Hi,
We installed openvz on an HP DL 145 and whenever we use an openvz kernel, a simple I/O operation is about 10 times slower than using the centos stock kernel.
[root@vz1 ~]# date;vzdump --restore /home/ugob/vzdump-104.tgz 105;date
Wed May 23 10:24:13 EDT 2007
extracting archive '/home/ugob/vzdump-104.tgz'
extracting configuration to '/etc/vz/conf/105.conf'
restore successful
Wed May 23 10:35:54 EDT 2007
Normally, this takes less than 1 minute on a stock kernel. I also tested on a less powerfull machine, and it also runs in about 1 minute.
Kernels tried:
2.6.18-8.el5.028stab031.1 #1 SMP Sat Apr 28 00:38:07 MSD 2007 i686 athlon i386 GNU/Linux
ovzkernel-PAE.i686
Also, the system remains slow after this operation... It looks like processses remain hung, like this one:
root 10809 0.0 0.0 1568 468 ? Ds 10:30 0:00 /usr/lib/sa/sadc -F -L 1 1 /var/log/sa/sa23
(it is now 10.39 and this command should take less than 1 sec to execute...)
Here is the output of lspci.

. Will give you feedback ASAP.
) only because it's a bit more convenient for the support if users use officially released kernels. So this requirement is not strict.
