Okay, can someone with a bugzilla account please confirm and create a
bug with this one:
Kernel (uname -a): 2.6.32-042stab039.11 as x86_64 installed on CentOS 6 HN
steps to reproduce:
- use a Ubuntu 10.04 i386 (32 bit) template and create a VE
- load ipt_recent in vz.conf
- start the VE and use something like this "iptables -A INPUT -p tcp
--dport 25 -m conntrack --ctstate NEW -m recent --name SMTP --set"
inside the VE
- exit the VE and execute vzctl stop <VE-ID> at the HN
The result is the following kernel panic
