UPDATE:

Alternative method to do this:

@SOURCE NODE (=openvz node)

# ssh-copy-id -i ~/.ssh/id_rsa.pub targethost.domain.tld
# mkdir -p /var/lib/vz
# ln -s /vz/private /var/lib/vz
# ln -s /vz/root /var/lib/vz
# nano -w /etc/vz/conf/101.conf

#VE_ROOT="/vz/root/$VEID"
#VE_PRIVATE="/vz/private/$VEID"
VE_ROOT="/var/lib/vz/root/$VEID"
VE_PRIVATE="/var/lib/vz/private/$VEID"

ORIGIN_SAMPLE="pve.auto"

# vzmigrate targethost.domain.tld 101

On error: "Error: Failed to stop container", migrate again! (Only this time the container is offline)
# vzmigrate targethost.domain.tld 101

@DESTINATION NODE (=proxmox ve)

# vzctl restart 101

ORIGINAL ARTICLE/METHOD
-------------------------------------------------------------------------------------

In this article I describe the process of moving an openvz container from a openvz server to a proxmox VE host.

The challenge:

• we want to have a minimum of downtime
• we want /etc/vz/private/101 and /etc/vz/root/101 moved to "Proxmox directories" /var/lib/private/101 and /var/lib/root/101

Requirements:

• a running openvz host
• a running proxmox host

The plan:

1. reconfigure "root" and "private" dirs of the container to fit proxmox
2. alter container's configuration file and stop container
3. do a second sync of earlier mentioned directories
4. restart the container
5. migrate the container to the proxmox host (over a SSH connection)
6. fix the container's configuration at the proxmox host

Example to migrate container 101 to proxmox VE at another host node (targethost.domain.tld). Run these commands as root user.

@SOURCE NODE (=openvz node)
# mkdir -p /var/lib/vz/private
# mkdir -p /var/lib/vz/root

# rsync --progress -a --delete \
--include="/*/dev/console" \
--include="/*/dev/initctl" \
--include="/*/dev/null" \
--include="/*/dev/zero" \
--exclude="/*/dev/*" \
--exclude="/*/proc/*" \
--exclude="/*/sys/*" \
--exclude="/*/tmp/*" \
--exclude="*lost+found" \
/vz/private/101 /var/lib/vz/private/

# vzctl stop 101
# nano -w /etc/vz/conf/101.conf

#VE_ROOT="/vz/root/$VEID"
#VE_PRIVATE="/vz/private/$VEID"
VE_ROOT="/var/lib/vz/root/$VEID"
VE_PRIVATE="/var/lib/vz/private/$VEID"

# vzctl start 101
# vzquota drop 101

# ssh-copy-id -i ~/.ssh/id_rsa.pub targethost.domain.tld

# vzmigrate targethost.domain.tld 101

@DESTINATION NODE (=proxmox ve)

# nano -w /etc/vz/conf/101.conf

ORIGIN_SAMPLE="pve.auto"

# vzctl restart 101
