View 5 Replies View RelatedVirtuozzo VPS System Usage Meter Wrong
Jan 10, 2009I have noticed a weird thing lately with two VPS accounts. Virtuozzo's system usage meter on the Resources page creeps up to 100% over the course of 24 hours or so and stays there, but stays green and I don't get any QoS alerts. The servers both seem to be running fine, and I haven't had any crashes. One VPS is running a few Wordpress blogs.
The other is running some Joomla sites.
Both are running Virtuozzo on CentOS 4.7 i686 with WHM 11.24.2 and cPanel 11.24.4-R32486.
In the past, when the system usage meter in Virtuozzo got anywhere near 100%, it turned yellow or red, I had sites go down, and all kinds of QoS alerts for privmpages were thrown. It turned out back then that I had a bad PHP script eating tons of memory with too many MySQL queries. That doesn't appear to be the case here, since I'm not having any apparent problems with either server. It seems like a "non-problem" but it has me concerned because I'm used to using that system usage meter in Virtuozzo to keep an eye on the health of the VPS..
When I look at memory used in WHM (WHM->Server Status->Server Status) it shows only 31% used, which is what I used to see in Virtuozzo.
When I run free, I get:
root@server [~]# free
total used free shared buffers cached
Mem: 524288 133804 390484 0 0 0
-/+ buffers/cache: 133804 390484
Swap: 0 0 0
When I run Free, I get:
root@server [~]# Free
Memory limit...: 8388604 MB (burstable: 8388604 MB)
Current usage..: 120 MB (0%) (requested: 264 MB)
Free memory....: 8388484 MB (100%)
Initially, I suspected it was another problem with MySQL, and restarting MySQL does drop the system usage meter down to ~31% in Virtuozzo for a while--without changing the actual memory used on the System Processes page--but the memory usage for MySQL with Virtuozzo pegged is only 6.23% in WHM.
Here's the really weird thing: If I look at Virtuozzo->System Processes it shows only 0.4% (I think they mean 40%) of total memory used, half of which is mysqld and the rest is spamd.
With no sign of problems, it looks like Virtuozzo is incorrectly reporting memory usage in the system usage meter, but correctly in the system processes list.
The web host's response was:
We use SLM for managing VPSes. This enforces your per VPS limits and doesn't let your VPS use more then it should be. It sounds like you guys may have some memory hogs in your applications.
Have you guys considered cutting down some of the unneeded plugins and stuff?
That doesn't make any sense to me given the disparity between the memory usage meter and the amount of memory usage reported in System Processes and with free/Free as well as the lack of QoS alerts, but maybe SLM prevents any alerts? I don't want to let a memory hog run free on my system if one exists.
Plesk 11.x / Linux :: Secure Connection To System When Posting Data - Install PEM Certificate
Nov 20, 2014I've written a script to send property data to rightmove.co.uk as part of their new automated data feed. However they require a secure connection to their systems when posting the data. They have provided me with a .pem file which is a security certificate. I need to install this on my plesk server but where to start as most certificates require a private key and the actual certificate. The private key I have been provided is only an 8 charter string, like a password.

Xen Or Virtuozzo
Jun 6, 2008We'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.

View 14 Replies View RelatedAPF & Virtuozzo
Jul 26, 2007I 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?
Python On Virtuozzo

Code:

Error: Python directory not found in /vz/pkgenv/rpm46x64

The only recent changes that have been made is the Hostname. Before making this change, I was caching OS templates like it was christmas.

Virtuozzo On All Server
Feb 10, 2008I 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.

Virtuozzo /dev Problems?
Apr 17, 2009I 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, 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!
Virtuozzo And Windows
Nov 7, 2008Has 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.

Jan 29, 2009which 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)
PCI Compliance With Virtuozzo
Dec 4, 2008We 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:

Mar 2, 2009I 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.

Mar 27, 2009Does 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.
