If i do (Fresh PVE Install with all Updates):

# pve-firewall status

ipset v7.10: Cannot open session to kernel.
command 'ipset save' failed: exit code 1

...and check this
# pve-firewall compile

ipset cmdlist:
ipset v7.10: Cannot open session to kernel.
command 'ipset save' failed: exit code 1

... and this
# ipset save
ipset v7.10: Cannot open session to kernel.

What can i do, thanx for help!
