Hello,

I am encountering an error with KVM VPS' from the virtualizor interface. I have two servers (one is Master - localhost and the other is the Slave - public IP).

I have the following in the log for the VM after I create a new KVM VM (/var/log/libvirt/qemu/v1004.log):


Code

Moreover, I have some errors with the libvirtd service. I tried restarting the libvirtd service, but it started showing errors (journalctl -u libvirtd.service):

The curious thing is that on the Slave node everything works well and the problem only resides on the master server.

Can anyone point me in the right direction to get this solved?

Thank you.

Hello,

It seems like there was something stale with the systemd-machined service. According to the documentation, this service is " a tiny daemon that tracks locally running Virtual Machines and Containers in various ways.".

Of course, this was my case.

https://www.freedesktop.org/wiki/Software/systemd/machined/


Code
[root@server1 log]# systemctl status systemd-machined
● systemd-machined.service - Virtual Machine and Container Registration Service
  Loaded: loaded (/usr/lib/systemd/system/systemd-machined.service; static; vendor preset: disabled)
  Active: active (running) since Mon 2018-09-03 13:26:13 EEST; 3min 13s ago
    Docs: man:systemd-machined.service(8)
          http://www.freedesktop.org/wiki/Software/systemd/machined
Main PID: 26149 (systemd-machine)
  Status: "Processing requests..."
    Tasks: 1
  CGroup: /system.slice/systemd-machined.service
          └─26149 /usr/lib/systemd/systemd-machined

Sep 03 13:29:56 server1.mytld.com systemd-machined[26149]: New machine qemu-28-v1010.


After restarting the service, I could start the fresh VMs from the Virtualizor interface.

For anyone having the same error even after running "yum update" and restarting the libvirtd.service, dbus.service, tuned.service and systemd-logind services, try to restart systemd-machined and check if the session for each new VM is created in /run/systemd/system/ .

Good luck.
