I virtualized a hardware node according to the wiki. I used the latest RHEL based openvz kernel (2.6.18-53.1.19.el5.028stab053.14) and (2.6.18-53.1.13.el5.028stab053.10). When I load the virtualized vps i get the following in dmesg and a very hight server load.

could i have forgotten something to do in the physical to virtual migration? Or is this a kernel problem? Can it be hardware or driver related? I tried the fixes in the forum and did
echo 512 > /proc/sys/net/ipv4/tcp_max_tw_kmem_fraction
and that did not fix anything.
