Virtuozzo Routed Network
Dec 10, 2008
I have one question about configuration Virtuozzo or OpenVZ. I have for example 90.90.102.192/26 subnet where Virtuozzo host (Linux) machine (IP 90.90.102.195) resides.
Now I have new subnet (90.90.100.0/24) routed to my default gateway 90.90.102.193. What to do and how to route these new IP addresses to my Virtuozzo VPS clients?
----------------
90.90.102.193 - my router
----------------
|
|
----------------
90.90.102.195 - virtuozzo host
----------------
|
|
----------------
90.90.100.0/24 - vps clients
----------------
Its better routed or bridget network?

So I have a bunch of IP's that are routed a VLAN a bunch of machines are on which is great. They can be put on any machine, but the problem right now is it is taking up to 4 hours for them to route from one machine to another (I am doing it one IP at a time not by blocks)
The process of adding and removing ip's is being done through cPanel's WHM. The reasoning for this is due to ARP on the router for the specific IP. This is a big issue if you're looking to migrate IP's from one machine to another that contain customers this is a long wait.
Now from the datacenter I was told you're going to need to wait the 4 hours for the refresh. Now what's strange is I was also told virtuozo apparently can swap ip's to other boxes without issues because it apparently it has a mechanism in place to release the ip's from the router/switch by communicating to it so the old arp is gone. I also asked someone using OpenVZ and they said theirs was instant as well to swap between boxes.
So is there a special command I should be issueing to get the router/switch to drop the IP instantly? Or any suggestions on how to get this to be more instant than ~4 hours for an IP to route to the correct machine.

My colo tech guy told me that it's possible to route two ip addresses to one server. The reason why I want to do this is to have one ip be the main domain and the other be the static domain. Both domains goto the same server but there are two server daemons (apache and lighttpd) installed on the server. Each server listens on one ip (so light = static domain ip and apache = main domain ip).
I have everything setup, but I am just wondering that will this work with the routing setup? Can one network interface card handle both ips?

I was just curious as to how virtuozzo manages the cpu usage. Do all VPS's just use as much cpu as they can at one time or is there a min and max limit?

We're currently using virtuozzo and have been but we are thinking of starting a Xen server as our techs have the technical expertise to manage a Xen server. I'm just wondering whether we would be better off with this or not, compared to Virtuozzo.

I installed Apf on Virtuozzo VE, which went well until I enabled it. I could not access Plesk installed on the machine, then I realized it was listening to port 8880 from the Service VE as well as 8443. Enabling 8880 in the common ports solved the problem, but I only want it blocked for everything BUT the Service VE.
I looked in the manual and the section that discusses adding custom rules for aliases only has a header and does not have any description.
Anyone know how to block port 8880 to the world but allow 8880 to a particular IP?

We are having an issue when trying to cache Fedora Core 10.
Code:
vzpkg create cache fedora-core-10-x86_64
Creation OS template cache for fedora-core-10-x86_64 template
Error: Python directory not found in /vz/pkgenv/rpm46x64
Error: Can't find environment directory /vz/pkgenv/rpm46x64: No such file or directory
The only recent changes that have been made is the Hostname. Before making this change, I was caching OS templates like it was christmas.

Which one do you prefer more and why?
Virtuozzo is very expensive while OpenVZ is free and it is somehow another Virtuozzo, but made simpler?

I've read that Virtuozzo 4.0 supported ipv6. I'm having problems finding anything to help setup the node for ipv6. I can't anything on the web except for some people talking about how to disable ipv6. So I was just wondering if anyone else has seen anything.
Edit: I don't think I posted in the correct section. Opps. Could a moderator move this to the right section?

I have an main server which has ssh configured that it connects to main vz server without password.
How to connect to all vz servers and lets say do command cat /etc/resolv.conf and send result to my email address?
I believe it should be something like this:
ssh server1;vzlist ..;vzenter 1$,2$;cat /etc/resolv.conf | mail bla@blah.com....;ssh server2;vzlist ..;vzeneter... and so on so forth.

I got a Virtuozzo VPS couple a days ago and I am having some problems with it. I can't get a hold of the host because he/she is "migrating" company website at the moment.
VPS OS - Ubuntu 8.04 32-bit
(Initially was 64-bit but I can't even get SSH to work. The host reloaded with 32-bit.)
Initially I was getting some permission problem on /dev/null for regular users. I fixed that with following and stick it in /etc/rc.local
chmod go+rw /dev/null
Now I can't get screen to work. It said something about "No More PTYs.".
$ ls -l /dev/tty*
crw-rw-rw- 1 root tty 5, 0 2009-04-14 14:55 /dev/tty
crw-rw-rw- 1 root tty 4, 0 2009-04-14 14:55 /dev/tty0
crw-rw-rw- 1 root tty 4, 1 2009-04-14 14:55 /dev/tty1
crw-rw-rw- 1 root tty 4, 2 2009-04-14 14:55 /dev/tty2
crw-rw-rw- 1 root tty 4, 3 2009-04-14 14:55 /dev/tty3
crw-rw-rw- 1 root tty 4, 4 2009-04-14 14:55 /dev/tty4
crw-rw-rw- 1 root tty 4, 5 2009-04-14 14:55 /dev/tty5
crw-rw-rw- 1 root tty 4, 6 2009-04-14 14:55 /dev/tty6
crw-rw-rw- 1 root tty 4, 7 2009-04-14 14:55 /dev/tty7
crw-rw-rw- 1 root tty 4, 8 2009-04-14 14:55 /dev/tty8
crw-rw-rw- 1 root tty 4, 9 2009-04-14 14:55 /dev/tty9
(I have "chmod go+rw /dev/tty*" in /etc/rc.local too.)
What can I do or what can I have the host do? I rely heavily on screen for all admin works and I need it to be working. Thanks for your thoughts!

Has the VZ bug where "doing a Windows Update on a node applies it to the whole server and then reboots the node" been fixed yet. We offer Linux VPS using VZ and was going to use it for Windows too but when I heard that I put the plan on hold.

which one would you recommend?
because Virtuozzo is charged, i think it may more easy to manage for admin and user,
xen has it's own feature than Virtuozzo,but i feel hypervm is not very friendly to use ( my personal feeling)

We have a client on a VPS (Virtuozzo) that is failing PCI Compliance through McAfee as the port for the "power panel" in Viruozzo uses week SSL encryption.
Since we can't block the port (as users need to be able to access it) does anyone know how we can possibly upgrade that or change things so that it will pass compliance?
All other ports on the server are fine, but the port 4643 keeps failing under the ScanAlert scans:

I would like to know which clients would prefer Virtuozzo over HyperVM. Lets say there is a company offering Virtuozzo on there servers. However, there is another company offering HyperVM for a cheaper price. Neither companies are overselling. Would you be willing to pay the extra money for Virtuozzo? Or would you be happy with OpenVZ and HyperVM.

Does any dedicated server provider give a Virtuozzo license with unlimited VEs? I've noticed that most of them give 3, 10, or max. 100. Do you have any idea why wouldn't they give a license for unlimited VEs and why are they restricting the number of VEs that we can create on a server since, as far as I've understood, Viruozzo provides license considering the CPU no.s, but not the number of VEs.

I found out that once I enable CSF it will automatically enable the virtuozza firewall with the default policy "drop anything".
My provider updated all VPS and they updated virtuozza to "parallels infrastructure manager" ..which is still virtuozza but a little bit different.
I double-checked it and anytime I restart csf to apply the new rules it will add the default policy "drop". I can change it back to default accept but obviously if I restart again it will block me out.
This is pretty strange. Once CSF is disabled and I use Virtuozza FW only everything is working.

I'm colo'ing, so this wouldn't be shared with anyone else.
I'm looking at using iscsi with Virtuozzo Containers, and while the setup for the hardware nodes seems fairly straightforward, can anyone comment on their own experiences using iscsi with VZ?
Did you find your experience reliable? Slow? Any information will be useful.
Also, did you have a hard time setting things up? Or did VZ just manage everything as if it was still on a single server?
