vzpkg/vzyum are not a requirement for OpenVZ to function, they are optional.

More to say, as you can see from [1], vzpkg and vzyum are
unsupported/unmaintained. Users are expected to use
precreated templates available from [2]. If you are
not satisfied with available precreated template, you can
repack those, or create your own from scratch.
There are some articles on wiki that tells you how to do that,
see [3].

Hope that helps.

The neat thing is that your [3] link refers to using vzpkg, which is
useless as you say.

At one point there was an excellent utility called vzpkg2 which solved
the problems with vzpkg. Alas, it seems to have disappeared. I still use
it.

	I confirm this is working no trouble..

	Note:
	If you have container dual stack (IPV4,IPV6)
	but NOT all container on the IPV4 subnet,
	you need to define a second bridge on
	the host (with the IPV6 number) and container
	with a second interface (eth1) attached to 
	the host second bridge.

	Having the container set with one interface
	carrying both IPV6+IPV6, but not all the container
	on the same IPV4 subnet make the routing quite
	unreliable.

It's probably already enabled.  If it's enabled in the host node it's
going to be enabled in the guest.

Run ip -6 addr ls in the guest.  You should see something like this:

[root <at> yelm ~]# ip -6 addr ls
13: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
    inet6 2001:4830:3000:8200:204:8ff:fecd:263d/64 scope global dynamic 
       valid_lft 2591958sec preferred_lft 604758sec
    inet6 fe80::204:8ff:fecd:263d/64 scope link 
       valid_lft forever preferred_lft forever
15: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

You see anything with inet6 addresses, you've got it enabled.  It may
not be configured, but you've got it enabled.

Although I am not using the RHEL6 kernel I have used a 64 bit 2.6.32
openvz git kernel for some time (>1 year?)  with ext4 without a single
problem.

How-to upgrade a Ubuntu-8.04 LTS VE to a 10.04 VE?

Greetings:

I run Debian-5 (Lenny) as my OpenVZ host OS with 3 Ubuntu-8.04 LTS VE's 
and a Debian-5 VE.

Question: I'd like to upgrade the production 8.04 VE's to 10.04.

Can this be done?

I tried searching but couldn't find a definitive (recommended) procedure 
for performing a "distribution upgrade" to production VE's.

Is there such a procedure?

Thanks.
Michael
