6: Kronosnet Ring 0

When I understand it correct, migration network is not required to be a Kronosnet ring, right?
 
no, migration network can be an arbitray network. the other bonds/bridges are also all on-top of OVS?
 
Yes. Here is the full interfaces file of one node -- they are all set up the same way:

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

can you post the VM config and logs surrounding a migration as well please? and "pveversion -v" output after the upgrade

Do you need specific logfiles or just the output of "qm migrate" and /var/log/syslog?
 
Thank you, the hint with the sysadmin package repos was gold.
The non-subscription sources list was missing.
