As you suspected it works fine in 2.6.18-ovz-028stab051.1-smp - but I had problems with building that release from source Can you elaborate here? which is why I moved to the same kernel release as the base Ubuntu 7.04 was using as I had no particular kernel version preference. I do have other modules I need to compile up ...and here? - hence the issue with compiling which lead me to a newer kernel release. How 'stable' is the 2.6.24 release in terms of usage and known issues? It hasn't been tested much yet, and still in very active development. We have an intention to make it stable though. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
Re: [Users] IPv6 ??
Can you give us the the output of /sbin/ip a l and fgrep ADDRESS /etc/vz/conf/*.conf command run on your hardware node? Perhaps the problem is that the network interface(s) that is/are present on the hardware node do not belong to the same IP subnets as your VEs. Dmitry, Maybe it makes sense to add a warning if vz_get_neighbour_devs() returns an empty list, with the URL to a wiki page with long explanation?

NEIGHBOUR_DEVS=detect this option arived with vzctl version 3.0.22 when I was upgrading from 3.0.18-1dso1. After I removed that option and restarted HW node all IPv6 hosts get imediately online.

I've checked stty settings and they appear equivalent in both the VE and host. Have I missed enabling something which is mentioned in the documentation or is this a known issue?

[Users] RHEL3 and other older distributions
Looking to get RHEL3 working as a VE, and I believe there are various things that would have to be done to accomplish this. 1) Take a rpm 4.2.* src rpm and modify it in the same way as vzrpm43 and vzrpm44. 2) Create a new OS template to match the differences in rpm names and services enabled. 3) Install the new packages and create a template cache 4) Continue as normal Right now I'm working on part 1. I've noticed that in the vzrpm4x, for the sections that were added to handle building the python support there are references to a tool called alternatives. I suspect that this is used to setup how the different versions of python are used? Any ideas on where to get this tool, if it is available? Or what exactly it does? Also would the project be interested in having the results which should provide vzrpm42 packages? -- Regards, Darragh Bailey Systems Software Engineer Hewlett Packard Galway Ltd. +353 91 75-4674 Postal Address:Hewlett Packard Galway Limited, Ballybrit Business Park, Galway Registered Office: Hewlett Packard Galway Limited, 63-74 Sir John Rogerson's Quay Dublin 2 Registered Number: 361933 ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

I am not a guru in it, but I know it creates symlinks for different software, such as, in this case, different python versions. That way vzrpm can be built with different python versions which makes it possible to use on different host systems. If you do it just for yourself, you can remove this stuff from the .spec and just build your vzrpm with only one version of python. True, but I was thinking that the work that I'm doing on this might be of use to the project, and might be worth submitting back. So making the changes in a form which is useful to the project wouldn't be that much harder. Perhaps that is something I should take to the devel list? -- Regards, Darragh Bailey Systems Software Engineer Hewlett Packard Galway Ltd. +353 91 75-4674 Postal Address:Hewlett Packard Galway Limited, Ballybrit Business Park, Galway Registered Office: Hewlett Packard Galway Limited, 63-74 Sir John Rogerson's Quay Dublin 2 Registered Number: 361933 ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
