[Users] VMs startup problem

[Nerijus Kriaučiūnas]

Hi,

I am experiencing problem with OpenVZ 7 during the physical server reboot.

When I have more than 20 active VMs on my host with "--onboot yes" flag 
enabled, only the first ~17 VMs start correctly, others never start up 
and their services can be seen as failed.


Output from systemctl:

/● vz_74739fed-2da8-4fa8-8cf7-ed8f3bd1de46.service loaded failed 
failed    Virtual Machine {74739fed-2da8-4fa8-8cf7-ed8f3bd1de46} service/

systemctl status vz_74739fed-2da8-4fa8-8cf7-ed8f3bd1de46.service:

/Jan 06 15:01:42 Host systemd[1]: Starting Virtual Machine 
{74739fed-2da8-4fa8-8cf7-ed8f3bd1de46} service...//
//Jan 06 15:01:42 Host prlctl[3055]: Login failed: Unable to connect to 
the server. The maximum number of simultaneous logon attempts has been 
reached. Try to connect to the server later.//
//Jan 06 15:01:42 Host systemd[1]:

code=exited, status=255/n/a//
//Jan 06 15:01:42 Host systemd[1]: Failed to start Virtual Machine 
{74739fed-2da8-4fa8-8cf7-ed8f3bd1de46} service.//
//Jan 06 15:01:42 Host systemd[1]: Unit 
vz_74739fed-2da8-4fa8-8cf7-ed8f3bd1de46.service entered failed state.//
//Jan 06 15:01:42 Host systemd[1]: 
vz_74739fed-2da8-4fa8-8cf7-ed8f3bd1de46.service failed./

All VMs boots up only after restarting prl-dip.service for two/three times.

I have tried to change VE_PARALLEL value in /etv/vz/vz.conf, but without 
success.

How can I fix this issue?

Any help is appreciated.


Regards,

Nerijus
