[SOLVED] installing slackware64-14.1 in openvz container

Hello SlackWorld:

I heard about hostus.us from this thread, and, wanting a slackware VPS, I signed up for unmanaged VPS, logged in, chose rebuild and selected the slackware64-14.1 minimal template. Once it was done and I could ssh into the VPS I did the following:

I created a directory to contain slackware64-14.1 tree, and then used rsync to obtain a local copy of the slackware tree, because I use many packages that didn't come with the minimal template, such as zsh, emacs, etc.
I don't want to mess up my virtual container, so I thought I would play inside a fresh chroot. I created a directory (myroot) for the fresh chroot, and then used i
Code:
```
nstallpkg --root myroot a/*.t?z ap/*.t?z e/*.t?z
```
, and did this for everything except kde, x, xap, and y, which I don't need because I don't plan on running X inside this container.
I did the
Code:
```
mount -o bind /proc /myroot/proc
```
and the same thing for /sys and for /dev, and then I attempted chroot and received error:
Code:
```
root@lax:~# chroot /myroot 
FATAL: kernel too old
```

Hmm... so I tried to learn about the kernel:

Code:

root@lax:~# uname -srov
Linux 2.6.32-042stab113.11 #1 SMP Fri Dec 18 17:32:04 MSK 2015 GNU/Linux

. The same command, on any other slackware64-14.1 system I have installed yields

Code:

uname -srov
Linux 3.10.17 #2 SMP Wed Oct 23 16:34:38 CDT 2013 GNU/Linux

I concluded that the openvz container is running an old kernel... I check /boot and it's empty.

Is there a way to get linux kernel 3.10.17 functionality out of the hostus.us slackware vps?

Jack, at hostus.us, answered my question:

Quote:

OpenVZ is locked at a 2.6.xx custom kernel which has a lot of security and features backported from newer kernels, but not all however. We are unable to upgrade the system kernels of our nodes until openvz releases and moves to a more modern kernel base.

So, I installed slackware64-13.37 into myroot, and chroot works just fine!

In fact, asterisk, lisp, mysql, and the other services I run worked great under 13.37, so I will still not have any issues with hostus.us -- the speed of mirroring slackware was phenomenal compared to DSL at home: like I blinked my eyes and rsync was done.

cheers.
