Hi!

I am trying to migrate a VM from one remote node to another one but
invoking vzmigrate command from third machine (front-end). Something like
[front-end]$ ssh <remote_host_1> sudo /usr/sbin/vzmigrate --online
<remote_host_2><CTID>
But I am getting the following error when executing the command below as
unprivileged user with permissions in /etc/sudoers file to run
/usr/sbin/vz* scripts:
[front-end]$ ssh <remote_host_1> sudo /usr/sbin/vzmigrate --online
<remote_host_2><CTID>
Warning: Permanently added 'remote_hostname_1,remote_host_IP_1' (RSA) to
the list of known hosts.
Starting online migration of CT <CTID> to <remote_host_2>
/usr/sbin/vzmigrate: line 312: vzctl: command not found
Error: Can't perform online migration of a stopped container

In 312 line of/usr/sbin/vzmigrate file thevzctl is invoked as
[...]
get_status $($VZCTL status $VEID)
[...]

and VZCTL is defined in the beginning of that file as
VZCTL=vzctl

I wonder if there is any reason to define VZCTL as vzctl but not with
absolute path to it (i.e. /usr/sbin/vzctl)?

Adding /usr/sbin to $PATH in ~oneadmin/.bashrc making the following
command works
$ ssh <remote_hosts_1[2]>"which vzctl"
Warning: Permanently added 'remote_hostname_1[2],remote_host_IP_1' (RSA)
to the list of known hosts.
/usr/sbin/vzctl

but vzmigrate still fails with the error message listed above.

Any thoughts,hints,ideas on that issue?

Thanks in advance,
Nikolay.

Hello.

You can define LC_ENV in env_keep variable in sudoers file. In this case
root PATH will be saved during sudo-session.

The issue you are describing is believed to be fixed in vzctl 3.0.26.3 which
was released 2 days ago :)
