You probably configured your kernel incorrectly (missing initrd, device of filesystem drivers?). Try installing a pre-built kernel image instead, it's more likely to be bootable without problems. regards, -- Marcin Owsiany <[EMAIL PROTECTED]> http://marcin.owsiany.pl/ GnuPG: 1024D/60F41216 FE67 DA2D 0ACA FC5E 3F75 D6F6 3A0D 8AA0 60F4 1216 "Every program in development at MIT expands until it can read mail." -- Unknown ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
[Users] any openvz-on-xen users?
As you might know already, since 028stab045 kernel from RHEL5 branch we support Xen architecture. That basically means one can run OpenVZ kernel on top of Xen hypervisor, in both DomU and Dom0. My quick question/request is: if you are using it (or want to), please let me know. Regards, Kir. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

Try installing a pre-built kernel image instead, it's more likely to be bootable without problems. Where can I get the pre-built kernel image? http://debian.systs.org I suppose. The wiki page you referred gives info about how to configure this. After install the kernel-patch, the system compiled the kernel and created the optional item in /boot/grub/menu.lst. What I had done is under the instructions of openvz wiki. Is there something wrong? These instructions are OpenVZ-specific, i.e. they only recommend openvz-specific options in kernel config. Any other kernel config options (there are a lot of) are on your own. One simple example of what could be done wrong -- if you haven't enabled support for SATA disks, and your HDD is SATA you are in trouble. So, if you are not experienced in kernel recompilation, you'd be better of with precompiled kernel. Thanks in advance. Hope that helps, Kir.

[Users] Unable to start VPS on Debian Etch
I am unable to start a VPS under a Debian Etch host. I can't find any useful message as to why it's failing to start the VPS on /var/log/vzctl.log. The machine is a dual quad-core Xeon (Intel(R) Xeon(R) CPU E5345 @ 2.33GHz). I used the debian-4.0-i386-minimal.tar.gz template from openvz.org to create the VE. Here's what I get when I try to start the VE: michael:/etc/vz# vzctl --verbose start 101 Unable to open /usr/lib/vzctl/modules/: No such file or directory Starting VPS ... Mounting root: /srv/vz/root/101 /srv/vz/private/101 VPS is mounted VPS start failed Running: /usr/sbin/vzquota stat 101 -f VPS is unmounted Kernel: Linux michael 2.6.18-openvz-13-39.1d1-amd64 #1 SMP Sat Sep 29 15:02:55 MSD 2007 x86_64 GNU/Linux I grabbed the kernel from http://download.openvz.org/kernel/debian/etch/ and put it in place manually because the package wouldn't install because I am running a 32-bit userland, but wanted the 64 bit kernel.

Re: [Users] Unable to start VPS on Debian Etch
plz check that OVZ tools: vzctl and vzquota are 64 bit versions as well.
looks like they are 32bit. they have to be of the same arch as kernel.
Thanks,
Kirill
