I'm using a brand new Virtuozzo VPS, with (512mb) SLM memory managment, that standing to some "experts" would be a great way to manage memory, a great virtualization solution, and such.
This VE, supposedly, is hosted on excellent hardware (sas-scsi raid i/o, etc), so should have great performances, especially considering i don't run any control panel, i just run apache2+mysql5 (no email system or else), and i manage everything by myself (and i'm really experienced).
I'm experiencing on the contrary much worse performances than my previous 256mb XEN vps.
Sometimes you hear (virtuozzo fanboys i guess) about XEN slowness problems instead, because xen - supposedly - hasn't got a proper disk/io scheduler BUT provides individual custom swap space, so a customer could create a 5GB swap space and disrupt host machine performances by clogging the VPS, swapping a lot, causing insane i/o wait, etc... I've read a lot of topics about this "debate" in the past.
So you would expekt Virtuozzo having a wonderful cpu and disk i/o scheduler, instead.
You can read on Virtuozzo Website the following Claim : "Complete Isolation - VEs are secure and have full functional, fault and performance isolation."
On the contrary i'm having a lot of issues, supposedly coming from "bad neighbours", like idiots not being able to handle security of their vps, spammers, and so on, on my new virtuozzo VE ...
Everytime someone crashes his own VE on the same host machine, like causing a 100.0 load, even my VE goes offline with 400% i/o wait ...
My hosting provider (which i won't name at all, anyway) is doing an excellent job trying to minimize my inconveniences, really: but - in general - i'm beginning to wonder wheter this insane behaviour is "common" for a virtuozzo solution.
In short, I'm wondering - and i'd like an expert opinion on this - HOW THE HECK could this be possible ??
Isn't Virtuozzo supposed to have a I/O and CPU scheduler ? How in the earth can a single abuser loading insanely his VE affect all the other customers VEs ?
Can a host-server running Virtuozzo, be monopolized (100%cpu and insane i/o wait) by a single abusing VE ?
If this is true, i really don't understand where Virtuozzo advantage would be. Neither i understand the "complete performance isolation" claim by SwSoft.
Does, by chance, a SteadCom representative visit this forum?
The problem: I can't receive a new password to the client area (no email is sent from SteadCom after I use 'forgot password' feature), the VDS I had is I suppose suspended and I have no means neither to access the user cpanel to pay/renew, nor to use live talk with support - the link on the site does nothing.
just wonder if anyone ran into this problem. We were collocating our server with a "certain" provider and decided to move it elsewhere due to their lack of service. Everything was going OK even the outrageous termination fee and the shipping fee that we had to pay. However, after the host received the payment they went completely silent on us ignoring all of our emails and phone calls. I've spoken with our lawyer who estimated the legal actions against them could cost us thousands of dollars. The physical cost of the server was about $2,000 so I'm not sure if legal action would be worth it. Anyone has any suggestions on what else we can try to get our server back.
I have some websites with different support, contact, ... forms. I have set the forms to record the subscriber IP, need to know when the IP begins with 10, it means a person submitted the form from inside the server? If so, what is the appropriate defense? If no, what it means? I know many experts are present here, please in addition to selling and introducing your service,
I cant seem to get in touch with either support/sales on Myriad. Anyone have an alternative email/IM contact for them? Anyone else having trouble contacting them?
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've noticed a lot of the recommended VPS' are using Virtuozzo (e.g. KickAssVPS and WiredTree). Can anyone recommend good Windows VPS that utilize other software (ESX, Xen, Hyper-V)?
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.
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.".
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.
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: Low Strength Ciphers (< 56-bit key) SSLv2 EXP-RC2-CBC-MD5 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export SSLv3 EXP-EDH-RSA-DES-CBC-SHA Kx=DH(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-DES-CBC-SHA Kx=RSA(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-RC2-CBC-MD5 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export TLSv1 EXP-EDH-RSA-DES-CBC-SHA Kx=DH(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-DES-CBC-SHA Kx=RSA(512) Au=RSA Enc=DES(40) Mac=SHA1 export EXP-RC2-CBC-MD5 Kx=RSA(512) Au=RSA Enc=RC2(40) Mac=MD5 export EXP-RC4-MD5 Kx=RSA(512) Au=RSA Enc=RC4(40) Mac=MD5 export Medium Strength Ciphers (>= 56-bit and < 112-bit key) SSLv2 DES-CBC-MD5 Kx=RSA Au=RSA Enc=DES(56) Mac=MD5 RC4-64-MD5 Kx=RSA Au=RSA Enc=RC4(64) Mac=MD5 SSLv3 EDH-RSA-DES-CBC-SHA Kx=DH Au=RSA Enc=DES(56) Mac=SHA1 DES-CBC-SHA Kx=RSA Au=RSA Enc=DES(56) Mac=SHA1 TLSv1 EDH-RSA-DES-CBC-SHA Kx=DH Au=RSA Enc=DES(56) Mac=SHA1 DES-CBC-SHA Kx=RSA Au=RSA Enc=DES(56) Mac=SHA1
Anyone have any suggestions on how we can resolve this issue for the client?
Does anyone know the basic information for the Virtuozzo API? We are working with Matt from WHMCS to create a custom module for Virtuozzo to auto provision VPS's however the API docs we submitted were not sufficient as there were no clear "functions".
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.
