Hi!
After last upgrade (yestarday), after long war with bootup srv I run node and...
When node startup, all VPS on debian don't get network (of course centos work corect), but when I add from CP additional IP (1 per VPS), all go up. Next - reboot - and again I must remove/add IP's.
this is iptables -t nat -L && iptables -t filter -L && iptables -t mangle -L after 'action'.

of course before action is this same, only without static.88-198-103-132 and static.88-198-103-134.

openvm reinstalled about 5 times (this same final)

Any solution?

Kernel -> 2.6.18-194.26.1.el5.028stab081.1
vzctl -> 3.0.26
debian -> downloaded, selfbuild
versions ->
debian-5.0-amd64-minimal.tar.gz
debian-5.0-i386-minimal.tar.gz
debian-5.0-x86.tar.gz
debian-5.0-x86_64.tar.gz
debian-5-i386-modernadmin-minimal.tar.gz
debian-5-x86_64-modernadmin-minimal.tar.gz

I slowly move all debian vps to centos, but it's strange Wink

best regards

SOLVED: problem is vzctl debian scripts (backported from 3.0.25.2 and everything works fine).

I have the exact same issue: after upgrading the kernel to version 2.6.18-194.26.1.el5.028stab081.1 every debian based container has an empty routing table (connect: Network is unreachable).

route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

NOTE: Anyother redhad/centos/fedora container works just fine...

Also, after adding/removing and IP address from the container the routing table looks ok.

 route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         0.0.0.0         0.0.0.0         U     0      0        0 venet0

But, after restarting the container, the problem persists.

vzctl version 3.0.26
2.6.18-194.26.1.el5.028stab081.1 x86_64
CentOS release 5.5
