opennode-tui gives error on Create VM

[TAfirehawk]

I am running CentOS 6.2 with OpenVZ kernel 2.6.32-042stab045.1 on x86_64 patched in after OpenNode script was used.  I did "yum update opennode" to get the latest opennode-tui.

This is my third install of OpenVZ/OpenNode but this time I can't get a VM created without the following error.  I added the template in the template cache and the files show up in /storage/local/openvz and /unpacked.

Code: [Select]

Hi,

could you please check two things:

1. Is libvirtd running? service libvirtd status

2. Please, post output of: /usr/sbin/vzlist -ovpsid -H

thanks,
Ilja

1. libvertd is running

2. "Container(s) not found" is the output


I don't know if this matters and I have posted about this vzkernel-firmware conflict on OpenVZ's forums, but there seems to be some issues with the latest kernels.

Code: [Select]

Warning: RPMDB altered outside of yum.
** Found 3 pre-existing rpmdb problem(s), 'yum check' output follows:
kernel-2.6.32-220.el6.x86_64 has missing requires of kernel-firmware >= ('0', '2.6.32', '220.el6')

I got that error when doing "yum install vzdump"

Another thing I noticed from my previous install is the directories have changed.  Previously the template cache was /storage/templates/openvz with "deploy" inside and now it is /storage/local/openvz with "unpacked" inside.

I have tried copying all the template files between these folders but I am still getting the same error.  I know last time I had to manually wget the template files because the opennode-tui wouldn't download them properly....but this time none of my tricks are working.

Directories are ok, there was a problem with them for some time, as we've added support for multiple storage pools (e.g. on local disk and on a shared FS), so path had to be changed a bit to reflect that.

I've reproduced the problem, it is caused by a wrong handling of the cases when there are 0 CTs available when running opennode-tui. Working on a fix.

Thank you for the super-fast response.

Ok, fixed RPM is in the repository (opennode-tui-2.0.0-1.on.20120102161505.x86_64), just update the package and it should work.

Thank you for reporting this issue, a pretty stupid bug, not sure why it wasn't caught before. It seems that libvirt's 0.9.x branch python wrapper behaves in a slightly different way than the one we had before (0.4.x), I've changed detection of existing openvz CTs to use openvz cli directly, instead of going through libvirt.

Fixed

I got to the VM settings now, thanks for the super-fast help.
