HyperVM Openvz... IP's Won't Work After OS Reinstall

Dec 1, 2008

I had my box reinstalled with same OS as before, Centos x64. I am creating a NEW VPS and assigning it an IP from my Extended network (not primary) and the IPs are not pingable as if GATEWAY= was missing from the ifcfg config on network-scripts.

Hypervm And Openvz Vps

Apr 25, 2009

I am trying to create some vps using openvz but after creating the vps with the Centos basic template 304mb i can't ping the ip and i can't view the centos welcome page in my browser (using ip and not domain, so i don't need to change there anything yet) and the most important is that i can't connect to the vps using ssh

I aks for many good users about my problem but i don' found a solution yet.

I ask my DC about ip's and they told me that the ip's are routed in my server.

I follow this instructions:

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 50G 2.8G 44G 6% /
/dev/sda3 198M 21M 168M 11% /boot
/dev/sda5 408G 2.4G 385G 1% /vz
tmpfs 1012M 0 1012M 0% /dev/shm

I follow this:

I disable selinux by editing /etc/sysconfig/selinux and changing the line to selinux=disabled
and then run:

I just login using ssh as root and run the folllowing commands.
Did i have to move to another directory to run them or ?

setenforce 0

Next i open /etc/grub.conf
vi /etc/grub.conf
and change default=1 to default=0

Then i add the ip's at the pool and create a plan and then create a vps without any errors but nothing.

I try with my DC resolvers or the but nothing.

I alo add at the settings the gateway with no results at all.

After all i can't ping the ip that the vps got from the pool even ping it and not possible to connect to it using the ssh Sad

When you're creating VPS container, you can ssh with that IP and login with your username and password correct? But, what is the problem when I successfully created a VPS, and when trying ssh into it, I can't. Ok, here we go. I want to create a 2nd vps and will be using it as my DNS server. I enter a set of IPs into HyperVM's IPpool. First IP: x.x.x.178 Last IP: x.x.x.182 Resolv Entries (space Separated) : Gateway (IP): x.x.x.x.177 NetMask:

Then I created a vps resource plan. And then I created a VPS and it use the first IP from above. I want to connect to SSH and want to make it as my DNS server but seems the IP are not responding, it wasn't even live. So, what is the problem here? Where I did wrong? Just to let you know, I successfully created 1 VPS before that and it works without any hiccups. Got even whm/cpanel installed as well on it. The thing that I suspected is that my DC pulled the IPs off me and assigned them to other server. Waiting for their reply on this though.

Virtuozzo Vs OpenVZ/HyperVM

Apr 2, 2009

As a provider of Virtual Private Servers im looking at ways to expand our business, I love the fact that we can offer our clients such a good service with the low price we presently charge but as a "Client" or "Potential Client" what would your views be on Virtuozzo?

Is it worth our business cutting our already low profits and going with Virtuozzo as our VPS Control Panel?

This is something we are very interested in doing and we feel it would be a big jump from the very low-end budget HyperVM/OpenVZ Approach.

Your Views on the Virtuozzo Vs HvM/OvZ would be very helpfull.

Would you rather buy a low priced Virtozzo VPS or an even lower priced HyperVM powered VPS? Im quite lost as to wether the financial investment would be worth it, I don't see how it wouldnt be as HyperVM is very buggy and really doesnt give a full sense of security in my personal opinion.

[HyperVM/OpenVZ] How To Change VPS ID

May 13, 2009

I need to move a slave server from one master to another, but when running "import HyperVM VPS" I get the classic error:


Alert: The vpsid 470 : localhost exists on another server.

Please confirm exactly how to change the VPS ID for an OpenVZ VM as I've gone through all the LxLabs posts dealing with this subject and none of the proposed solutions work correctly.

Neither of these HyperVM commands work:


/script/shift-vpsid slave-id 1000

This method doesn't work:


vzctl stop 470
mv /vz/private/470 /vz/private/430
mv /vz/root/470 /vz/root/430
mv /etc/vz/conf/470.conf /etc/vz/conf/430.conf
(On master: echo "update vps set vpsid = '470' where vpsid = '430'" | hypervmdb)
vzctl start 430

[HyperVM/OpenVZ] Checking How Much Free RAM Is Available

May 14, 2009

Calling all HyperVM/OpenVZ gurus!

Since OpenVZ offers both base RAM and burstable RAM to VMs, checking how much RAM is still available for assigning to VMs is still done manually by me.

Is there a way to list the total amount of base RAM that has been assigned, and the total amount of burstable RAM that has been assigned, so that you know how many more VMs you can create/host on a server?

HyperVM (OpenVZ) To Virtuozzo Migration

Jun 27, 2009

Does anyone know how you can move an entire HyperVM (OpenVZ) Node to Virtuozzo. What has to be copied because we tried coping /vz/private/<VEID> and /etc/sysconfig/vz-scripts/<VEID> and we were not able to get the VE to start. We were getting an error:

Starting Container ...
Can't mount: /vz/template:/vz/private/1110 /vz/root/1110: No such file or directory
Container start failed

We tried rebooting the server as some other sites mention but still no luck. Any help is greatly appreciated because when we contacted Parallels they did not seem to have answer. (we are still waiting on a ticket reply though)

Transition: OpenVZ (HyperVM) To Virtuozzo

Jun 10, 2008

Its becoming more and more difficult to manage VPS using HyperVM and I am personally sick of the control panel design.

So does anyone have any great ideas to move all the VPS in HyperVM (OVZ) to Virtuozzo (PIM)?

If there isn't, I think I'll have to move all data across the orthodox way - which I clearly want to avoid.

PS: OVZ is on a different node from the VZ (duh!) but also will be utilizing different IP ranges. So, I think I need advice on changing IPs of the VEs too.

Incorrect Mem Usage (OpenVZ / HyperVM)

Nov 1, 2007

In the last two weeks I have noticed a major issue concerning memory usage. HyperVM and Top (via console) report two very different amounts of memory being used. On a fresh rebuild, my overall usage should be no more then 22mb. However, HyperVM reports 45mb whereas Top reports 11mb. Notice the huge gap?

I was told by my VPS host that OpenVZ / HyperVM is to blame. The overwhelming issue is: if I pay for 256mb of ram and I'm being cut short, then I'm obviously over paying. What's more: how can I tell whether or not I'm being cut short?

Has anyone run across these problems in the last two weeks?

Plesk 12.x / Linux :: After Full Reinstall Imap Doesn't Work Anymore

Mar 20, 2015

I'm using Ubuntu 14.04.2 LTS and Plesk 12.0.18 - update 38. Since i have reinstalled 3 servers, i don't have imap connection possible in some case.

- When i connect from a Thunderbird, it works only if it's not secure : any attempt with ssl is refused.

- When i try to use a smartphone with the same working config done in Thunderbird, i canno't log whatever i do to find something working on the smartphone (note : it's works with pop)

- Horde refuse all users. If i switch to Roundcube, all works...

There is something wrong : i search the web, the forum, for 14 days now, without success. I tried many thing from the KB...no success either.

OpenVZ/HyperVM On Multiple NICs Advises

Jan 9, 2009

My company currently have some spam filtering problem with mailscanner and the Windows team was given a project to come up with a better solution to fight spams.

I work in Unix dept. I suggested to Windows admin I use ASSP personally and works great. I gave them the specs on my setups. Since the current front-end proxy is on RHEL, we all settled to try out ASSP on Ubuntu based server.

We scrap-find an older Dell PE 2850 we can use. I finally convinced company to deploy OpenVZ, this will be our first OpenVZ server public facing.

The Dell have two Intel 82541GI Gigabit NICs. We are VLAN-ing on Cisco switch level; eth0 will be on internal 10.0 network and eth1 on public port.

I already installed CentOS 5.2 plus HyperVM. I configured and brought up eth1 without TCP/IP, just on layer 2. Looks like OpenVZ is using eth0 right now.

For this new proxy, will be routing traffics through host eth1. What's the best way of going with this? The new proxy will be using veth so it will have its own MAC (for security reasons; and network team said this is mandatory).

Should I be using bridging? Or simple routing guests through VZ configured eth1 would work?
Can anyone give me some ideas? I'm asking in WHT is because a lot of hosting companies probably have this setup already. I'm just absorbing ideas...

OpenVZ/HyperVM Unable To Fork: Cannot Allocate Memory

Jun 5, 2009

We're in the process of setting up our new VPS Server, and we can create a VPS with 256MB memory and with 512MB memory fine, but when creating one with 1GB memory, we get the error:

Could Not Start Vps, Reason: Unable to fork: Cannot allocate memory: Not enough resources to start environment: Container start failed:

Even though the server has 4GB RAM and no other VPS's running. Any ideas?

[Edit]We now seem to get the problem for all our VPS's. I think it may be something to do with the Server not unallocating the memory, as we've provisioned and de-provisioned quite a few Servers

Plesk 12.x / Linux :: How To Reinstall Fail2Ban Entirely

May 7, 2015

So on our server, fail2ban got itself in a mess. Tried various things to fix, to no avail, so figured I'd just do a fresh install of it. There was minimal customisation to it that I couldn't re-do.

Note I'd already rm'd /etc/fail2ban - as on previous attempts, the files in here didn't appear to be restored to their defaults. So I figured removing the directory would force this to happen (Whether this was wise I'm not sure!) ;-)

So, following instructions here: [URL] .... I now get the following:

# wget http://kb.sp.parallels.com/Attachments/kcs-36245/fail2ban.gz
# gunzip fail2ban.gz
# mv fail2ban /etc/init.d/fail2ban
# chmod 755 /etc/init.d/fail2ban
# ll /etc/init.d/fail2ban /etc/fail2ban/fail2ban.conf
ls: cannot access /etc/fail2ban/fail2ban.conf: No such file or directory
-rwxr-xr-x 1 root root 2141 Aug 15 2014 /etc/init.d/fail2ban

I then uninstall/reinstall with # /usr/local/psa/admin/bin/autoinstaller

(Have tried via the web interface too)

I then get:

# ll /etc/init.d/fail2ban /etc/fail2ban/fail2ban.conf
ls: cannot access /etc/fail2ban/fail2ban.conf: No such file or directory
-rwxr-xr-x 1 root root 2141 Aug 15 2014 /etc/init.d/fail2ban

i.e., no change..

and if I go to the fail2ban settings in Plesk, I get:

Internal error: f2bmng failed: ERROR:f2bmng:No section: 'Definition'
Message f2bmng failed: ERROR:f2bmng:No section: 'Definition'

Is there a way to regenerate what should be in /etc/fail2ban by default?
