Multihomed openVZ server

Are there any guidelines on setting up a server that is multihomed?   I want to have VPS on different networks.  The two networks are partitioned by a firewall and the fact that ip_forward is turned on is I believe causing issues.  Doubtless there is some deep routing foo that can be applied - I'd appreciate any pointers.

Alastair

VT in processor + chroot

Hi all,
I am discovering OpenVZ.
As far as I know, it's OS level virtualization.

That would mean it doesnt care wether the CPU is VT or not.
Am I right?

Secondly, what would be the main difference between a chroot and openVZ?
The quotas control? (RAM allocation, and so on...)
Am I right? What else?

Thanks for your answers?

VT or SVM is not used/needed with openvz

Independent networking and mount points. A guest in Openvz looks like
a different machine.

Re: VT in processor + chroot

Hello Rakotomandimby Mihamina,

>>That would mean it doesnt care wether the CPU is VT or not.
Am I right?
Yes. Thats right. 

>>Secondly, what would be the main difference between a chroot and openVZ?
The quotas control? (RAM allocation, and so on...)

chroot would simply make some directory your root directory i.e from where
on your path of commands/executables shall be resolved.  OpenVZ offers you
a multiple execution environment which means you can run a bunch of processes
inside this environment. In very simple words this gives you isolated execution space.
For eg:  If you have two containers and some processes running in both of them (say) then the processes between these two containers cannot see each other.  So you cannot send for eg: a kill signal from a process in one container to a process in another container.

OpenVZ offers checkpoint/restart/migration of these processes by
checkpointing/restarting/migrating the containers these processes run in.
Please read the documentation available on http://wiki.openvz.org/Main_Page
http://download.openvz.org/doc/openvz-intro.pdf.

You can also try to install OpenVZ in VMWare (or any other virtualization environment of your choice). You can compile the kernel and try out OpenVZ. It will just take like 30 mins to try it from scratch :)

Best Luck !
Warm Regards,
Surbhi.

openvz , iptanbes, squid reverse proxy, web access

hi there i have setup my vz system, so that i port forward port 80 to a container running squid which reverse proxies to sites running inside openvz containers via their virtual ip. my issue is and has been changes i make either block full access to the web from each container or they cannt access any site via their domain running in their own container or another one even though i have properly setup the iptables post routing to allow internet access. My problem seems to be when the containers are trying to access the site it gets stuck at squid and cant get reverse proxies properly, how is it possible to set up the iptable configuration so they request the site domain via the public ethernet etc.

this is my problem

* About to connect() to domain port 80 (#0)
*   Trying myip ... Connection refused
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host


and requestion google is fine

*   Trying 66.102.11.99... connected
* Connected to www.google.com (66.102.11.99) port 80 (#0)
> GET / HTTP/1.1

This issue is breaking a system requiring access trying to load in some feed from another system. 

any ideas ?

Pre-created Fedora 11 OS Templates available in contrib

Greetings,

Just wanted to mention that I uploaded to contrib two new OS Templates today for Fedora 11 since today was its
release day:

http://download.openvz.org/template/precreated/contrib/

fedora-11-i386-default-20090609.tar.gz          09-Jun-2009 13:26  170M  
fedora-11-i386-default-20090609.tar.gz.asc      09-Jun-2009 13:26  189   
fedora-11-x86_64-default-20090609.tar.gz        09-Jun-2009 13:30  166M  
fedora-11-x86_64-default-20090609.tar.gz.asc    09-Jun-2009 13:30  189

Basically I created a Fedora 10 OS Template, updated it to current, and then upgraded it to Fedora 11, did the
customary cleanup, and then tar.gz'ed them up.

Questions and comments are welcome.

TYL,
--
