/sbin/ip6tables-save' failed: exit code 1

[Amori]

Hello,

Ordered a new dedicated server and installed Proxmox 3.3.20.
I have transferred some VM's and then I noticed some connection failures when I restore VM's. It hangs at 20% then the web gui get unavailable for a while.... I restarted the apache several times via ssh until I was able to login via web GUI.

However I see the vm is restored and the scenario repeats again next vm restore. I checked in the syslog and I saw a lot of these errors
/sbin/ip6tables-save' failed: exit code 1



Can someone help me??

I need to know why I got this error and why my proxmox is slow when I restore vms.

We do not use apache at all, so I wonder how restarting apache helps. Please can you post your /etc/hosts file?

Actually it did not helped me.

When I restore a VM... the server get unavailable for a while(1-3 hours) until the vm is fully restored.

Other proxmox server, the restore process take max 20 minutes.

I have no idea why ip6tables-save fails, sorry.

Concerning performance, what kind of disk subsystem do you use?

And what is the output of

# pveperf

What kind of disk is that? FSYNCs are simply too slow.

It's happening for me too. This has only been happening for the last updates: It didn't work like this before.

# service pve-firewall stop

seems to solve it. In order to avoid it from running on startup next time, you can instal rcconf and untick pve-firewall service.
Also, if you need a firewall, install a third party one, instead of the pve. I personally use shorewall complete with NAT bridging and several features that the pve-firewall didn't have.
