Slow LXC starting time

[debek]

Hi!
When I try to run my LXC machine it takes about 5min when it will be available.
Do you know what can be wrong and why?

Hi,

what is the config for LXC container? pct config <VMID>

 

[mira]

Have you checked the syslog/journal in the container? Perhaps network (often has a 5min timeout) or something else is hanging on startup.

My syslog showed me a problem

Do you have any idea why I have this problem? But finally, everything works fine.

 

[mira]

Did you configure DHCP for IPv6 without a DHCP server running in that network?
Please provide the config of that container (pct config <CTID>).

 

[debek]

Thank you for your reply. Yes, it is a problem with ipv6. I need to configure it on my Mikrotik router.
