I'm having issues installing a new kernel onto my openvz container. My provider told me they enabled ipsec on the host openvz machine and that I have to compile a generic kernel. I've tried building 3.16.3, appeared to have finished creating the kernel image, /boot shows image files but I am not sure what step to do next to install it?
i've tried 'mkinitramfs -o initrd.img-3.16.3 3.16.3' that did not appear to install it.
i have also tried installing generic .deb kernel builds of 3.16.3 and it appeared to successfully install the .deb files but when I rebooted the kernel still says 2.6.32
I'm trying to setup ipsec however pluto appears not to bind to a public IP.

@RyanGrant If you are using Debian, I strongly recommend building a binary deb of the kernel image. Much easier to keep track of it then.
@RyanGrant which kernel is booted depends on your grub entry. Paste your current grub entry into your (hypothetical) question.
@RyanGrant ask your questions on the site, not here. you can point to them from here if you want.
@RyanGrant if you want further information about building binary kernel debs, there are a couple of ways to go. if you want further information, you can ping me.

The answer warwick provided was correct. Than the question was changed so that that answer doesn't make sense anymore. A new question should be posted.
I rolled back this question to its original version. Once you receive an answer that solves your initial problem, accept it and then post a new question to pursue it further. Editing the original one in this way renders the existing answers irrelevant. — terdon ♦36 secs ago
Since RPM 4.7, there has been the ability to specify that a file in an RPM package should be installed with capabilities(7) set (via %caps). See http://www.rpm.org/wiki/Releases/4.7.0#POSIX.1edraft15filecapabilities for details.
Is there a similar feature for Debian packages?

@Ramesh - I find them too from time to time. Just bring them to our attention, house cleaning is a never ending task 8-)
The older things were viewed in a slightly different light too. ppl were happy to have any questions so things were allowed more so than they are now IMO.
For the purpose of performing permission checks, traditional UNIX implementations distinguish two categories of processes: privileged pro‐
cesses (whose effective user ID is 0, referred to as superuser or root), and unprivileged processes (whose effective UID is nonzero).
Privileged processes bypass all kernel permission checks, while unprivileged processes are subject to full permission checking based on the
process's credentials (usually: effective UID, effective GID, and supplementary group list).
Until now I only rolled back my own Answer if I felt this was wrong. Some OPs obviously take a bit more to see the point than others. @terdon I will apply the sharp stick directly to the OPs. There is no need to drive moderators to extinction.
@Ramesh @terdon - the original command that I used did not include either the -0 or --print0. A user left feedback that I took at face value but did not test, they said to add a -0 so I did. The origin of that command was to copy files that had no spaces in their names, I've now realized that it's not 100% reliable, I'll update the command, and thanks for pointing out the error!

I remember that conversation w/ him about it. I've often wondered why after a period of time if I as the A should be able to UV my own works. I've used them more times than I care to admit. This is a big reason why I've almost exclusively produced work here rather than on my blog.
It's easier to find and maintain it here and it's always available.

If no package matches the given expression and the expression
contains one of '.', '?' or '*' then it is assumed to be a POSIX
regular expression, and it is applied to all package names in the
database. Any matches are then installed (or removed). Note that
matching is done by substring so 'lo.*' matches 'how-lo' and
'lowest'. If this is undesired, anchor the regular expression with
a '^' or '$' character, or create a more specific regular
expression.

@Gilles I think it has already been covered somewhere. And I remember you answering a similar question once. If you don't want to take the time, it's Ok.
@slm Um, I forget what this question is about. Are you saying there is something to add to it?
Your answer, I mean?
@terdon I don't think `apt-get -s purge "^apt-*" is right, and I suck at regexes. can never keep them in my head. why would it match 'aptitude-doc-cs' ?
searching with YUM
You generally don't use any regular expressions (globs) when searching with yum search since the command search is already looking for sub-strings within the package names and their summaries. How do I know this? There's a message that tells you this when you use yum search.

@FaheemMitha I don't believe grub is installed on the VPS, the /boot/ folder has no grub folder: root@shiftmy:/boot# ls System.map-3.16.3 config-3.16.3 initrd.img-3.17.0-031700rc4-generic System.map-3.16.3-031603-generic config-3.16.3-031603-generic vmlinuz-3.16.3 System.map-3.16.3.old config-3.16.3.old vmlinuz-3.16.3-031603-generic System.map-3.17.0-031700rc4-generic config-3.17.0-031700rc4-generic vmlinuz-3.16.3.old
So, any idea how it is doing the boot thing. I suppose grub isn't actually necessary, but I've done anything without it. Well, once upon a time there was LILO...
I should say I've never done anything without a boot manager.
@RyanGrant the kernels are all from binary deb packages?
@FaheemMitha yes I don't believe it has any boot loader, how do openvz systems work for that? The 3.13. kernels were from generic source, the others .16 and .17 were from deb packages.
@FaheemMitha yes it is within a openvz system. I told the VPS provider that the ipsec shows kernel issues, they followed this guide to enable ipsec on the host machine:openvz.org/IPsec I then read it and told them it sounds like it needs to be on the HOST machine not the VPS (the fix), they then realized that and did the fix. I tested and it still failed, they then stated to build source for kernel with ipsec support and let them know once I'm done that if that fixed it.
@RyanGrant Ok, so you want you to hand over a kernel deb with ipsec support? They could not do it themselves? That seems a bit pathetic. Am I understanding you correctly.
Ok, in that case, what you need is to build a deb, and test it separately. On another machine.
@FaheemMitha yes it seems they are trying to get me to build my own kernel when I believe they should be building it on the host machine since I have also questioned if a container can install a new kernel since I cannot seem to find any boot loader.
@RyanGrant ok. well, test it separately. building a kernel deb is a whole separate project, but a good way to go for various reasons. I would say a very good to go.
If you are going to hand it to someone else, then that is a doubly good reason.
@RyanGrant Um, not following, they told you to rebuild the kernel inside your container? What is the point of that? Your container can't boot it.
@FaheemMitha problem is I don't think I should be building the kernel at all since I don't know what requirements their host machine requires and what their other clients require of the kernel. so they should really be updating it.
@FaheemMitha I have tried installing ubuntu 12.04 and 14.04 as a container, both containers appear to use same kernel. Linux shiftmy 2.6.32-042stab084.12 #1 SMP Tue Nov 26 20:18:08 MSK 2013 x86_64 x86_64 x86_64 GNU/Linux
Unless they are using proprietary kernel modules (a dodgy concept) I don't confidentiality should be an issue.
@RyanGrant That's because they do. Said so already. See any documentation, e.g. wikipedia.
So, anyway, again, I recommend you build your own binary deb based on their config. If they won't give you the config and kernel version, you have a problem.
In which case I suggest you switch to a provider that is more clueful.
@FaheemMitha I am not too familiar with the background of openvz setups but from all of this it does appear the host machine hosts the kernel then containers get loaded and run off the hosts kernels
