it depends on how much work has to be done. OVZ7 has some advantages, but of 
course there are other possibilities, depending on the requirements.

It has improved in the last year or twi and with LXD it even got a nice REST 
API. Also the nasty systemd bugs have been fixed in the meantime.

I once also build a OpenVZ 7 kernel for Debian as deb package with the standard 
procedure for building Debian custom kernels. I failed with getting all the 
tools up and running. Debian would be the only option for me to give OVZ 7 
another try.

Yes, though I'm not using openvz precompiled kernels, I compile

my own kernels and package them in .deb, then install and as part of
postinst it runs update-initramfs normally.

Re: [Users] OVZ6 boot freeze on Debian 8

2017-07-10 Thread Narcis Garcia 
StalkR:
1. Do you mean OpenVZ boot files could be directly copied from a Debian
8 to a Debian 9?

2. Do your OpenVZ kernels upgrade properly on Debian 9? How did you
solve the initrd images generation as Vasily talks about?

Re: [Users] OVZ6 boot freeze on Debian 8

2017-07-10 Thread spameden 
@Stalkr, wow, nice work!  I think I've tried OpenVZ7 kernel some time ago
but didn't have any luck.

Compiling yourself is a hassle althrough unless you make an automatic
repository which will be updated after the new release is pushed.

Is it really worth maintaining yourself the kernel and userland tools to
get OpenVZ working?

Isn't LXC still not production ready?

Re: [Users] OVZ6 boot freeze on Debian 8

2017-07-10 Thread StalkR 
I've been running OpenVZ legacy on Debian 6/7/8 and now 9
(hosts+containers), works fine. Note I compile my own kernels.
I recall I had a similar boot freeze in Debian 8, and fixed it by
installing sysvinit too, but I never copied the inittab and instead choose
the secondary boot menu (setting init=/lib/sysvinit/init) and since then it
worked. I upgraded to Debian 9 and still works fine (hosts+containers). Try?

And something to be aware: over time I noticed more problems with
systemd/openvz: systemd-init not cleaning zombies after a while,
systemd-tmpfiles boot lockup, systemd-logind timeouts for ssh in
containers, etc. so recently I removed systemd from a Debian 9 host (start
with this ) and
so far so good, I need to do it on more hosts and try with containers too.

I'm also in the process of trying OpenVZ 7 with Debian, so far I have a
working kernel and I'm trying to get the userland tools working...

Re: [Users] OVZ6 boot freeze on Debian 8

2017-07-08 Thread Narcis Garcia 
Pre-requisite for a Debian 8 (jessie) host is:
$ apt-get install sysvinit-core sysvinit-utils
$ cp /usr/share/sysvinit/inittab /etc/inittab

Then OpenVZ Legacy seems to work perfectly.
(For Debian 9 it doesn't seem to be enough)
