JVM On A Xen Or A OpenVZ
We are looking for a VPS to house a scala framework running on a JVM, from what I can gleen Xen would be the best route for us or is it possible that openVZ with enough dedicated ram would suffice, does anyone have a view on this?

Xen / OpenVZ Kernels?
On a recent Xen VPS trial, I noticed two kernel versions. "2.6.9-42.0.2.EL.xs148xenU" was being used, but 2.6.18X was installed (source & headers). While trying to set up OpenVPN, I noticed my modules.dep was missing. I could be wrong, but I was under the impression that I needed the Kern source in order to make the module dependencies. At any rate, I can't find the kernel versions in question and was wondering where / if they're provided for Xen users. (By the way, I was running CentOS 5)

VPS - Mananged, Non/ Xen Or Openvz
i am looking to get away from hostgators extremely overloaded servers and get a vps. I have been admining linux servers for a while although never as a web server, but think i can handle that aspect. I have done a huge amount of research but dont know which way to go. One of the things thats rough is the control panels, i like cpanel and have only used cpanel but many charge alot for it. I have been considering an xl-256 plan from vpsland.com. they are east coast (i am in NJ, west coast is out) and their xl plan is xen with swap. But its $15 for cpanel and that is too much, i was thinking of trying directadmin for $6. Is directadmin any good? I need spamassasin and that stuff of course. To me its crazy that openvz has no swap and the server will crash if you reach max ram like at vpslink.com. I really liked vpslink.com's phone support but the west coast thing is rough. I have been looking at http://www.ubiquityservers.com/vps/new-york.php these guys but its virtuozzo, but cpanel is cheap only $5 a month. bodhost.com seemed cheap at $8 for cpanel. then i found this which sounds great! especially since its close but i emailed them to ask if its xen or openvz and havent heard back in almost 12 hours which scares me for support. i like phone support but vpslink.com again was on the west coast. their cpanel was cheap though at $8. plus i dont know if i want managed ro not then i remembered this site, and remembered i had gotten alot of help hear before so i figured it be best to hear others experience and favorites, etc.

Do You Prefer OpenVZ, Virtuozzo Or Xen?
This poll is purely for market research but I figure other VPS providers might get some info out of it. Its a simple question to customers more than hosts. Do you prefer OpenVZ,Virtuozzo or Xen and why? I personally know which I preferr from a providers point of view but wondered about clients Assume hardware is equal. OpenVZ/Xen have a custom control panel (HyperVM or similar). Virtuozzo has VZPP

High-End VPS - Prefer OpenVZ Or Xen
If you were looking for a high-end high-performance high-reliability VPS. Say a 100gb disk space, 2,000gb transfer, 4gb ram VPS with cPanel for around $115/month. Disk space, transfer, and ram would be *guaranteed* with no overselling, before people start going off on that tangent. Would you prefer OpenVZ or Xen - and why? Your only options are OpenVZ and Xen, I don't want to hear why you think XYZ's virtualization would be better than OpenVZ and Xen.

Overselling In OpenVZ
Just how it actually works? I have a pretty good knowledge about Xen and Linux KVM (somewhat about VMware as well). Prior to joining WHT, I rarely heard about Virtuozzo and OpenVZ. I'm just interested in RAM usage actually. I also read on some threads that you can oversell storage and net bandwidth as well? That just seems a little weird to me. I also used a fairly good amount of Solaris Zones as well. Example, if I have a 8GB box and I leave some, say 512MB, reserved for CT0. 8192-512=7680 (I know the ACTUAL RAM amount will NOT be 8192), that leaves 7680MB use for CTs. So technically in OpenVZ if you dice out dedicated 512MB VEs... you end up with 15 right? So you are able to sell more than 15 VPSs on a 8GB server box? If also set all burstable RAM to 1GB for all VEs. In Xen, when you set dedicated RAM it is taken away from dom0, period. That's all there is to it, no oversell (Xen 3.3+ you can use ballooning to overcommit RAM, I know). Within CT in VZ, user is able to check beancounters to see the guaranteed/burstable RAM. Technically you can't lie to the users. I researched around... when oversell in VZ and the RAM gets maxed out... VZ will try to slow/stop/kill processes in order to keep the guests happy, to me that's just dangerous. Why needs to kill processes for RAM saturation? Anyone can shed some lights for me? Or point me to an article(s). It can be technical, I should be able to grasp.

HyperVM+OpenVZ
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: 255.255.255.248 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.

OpenVZ Questions
I am aiming to offer VPS based on OpenVZ. Have some questions, please help to answer - in OpenVZ, is there any monitor script, that will release an email to say one VPS is down? Or will I need to use external monitoring? - can I do the backup / restore of full VPS within OpenVZ? Can customers do it themselves? - how hard to change the VPS configuration? For example, upgrading from 256MB RAM to 512MB RAM, or adding more CPU, space...? - how about the IP control in OpenVZ? Let's say each VPS will have 2 IPs, so to prevent customers adding more IPs, I will need to setup VLAN, is that correct? How hard is it in OpenVZ? - how about the ideal hardware for running OpenVZ? Saying SATA, or SCSI disks, how many RAM... for example

Virtuozzo Vs OpenVZ/HyperVM
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 And Openvz Vps
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 wget[url] 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 4.2.2.1 4.2.2.2 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

OpenVZ Max Ram
I am being told that when a VPS in openvz hits the maximum ram assigned to it that openvz disables that vps. Isn't the ram limit a hard limit that simply restricts the available ram to that container to XX ram? Is this normal?

Why Do Providers Prefer OpenVZ
I was wondering why so many VPS providers use OpenVZ instead of Xen. I can understand using OpenVZ if you want to oversell, but if you have guaranteed memory with a OpenVZ plan, isn't that the same as allocating the memory in Xen? Am I missing something or something else?

OpenVZ Burstable Memory
Let say your VPS has 128MB of memory. My understanding would be that if you had, say, another 128MB of 'burstable' memory, that if another guest on the system wasn't using all it's memory, or if there was some spare on the system, then your VPS could use that. But, how much memory does your VPS really think it has available? and what happens if the other VPS (or the system) decides it wants it memory back? Does OpenVZ just start killing off your processes until it free's up enough memory?

Clock Issues With OpenVZ
I have an VPS at cheapvps.co.uk since November 2007. It has worked like a charm until a week ago. Since the massive crack from last week and the subsequent shutdown & boot, the clock on my VPS is going crazy. Clock is really accelerated, a minute in the real world equals to more than 2 minutes within the VPS. I'm having lots of problems with dates in the future, and cheapvps support team is working to get this solved with no success.

OpenVZ - HN Can't Ping VE
I'm running my own OpenVZ server with a few VPS's running on it and have a small network issue. I can't ping any VE from the HN. All the other networking is working ok (strangely I can ping the HN from the VE) apart from this. It's a simple setup with one network card connected to the internet. OpenVZ the latest stable version running on CentOS 5.2 I'm pretty sure it's not a firewall problem but is something to do with arp or routing and one of the settings in sysctl.conf Has anyone else seen this?

[HyperVM/OpenVZ] How To Change VPS ID

Centos RAID Configuration For OpenVZ
Would this be a good setup for a VPS Serving system with 2x 500gb hard disks (up to) 8gb memory.... (Looking to use OpenVZ to create about 14-15 512mb VZ VPS's)? Host machine to do nothing other than host the VPS's. Host O/S to be Centos 5 x64, guest O/S's to be the usual OpenVZ supported linuxes. Make 2 software raid partitions 120mb, each | +- Make RAID 1, mounted at /boot Make 2 s/w raid partitions Remainder of drive | +- Make 1 LVM Physical Drive, using RAID 1 | +- Make Logical Partition, 20gb, mounted '/' +- Make LP, Swap 16gb +- Make LP. ext3 remainder, mounted as '/vz' Is it important what order I should make the Logical Partitions? Should I create a /tmp partition? If so, how much?

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.

Transition: OpenVZ (HyperVM) To Virtuozzo
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.

Openvz Kernel Vs Dedicated Kernal
I have a company offering me the follow: Core 2 Quad Q6600 Processor 1 GB RAM 250 GB Hard Drive 500 GB Bandwidth 5 Usable IPs Free Cpanel The issue here is that they're not real dedicated servers, they're Openvz Dedicated Kernel with Quad Core CPU. The question I have is does anyone have any experience with openvz servers and how does the performance add up compare to dedicated servers? The hosting company says they do it this way because they get cpanel licenses cheap so can give it away for free. Any thoughts?
